Introduction
In 2017, youth groups aged 20-24 years who was a period of higher education had a suicide rate of 4.94 per 100,000 people. In 2018, this rate increased to 5.33 per 100,000 people, including information from a phone call for advice that found youth groups called to consult for more mental health issues. In addition, those who called for advice were 14.60 percent of children aged 11-19 years and 20.10 percent of youth aged 20-25 years in 2018. It found that the most problems in children and youth related to stress, psychiatric problems, love, depression, and family problem. In 2019, there were youth groups aged 11-25 years who continuously called for advice about 33.61 percent of all counselors. Moreover, the department of mental health presented information about depression and suicide rates among youths and undergraduate students which tended to increase. (The department of mental health, 2019). Therefore, youth groups or undergraduate students faced more stress with high risk of suicide.
However, online mental health care services had trend to be more popular. Vongthangsawat (2016) studied the effect of individual existential humanistic online counseling on the wellness of undergraduate students with neuroticism. In this online consultation process, psychologists advised students to review their problems and self-awareness through the conceptual framework of existentialism-humanism. They supported students to choose a new way of life that was consistent with their own. It found that this online counseling was effective for well-being of students with high emotional instability and low emotional instability. Students felt more secure and relieved sadness and anxiety in their lives. counseling among university students. They found that students had a positive attitude with both methods of counseling. The results showed that students with mental health problems were more likely to get online psychological counseling. Therefore, psychological counseling services by using digital media had easier access to the service for university students and may lead to a change in face to face psychological counseling.
In Australia, an online psychological consultancy study was conducted. It found that this counseling services were growing. The psychological counseling methods included email, web-based messaging, video conference, and other forms. The advantages provided flexible service in remote areas, self-protection reduction of clients who had to reveal stories to stranger service providers, low cost, and ability to record advisory services electronically. However, the study did not show that online counseling had more effective than face-to-face counseling. But results reflected effectiveness equally (Chester & Glass, 2006). Therefore, mental health with online methods had more popularity and were effective methods. From these reasons, researchers interested to develop the online application based on LINE system that was popular among undergraduate students (Cherdchuchai & Yenjabok, 2014) for well-being promotion. LINE was a Japanese instant messenger application using for communications on electronic devices such as smartphones, personal computers, and tablet computers. This freeware application was similar to WhatsApp and WeChat. Users could be texting, voice calling, and messaging wherever internet was accessed. In Thailand, LINE was more well-known than WhatsApp and WeChat, so this research developed application enhancing undergraduate students' well-being based on LINE system. The students of the faculty of education, Kasetsart University were selected for this study because they would go to be a teacher which required a good health for taking care of oneself and their students. In this study, the application named "Friend from heart" as a sincere friend who cared of mental health and physical health for well-being.

Literature Review
The objective of this research was to promote well-being which including physical health and mental health. Therefore, literature review was divided into 2 parts; 1) the relationship between physical health and mental health and 2) application for taking care of physical health and mental health.
World Health Organization defined health as a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity (World Health Organization, 2000). From the definition, it could state that physical health and mental health had relationship. Physical health can be defined as a normal function of the body at all levels; a normal course of biological processes that ensures individual survival and reproduction; a dynamic balance between the body's functions and the environment; participation in social activities and socially useful work; performance of basic social functions; the absence of diseases, painful conditions, and changes; and the body's ability to adjust to the constantly changing conditions of the external environment (Koipysheva, 2018). While mental health was defined as a state of well-being whereby individuals recognize their abilities to cope with the normal stresses of life, work productively and fruitfully, and make a contribution to their communities. (World Health Organization, 2003). Ohrnberger, Fichera & Sutton (2017) studied the relationship between physical health and mental health. They found that past mental and physical have strong indirect cross effects on current mental and physical health. The key indirect pathways were past cigarette consumption, past physical activity and past social interaction. Similar associations applied for the relationship between past mental health and present physical health.
Promoting physical health and mental health in world 4.0 could use digital technology. So that there were a lot of application program development on a smartphone as a way to help people with mental health problems. For examples, FoodiEat was developed by The National Electronics and Computer Technology Center (NECTEC) (2016) to help users record and receive daily diet and exercise advice in order to use as a guideline in self-care. FoodChoice was developed by Thai Health Promotion Foundation and The National Electronics and Computer Technology Center (NECTEC) (2018) to educate children to perceive understand and aware risk factors in promote health to prevent disease.
Mood Kit was developed by Dorian & Erhardt (2016) which designed to help people with depression. It based on Cognitive Behavioral Therapy (CBT) as applying effective strategies from psychological experts. MoodKit had integrated tools to help users enhance their emotional activities, identifying and modifying ineffective thoughts, ratings and making mood charts, and creating a notebook to support well-being. The using menu followed: 1) Mood Kit activities for creating positive emotions to reduce negative feelings and enhance well-being. 2) Thought checker for checking their own ideas to enhance positive feelings. 3) Mood Tracker for rating an own mood chart on a daily basis and monitoring the progress of their emotions. 4) Mood Kit Journal for developing self-awareness and attitude. (2018) which provided innovative and easily accessible mental health services. The objective of this application was to use CBT strategies for solving anxiety and depression. The CBT-based therapies were provided by trained counselors. The development process consisted of 1) The development of ideas from the conceptual set 2) Empirical evaluation 3) Software and plans for behavior management 4) User feedback and 5) Public launch. The sample group tested the application with mobile application rating scale and provided feedback. It was rated as a higher standard health application than the general entertainment application. Mood Mission had objectives of 1) To help the self-management problem prevention and reduce the risk of emotional and anxiety disorders 2) To be a platform that supports the care of people with low mental health 3) To strengthen the face-to-face psychotherapy for depressed people. Therefore, the Mood Mission application was designed for easy using, strengthened the mental health and well-being of smartphone users in all ages and people with various mental health levels.

Mood Mission was developed by Bakker, Kazantzis, Rickwood & Rickard
Lovejoy, Buch & Maruthappu (2019) created Artificial intelligence (AI) to look after university students who had mental illness dues to the traumatic event (Post Traumatic Stress Disorder (PTSD) or depression. AI included 1) CBT chatbot: the form of a conversation that transmitted through CBT therapy or Woebot for reducing student depression and anxiety. 2) Meetings for treatment and privacy: a consultation service about mental health and physical health by meeting psychiatrist online which reduced a traveling time and protected privacy. The results showed that the MoodKit and MoodMission applications could significantly reduce depression. There was no application that causes a lot of anxiety. However, the results did not find that all 3 applications were designed to reduce both depression and anxiety during the same period. The using duration affected mental health promotion. In addition, MoodKit and MoodMission could enhance the ability to manage stress with statistical significance. The result from idea management was not found in the Mood Prism application.
For the study of mental health applications in Thailand, the department of mental health has developed an application called Sabai Jai. The objective of this application was to assess the psychological condition of individuals. The application had 5 categories of operation menus which were: 1) Answering questions for giving information about suicide occurring, characteristics of distress, the nature of physical disease that had risk of self-harm, behavior that showed intentions of self-harm, warning signs of suicide problems, including a cognitive video about depression. 2) Screening test by observing oneself or close people who were at risk of self-harm. If it was effective, the application would have suggestions "risk of self-harm" appear below the results of the screening. 3) Talking with someone for adding a list of people who want to talk with by filling the name and phone number 4) Mental health hotline for calling the hotline department of mental health (1323) to consulted with experts via phone call.
According to a study of smart phone applications that promoted mental health in Thailand and abroad, it found that all applications aimed to reduce depression and anxiety as well. There were important menus that include: (1) Providing information about mental illness and ways to prevent stress, (2) Providing self-examination, (3) Using chatbot for basic help, (4) Recording important events in each day which affects emotions of users, (5) Activities to enhance mental health, and (6) Talking with a psychologist/psychiatrist. Therefore, it required effective functions of application menus for developing an application to promote well-being.

Discussion
The development of "Friend from Heart" application had 3 main operations including providing mental health information, providing physical health information, and providing counseling services. These operations were consistent with the study of applications that care for mental health in foreign countries. It found that most developed applications provided mental health information (Dorian and Erhardt, 2016;Bakker et al., 2018;Lovejoy et al., 2019). As well as some application designed to provide psychological counseling services including a comfortable application developed by the Department of Mental Health of Thailand. This application had a function to be able to discuss mental health problems (Department of Mental Health, 2019). Therefore, the "Friend from Heart" application was comprehensive and covered knowledge about mental health and physical health including psychological counseling services with the idea of being a sincere friend. The application suited with the age of students in the late teens who focus mainly on their friends (Engler, 2009).

Conclusion and Recommendation
In conclusion, LINE "Friend from Heart" application was developed to provide information about physical health and mental health with mental health counseling for undergraduate students under the concept of friendship. There were 3 types of services including Chatbot, Live Chat, and Call. However, this research did not have the function of checking one's own emotions like foreign applications which may be the part for researchers to develop further.
