Objective: The objective of this study was to define the Dynamic Sitting (DS) through trend analysis and research on the Dynamic Chair (DC) and applied technologies. Background: The effects of changing posture on the human body have been studied to find out healthy sitting postures. It is believed that changing posture is effective in reducing disc pressure on spinal cord and preventing back pain and musculoskeletal disease. But, the definition of DS and trends of DC have not been researched yet. Therefore, trend analysis of DC and its applied technologies are required to define dynamic sitting posture. Method: We researched the type of occupant postures from previous studies. And then, sitting behaviors were classified into three types; (1) sitting and standing, (2) working and studying, (3) taking a rest. Results: Variety shapes of DC and applied technologies were found out. From the result, the trend of DC and applied technology were summarized from three perspectives. ; (1) changing the chair functions according to user's intention, (2) conversion of dynamic chair technologies to office chair mechanism, (3) enables the user to change their sitting posture without operating control device. Conclusion: From this study, we defined dynamic sitting posture and analyzed the trend of DC and its applied technologies. This result might be used to develop an office chair for healthy sitting. But further investigation is required to figure out the technologies and functions for development of healthy chair. Application: The results of the publishing trend analysis might help to determine design concept of office chair.

This study analyzed Korean middle-aged men's fashionable styles according to ageless trends as their representative characteristic and deriving their special features from men's magazines. Literature and case studies were conducted together. The research findings are as follows. First, it showed uniformity, conformity, passive clothing selection and consumption in 1990s as characteristics of middle-aged men's wear by period. However, clothing became an expressive way to pursue individuality and an ageless trend gradually, and middle-aged men positioned themselves as subjects of a consumer market for men's wear after 2010 through active clothing selection and consumption. Second, along with a trend change preferring a comfortable and active to formal atmosphere, it showed that casual style became diversified and segmented gradually in Korean middle-aged men's ageless trend and fashionable style. Third, as for formative characteristic changes in middle-aged men's fashionable style by period, it contained a slim silhouette, bright and splendid colors and patterns, increase of light, active and functional materials, generalization of casual items and pursuit of individuality by various mix & match styles. Fourth, in Korean men's ageless trend and changing fashionable style, four kinds of special characteristics were derived that included a change of the traditional clothing symbolism, weakened conformity & pursuit of personality, obscured boundaries between age and wearing style, and active embracing of a trend.

There is only limited evidence for the association between fruit and vegetable consumption and mental health in Korea. This study examined the relationship between fruit and vegetable consumption and mental health according to physical activity among Korean adult women. Based on data of the Korean National Health and Nutrition Examination Survey (2014-2016), a total of 5,332 participants were included in this analysis. With increasing fruits and vegetables consumption, the prevalence of depressive mood was significantly decreased (p for trend=0.0248). The prevalence of stress perception (p for trend=0.0422) and the prevalence of depressive mood (p for trend=0.0300) were decreased with increasing fruit consumption. The prevalence of depressive mood was significantly decreased when fruit and vegetable consumption (p for trend=0.0370) and fruit consumption (p for trend=0.0356) were increased for those Korean women with low intensity of physical activity. For the obesity group (Body mass index 25 kg/㎡), the prevalence of depressive mood was decreased with increasing fruit and vegetable consumption (p for trend=0.0111) and increasing fruit consumption (p for trend=0.0165). In conclusion, fruit and vegetable consumption were associated with mental health according to physical activity among Korean adult women. Further prospective studies are warranted to explore the association between fruit and vegetable consumption and mental health among Korean adult women.

Advance development of the internet has brought significant changes to the distribution structure of the fashion industry, resulting in decreased sales in Road shops and sudden growth of online fashion specialty shopping malls. As detailed analysis on internet fashion shopping malls is necessary in order to make a future projection on changes in the fashion industry, this thesis aims to study the color, fabric / pattern, silhouette, item / detail, image, etc of 2008 S/S apparel fashion style sold in the top ten shopping malls, selected in terms of sales volume and awareness. The results were further analyzed to characterize each individual shopping malls, upon which the design was compared with the five main trends for the season provided by three fashion research agencies in order to study the level of trend acceptance. Studies showed that 'Romantic Sake' trend was most widely accepted, followed by 'Eco Nature' which most reflected the characteristics of Spring. 'Modern Ethenic' trend was most aggressively accepted at more upscale shopping malls targeting older demographic, while " Play Urban' was highly accepted by shopping malls specializing in young casual. Due to the disadvantage of not being able to try on the items before purchase, styles following the 'City Luxe' trend featuring fitted suits showed the lowest trend acceptance. Amongst the design elements, color was most widely accepted.

구간별 상수 구조를 가지는 관측값으로부터 변화점을 식별하기 위해 FLSA가 자주 사용되고 있다. FLSA는 총변동벌점을 이용하기 때문에 평균 수준이 단조성을 가지는 경우에는 변화점 식별에서의 일치성이 보장되지 않는다는 특징이 있다. ℓ₁ 추세필터는 오차제곱합과 기울기 차이에 대한 ℓ₁ 벌점의 합을 목적함수로 가지는 구간별 선형 구조 추정방법으로 구간별 선형 구조에서의 변화점을 식별하기 위해 활용할 수 있다. 한편, ℓ₁ 추세필터의 경우에도 총변동벌점을 이용하므로 FLSA와 마찬가지로 변화점 식별에 있어서 비일치성을 보일 것으로 예상할 수 있는데 이와 관련된 연구는 아직까지 많이 이루어져 있지 않다. 이 연구에서는 모의실험을 통해 구간별 선형 모형에서 변화점을 식별하기 위해 사용되는 ℓ₁ 추세필터의 비일치성에 대해 살펴본다.

Objectives: Even though experimental studies have suggested that iron can be involved in generating oxidative stress, epidemiologic studies on the association of markers of body iron stores with cardiovascular disease or cancer remain controversial. This study was performed to examine the association of serum ferritin and transferrin saturation (%TS) with all-cause, cancer, and cardiovascular mortality. Methods: The study subjects were men aged 50 years or older and postmenopausal women of the Third National Health and Nutrition Examination Survey 1988-1994. Participants were followed-up for mortality through December 31, 2006. Results: Serum ferritin was not associated with all-cause, cancer, or cardiovascular mortality for either men or postmenopausal women. However, all-cause, cancer, and cardiovascular mortality were inversely associated with %TS in men. Compared with men in the lowest quintile, adjusted hazard ratios for all-cause, cancer, and cardiovascular mortality were 0.85, 0.86, 0.76, and 0.74 ($p$ for trend < 0.01), 0.82, 0.73, 0.75, and 0.63 ($p$ for trend < 0.01), and 0.86, 0.81, 0.72, and 0.76 ($p$ for trend < 0.01), respectively. For postmenopausal women, inverse associations were also observed for all-cause and cardiovascular mortality, but cancer mortality showed the significantly lower mortality only in the 2nd quintile of %TS compared with that of the 1st quintile. Conclusions: Unlike speculation on the role of iron from experimental studies, %TS was inversely associated with allcause, cancer and cardiovascular mortality in men and postmenopausal women. On the other hand, serum ferritin was not associated with all-cause, cancer, or cardiovascular mortality.

Many scientists today say that converged technologies, not specifically dedicated technologies, will be in the vanguard in the $21^{st}$ century. Technological Convergence is the merging of different areas of technology to perform similar tasks. Since we are living in the era of Technological Convergence, it is time for us to think about how to cope with the daily demands we are facing in science parks. Technological Convergence is a mega trend in commercial areas today but, so far, no science parks seem to have tried to reshape their management policies or programs in order to utilize this trend. For the development of science parks we suggest some tasks such as: identify potentials for Technological Convergence, establish a convergent ecosystem by building connections across stove-piped systems, effect a technological convergence platform, and conduct further research for strengthening plans for converging technologies.
