This study presents a real-time impact evaluation of a human capacity-building health project in Laos, financed by a Korean aid agency and executed jointly by Laotian and Korean higher educational agencies. The project aims to improve the health status of Laotians by enhancing practicing doctors' clinical performance capacity, to be attained by advancing academic achievement at the University of Health Sciences (UHS) in Laos. Therefore, this real-time impact evaluation adopted the difference-in-differences regression analysis method, showing that the project improved the academic achievement of the UHS students who were taught by the project fellowship awardees more, compared to the UHS students who were taught by non-fellowship faculty members. It remains to be evaluated whether these UHS students taught by the project fellowship recipients would also perform better clinically in public hospitals in the future.

The purpose of this study is to highlight the effects of the two leadership styles, namely: transformational leadership and transactional leadership, on the different types of followership through analyzing their impact in the productivity and competitiveness of human resources in IT SMEs. The paper focuses on determining whether transformational leadership or transactional leadership is more effective as shown by the levels of empowerment derived from these two types of leadership under study. From this study, alien, role model and passive types of followership, transformational leadership appears to be more influential for personal empowerment. As for group level of empowerment, the transformational type of leadership shows higher effectiveness in alien, role model, passive, and practical types of followership. On the other hand, transactional leadership yields positive impact on practical and conformist types of followership. In summary, personal empowerment plays a direct impact on group empowerment. Thus, with the exception of conformist type of followership, transformational leadership has more impact in human resources of IT SMEs.

Although the relation of caregiving burden to well-being has been frequently examined, the effect of caregiving on marital quality has been virtually ignored. The current study explores the impact of parent care on the marriages of adult children by using a nationally representative longitudinal sample. It was hypothesized that parent care would negatively influence the marital quality of adult child caregivers, the effect of parent care would differ between women and men caregivers, and the nature of marital relationship variables would moderate or mediate the impact of care on marital quality. Overall, marital quality does not appear to suffer if caregiving load is light. However, the impact of parental caregiving on some dimensions of marital quality was conditioned by gender, gender role attitudes, and congruence between attitudes and behavior.

후빙기 해수면 상승 이후 형성된 지형인 석호는 최근 인간 간섭의 증가로 인해 급격한 지형 변화가 발생하고 있다. 본 연구는 국내 석호 중 면적과 형태가 비교적 크게 변화한 청초호, 경포호, 풍호를 대상으로, 홀로세 동안에 석호와 그 일대에서 급격히 증가한 인간 간섭이 지형 변화에 미친 영향을 추론하였다. 그 결과, 인위적 변화가 급격하게 발생한 시기는 세 지역에서 공통적으로 1960~1970년대부터 시작된 것으로 확인되었고, 이후 인간 간섭이 본격화되며 지형 경관이 빠르게 변화된 것으로 나타났다. 또한 집약적 개발은 수심, 면적, 형태 변화뿐만 아니라, 수환경, 생물 다양성 측면에도 큰 영향을 미친 것으로 나타났는데, 이는 준설 및 인공구조물 설치로 담수와 해수 사이 흐름이 교란된 결과로 보인다. 마지막으로 여러 인간 간섭 유형이 복합적으로 관찰되었는데 이는 육지와 해양 환경의 영향을 모두 받는 지형 형성 과정과 관련되어 있을 것으로 보이며, 환경 조건 변화에 더하여 지형을 개발하고 이용하려는 인간 사이의 복잡한 상호작용에 의한 결과인 것으로 판단된다.

This paper examined the impacts of the regional developments and dwellers behavior on the Seacoast. Seacoast features a variety of landforms which are created by the action of waves and tidal flows. The coastal landforms are found mainly in the interface between land and sea. Although erosional landforms constitute prominent landscape features as sea stack, sea arch, and rock cliff do, it is nonetheless the depositional features such as beaches, tidal flats, offshore bars, deltas, sanddunes, and coastal plains that have various ramifications for human communities. Among these, beaches and coastal sanddunes are special in that their formation is attributable to the combined action of waves, tidal flows, and winds. The main line of discussion in this dissertation is concerned with the transformation of group of beaches sanddunes along the coastline of Chungcheong-Namdo Province. To some extent, the erosion of coastal dunes has been a global phenomenon. The degradation process occurs most actively when the spring tides attack beaches, berms, and foredunes. Also involved in the transformation of coastal dunes are factors of human agency. The extent, speed, and pattern of their morphological changes are a function of land-use pattern. The reclamation of swale and the exploitation of sands as construction material and silica sand, for example, ruin the feature of coastal dunes.

Past research shows that the construction of new infrastructure accelerates economic growth in the region by attracting more people and commodities. However, the previous studies only considered large-scale infrastructures such as sea-cross bridges and channel tunnels. There is a paucity of literature on regional infrastructure and its impact on socio-economic indicators. This paper explores the impact of new bridge construction on the human population, particularly focusing on regional bridges constructed during the 2000s in the state of Georgia. The human population at a county level was selected as a single socio-economic factor to be evaluated. A total of 124 cases were investigated as to whether the emergence of a new bridge affected the population change. The interrupted time series analysis was used to statistically examine the significance of population change due to the construction by treating each new bridge as an intervention event. The results show that, out of the 124 cases, the population of 67 cases significantly increased after the bridge construction, while the population of 57 cases was not affected by the construction at a significance level of 0.05. The 124 cases were also analyzed by route type, functional class, and traffic volume, but the results revealed, unlike large-scale infrastructure, that no clear evidence was found that a new bridge would bring an increase in the human population at a county level.

This paper focused on examining the middle school students' perceptions of characteristics(personal knowledge, human responsibility, impact on personal life, and predicted trend, behavior will) of 10 global and 8 local environmental issues. Subjects(N=516) demonstrated by completing a survey that they perceived the characteristics of issues differently on global and local scales, and to a degree those characteristics are related. First, middle school students' perceptions of global and local environmental issues were above mid-point mainly, and perceptions of local environmental issues were higher than those of global environmental issues. At perceptions of characteristics, They perceived that the personal knowledge of global environmental issues were higher than those of local issues, that the human responsibility effects on global environmental issues more than local environmental issues, that global environmental issues in the future, will be more serious. For each environmental issues, the perception of global warming among the global issues was highest, the perception of yellow dust and air pollution among the local issues was highest. For perceptions of characteristics, behavior will to solve the environmental issues was lower than that of 4 characteristics(personal knowledge, human responsibility, impact on personal life, and predicted trend). Second, there was significant difference of the perceptions of two scale environmental issues for area and sex. It showed that Seoul students' perceptions were higher than Kong-ju students' perceptions according to area, and that girl students' perceptions were higher than boy students' perceptions according to sex. Third, correlations among issues were significant. Especially, it was positive relationship between knowledge and human responsibility, human responsibility and impact on personal human responsibility and predicted trend. Educators and communicators should take into account the perceived characteristics of environmental issues and choose effective information sources and teaching methods to improve students' understanding of human-induced environmental changes.

Scientific evidence shows that ambient air quality is one of the major environmental issues related to human health. The aim of this paper was to provide quantitative data on the short-term impact of air pollution on the mortality and morbidity of people living in Suwon city. There are some studies that have conducted health impacts of the air pollution in Seoul, Korea. However, there are few studies of the health effects on air pollution conducted in satellite cities of the Seoul Metropolitan area. For this reason, we investigated the health effects of air pollution in Suwon city, one of the highly populated satellite cities of Seoul. In order to estimate the short-term mortality impact of air pollution, this study applied the approach suggested by the World Health Organization (WHO), using AirQ2.2.3 software. Daily concentrations of $PM_{10}$, $O_3$, $NO_2$, and $SO_2$ were used to assess human exposure and health effects, in terms of attributable proportion of the health outcome, annual number of excess cases of mortality for all causes, and cardiovascular and respiratory diseases. Among the four considered air pollutants, $PM_{10}$ had the highest health impact on the 1,118,000 inhabitants of Suwon city, causing an excess of total mortality of 105 out of 4,254 in a year. Sulfur dioxide had the least health impact. Ozone and nitrogen dioxide each caused 42.7 and 81.3 excess cases of total mortality in a year. The results are also in line with those of other international studies that apply AirQ software.
