This research attempts to analyze the effects of demographic factors, socioeconomic factors, health behaviors and social/familial supports on health inequalities among Korean elderly. For this end, this study adopts the multiple linear regression analysis to process data on population aged over 65 contained in 'The Third Korea Welfare Panel Study' published in 2008. The following are the results. First, the less educated they are, the smaller income they earn, the less they drink, the less satisfied with relationships with their family members, the more they turn out to feel depressed. Second, the less educated they are, the smaller income they earn, the less they drink, the less they are satisfied with relationship with family members, the more they benefit from social welfare services, the worse they turn out to rate their health. Based on these findings, three following suggestions could be forwarded. First, vulnerable aged groups including female elderly, low-income elderly, less-educated elderly need customized social supports. Second, new social policy for households is required to enhance elderly people's satisfaction with their family relationships with the rapid trend of a growing number of nuclear families and aging. Third, social welfare service programs need to be reevaluated to enhance their function for the aged.

Shin Hong-gyun was born on August 20, 1881. The second son of Shin Tae-geom (申泰儉) in Sangsang-ri, Sinbukcheong-myeon, Bukcheong-gun,Hamgyeongnam-do. His family had been practicing East Asian medicine as a family business. At that time, the families of East Asian doctors who passed the general examination of the Joseon Dynasty had been continuing the East Asian medicine business from generation to generation. Starting with exile in North Gando in 1911, he was located in Wangga-dong, 17 Doo-gu, Changbaek-hyeon. In 1915, he met General Choi Un-san in Bongo-dong, treated the soldiers suffering from cellulitis, and participated in the training process to prepare for the upcoming anti-Japanese war. However, because of a growing difference of opinion with General Choi Woon-san, Shin Hong-gyun left Bono-dong after a year and mets Sorae Kim Jung-geon and joined the founding of Wonjonggyo and Daejindan, an anti-Japanese armed group. It is said that Shin Hong-gyun established many schools in Korean villages destroyed by the Gyeongshin disaster and 14 schools were established under the names of Wonjonggyo and Daejin. After the Japanese established the puppet Manchukuo in 1931, the Manchurian Defense Forces were formed. Koreans and Chinese immigrants to Manchuria worked together to carry out a joint Korean-Chinese anti-Japanese operation towards the Japanese Empire. In 1933, 50 of the Daejindan members joined the Korean Independence Army, and among them, Shin Hong-gyun began to work as a medical doctor in earnest. During an ambush in Daejeonryeong Valley, he could not get a proper meal and, to make matters worse, got wet in the rainy season, so the situation was a challenge in various ways. At this time, Shin Hong-gyun showed his knowledge of herbal medicine, picked black wood ear mushrooms that grew wild in the mountains, washed them in rain water, and provided food to the independence fighters and relieved them of hunger. After the Battle of Daejeon-ryeong, the Japanese army's suppression of the independence forces intensified, and most of the independence fighters escaped from the Chinese army's encirclement and were scattered. Ahn Tae-jin and others led the remaining units and continued the anti-Japanese armed struggle in the forest areas of Yeongan, Aekmok, Mokneung, and Milsan.

Under the Trump administration, the U.S. has made clear that "China is America's strategic competitor, revisionist power and a major challenge to America's prosperity and security." The Biden administration has largely inherited this perception of China. China has also responded without backing down. Therefore, the U.S.-China strategic competition has become the most important background factor in the international system and has a great impact on the security situation in Northeast Asia. Nevertheless, if you look at the recent process of establishing trilateral security cooperation among ROK, the U.S. and Japan, we can find that ROK's foreign strategy adjustment has played a key role. This is because establishing trilateral security cooperation among ROK, the U.S. and Japan depends on improving ROK-Japan relations. And the Yoon Suk Yeol government is pushing for rapid improvement in ROK-Japan relations regardless of domestic political constraints. The trilateral summit at Camp David laid the groundwork for future cooperation among ROK, the U.S. and Japan in security and other broader areas. China is strongly dissatisfied with the formation of trilateral security cooperation among ROK, the U.S. and Japan. However, this paper argues that although ROK agrees to form trilateral security cooperation with the U.S. and Japan, ROK's strategic objectives are not exactly the same as those of the U.S. and Japan. For example, looking back at the development of the U.S.-Japan alliance after the end of the Cold War, both the U.S. and Japan share similar views and perceptions of China's rise. The real goal of the strengthening of the U.S.-Japan alliance in recent years is also how to cope with China's rise. On the other hand, ROK's previous administrations have been negative about trilateral security cooperation with the U.S. and Japan. This is because ROK's main strategic goal is to reduce or eliminate threats from DPRK rather than respond to China. Faced with increasing DPRK's provocations and threats, more than half of South Koreans are in favor of reinforcing trilateral security cooperation with the U.S. and Japan to contain or mitigate threats from DPRK. As a result, if North Korea's nuclear and missile threats to ROK continue, then ROK's foreign strategy is likely to be to strengthen trilateral security cooperation between the U.S. and Japan to ensure its own safety and survival. If China wants to reduce the strategic pressure from the trilateral security cooperation among ROK, the U.S. and Japan, the best way is to reduce DPRK's provocations and threats to ROK and play a more substantive role in getting DPRK to give up its nuclear program.

Samama wood (Anthocephalus macrophyllus (Roxb) Havil) is a fast-growing and lesser-utilized wood species that has inferior properties; therefore, its quality needs to be improved. This research aimed to determine the effect of citric acid impregnation at high curing temperatures on the dimensional stability and mechanical properties of wood. Citric acid solution with 10% concentration (w/w) was impregnated into wood samples by vacuum-pressure method (-0.5 cmHg, 30 min; 0.7 MPa, 3 h), followed by curing process at 140℃, 160℃, and 180℃ of temperature for 1 h. In comparison, the other wood samples were heat treated at the same temperatures and time. The results showed that the increase in curing and heat temperatures for both treatments were directly proportional to the dimensional stability, but inversely proportional to the mechanical properties. Citric acid impregnated had higher density, dimensional stability, and mechanical properties, except for modulus of rupture, than that of heat treatment. The optimum temperature is suggested at 160℃ in both treatments.

In the current era of the global mobile smart device revolution, electronic devices are required in all spaces that people interact with. The establishment of the internet of things (IoT) among smart devices has been recognized as a crucial objective to advance towards creating a comfortable and sustainable future society. In-mold electronic (IME) processes have gained significant industrial significance due to their ability to utilize conventional high-volume methods, which involve printing functional inks on 2D substrates, thermoforming them into 3D shapes, and injection-molded, manufacturing low-cost, lightweight, and functional components or devices. In this article, we provide an overview of IME and its latest advances in application. We review biomimetic nanomaterials for constructing self-supporting biosensor electronic materials on the body, energy storage devices, self-powered devices, and bio-monitoring technology from the perspective of in-mold electronic devices. We anticipate that IME device technology will play a critical role in establishing a human-machine interface (HMI) by converging with the rapidly growing flexible printed electronics technology, which is an integral component of the fourth industrial revolution.

With a growing interest in the Han River Skyline, which greatly influences Seoul's image, careful consideration of the skyline form has become crucial in the redevelopment plans for apartment complexes along the Han River. The Seoul Metropolitan City government has lifted the height limitations for apartments along the Hang River to cultivate a vibrant skyline. However, traditional skyline analysis often overlooks specific attributes, limiting the provision of precise guidelines for Seoul's unique skyline plans. Despite advancements in Digital Twin technology, only some tools effectively manage urban skylines with preferred shapes. Hence, this study aims to make a substantial contribution to the advancement of a Digital Twin 3D modeling program capable of effectively managing urban skylines. This is achieved through the utilisation of Conjoint Analysis, which assesses the importance of each attribute in determining the preferred skyline shape. Focusing on Apgujeong apartment complexes along the Han River currently undergoing redevelopment or planned for redevelopment, the study analyses the preferred skyline shape to propose standards for the Digital Twin 3D modeling program development. It also suggests that Conjoint Analysis can be beneficial in this process.

The importance of start-ups and venture companies in the Korean economy is growing. However, the successful growth of startups and venture companies are still challenging as 70% of startups fail within 5 years. A new perspective on innovation is essential to overcome the liability of newness and the liability of smallness in the existing market and obtain the competitive advantage. Recent phenomenon in the Korean startups ecosystem is the remarkable growth of unicorns and future unicorns. Their business models, types of business, and success cases serve as a good example. Neverthless, the process of unicorn and future unicorn startups making new industries and innovative business has poorly understood. In this paper, we first define 175 unicorns and future unicorn startups participating in the K-unicorn project as a unicorn group and analyze current trends of the group. Then the in-depth analyses of industry sectors are conducted. Specifically, focusing on the unicorn forming the new market, we examine the unicorn making the processes of industry category innovation through the business innovation model. Lastly, broadening the scope of the analysis to the unicorn group, policy implications in startups and venture ecosystem are suggested.

Student understanding of the nature of science is necessary not only because it is helpful for solving everyday problems with growing science literacy, but also because it influences students' science learning. Therefore, it was necessary to investigate student views on the nature of science under the 7th national curriculum and compare with those before the 7th national curriculum in order to probe the elements which contribute to changes in student views on the nature of science. A significant number of differences were found between subdimensions of views on the nature of science through the comparison. High school students under the 7th national curriculum had more relativistic, instrumental, and deductive but less process-oriented views than high school students before the 7th national curriculum. The differences between mean values which showed high school student views on the nature of science under and before the 7th national curriculum were significant, except for the subdimension of instrumentanlism/realism. In particular, high school students under the 7th national curriculum possessed a contextual view, whereas those before the 7th national curriculum possessed a decontextual view. Although other factors might be the cause for differences found in this study, we argued by discussion that differences among textbook contents seemed to be the major factor.

This study studied the life experiences of story grandmother activities on the meaning of a happy life and positive growth for the elderly through phenomenology. This study period was conducted with pre-interviews from March 2021, and research was conducted until July 2022. As for the research method, 9 elderly women were selected as a Colaizzi phenomenological research method suitable for the work of exploring and understanding life as it is, and the following conclusions were drawn. First, the happiness experience of the elderly provides a life that responds to positive changes, gives positive meaning, and actively discovers in a desire-ful life, a comparative life, and a adaptation and coping happy life. Second, the elderly experienced the meaning of life by experiencing the happiness of moments in the self-realized life of the upward · downward theory. Third, the growth of the elderly is a happy change in PERMAS of positive psychology, pursuing life with positive emotions, immersion, and positively related meaning and purpose of life, and growing while looking at life with achievement and strength. Since this study targets elderly women aged 65 or older who are engaged in story grandmother activities, there is a limit to generalizing the research results, so it is suggested to study the growth process of more diverse age groups and various types of volunteer activities in the future.
