  • Purpose: The purpose of this study was to investigate the changing process of work activities of community health practitioners in medically vulnerable areas. Methods: For the study an historical research method was used, based on literature data and collected literature data related to the work of community health practitioners from 1940 to 2013. Results: There were 45 records according to the literature data about the work activities of the practitioners. Analysis of the process of work activities by time period was based on the historical records: first, the introduction period (1940~1980) saw the "community health practitioners begin their work activities"; second, the development period (1981~1997) involved "provision of comprehensive health and medical service"; third, the stagnation period (1998~2005) characterized by "attempts at new role changes in a crisis"; fourth, the expansion period (2006~2011) "focused on the work of health promotion"; and finally, the stable period (2012~the present) observed "work activities of community health practitioners recognized." Conclusion: Results showed five topics in the process of work activities of community health practitioners by time period. The results offer basic data to investigate work activities of these practitioners and enable discussions about the future of community healthcare.

  • Purpose: This research aims to empirically investigate the motivation of corporate voluntary disclosure by exploring the impact of historical loss on corporate social responsibility disclosure (CSRD). Research design, data, and methodology: This paper takes Chinese A-share listed firms that issued standalone social responsibility reports during the period of 2009-2017 as a sample. Drawing on extant literature, this paper defines historical loss firms as firms with net profit greater than or equal to 0 and undistributed profit less than 0. The tendency score matching method (PSM) is used to find matching samples for historical loss firms. Then OLS regression is conducted to investigate the relationship between historical loss and corporate social disclosure. Results: The results show that historical loss has a significant positive impact on the quality of corporate social responsibility disclosure. After changing the measurement of independent and dependent variables as well as adopting different matching methods to screen the control group, the results still hold. Further research indicates that the relationship between historical loss and CSRD is influenced by corporate financing constraints and industry competition. Conclusions: This research supports the resource motivation hypothesis of corporate social responsibility disclosure, and provides empirical evidence for regulators to strengthen supervision on corporate disclosure.

  • Historical control data have been shown to be valuable in the proper interpretation and validation of reproductive toxicology studies. The present data were compiled from rat fertility and early embryonic development studies conducted at Korea Institute of Toxicology during the 1994∼2001 period. These data were assembled in order to provide background information for the general and reproductive data collected in 11 fertility and early embryonic development studies using Sprague-Dawley rats obtain-ing from the Breeding Facility, Korea Institute of Toxicology, Korea. A total of 274 males and 274 females were used in these studies during the eight-year period. Parameters of fertility and early embryonic development included clinical sign, body weights, food consumption, organ weights, estrus cycle, copulation index, precoital time, fertility index, pregnancy index, sperm parameters, and early embryonic development parameters. Most of the values were comparable to the previous historical control data reported by other investigators. These data can be wed not only as a historical data base for the meaningful interpretation of data from reproductive and developmental toxicity studies, but also as a contribution to biological characterization of Sprague-Dawley rats.

  • In this study, the chukwookee data were evaluated by applying that for the historical rainfall frequency analysis. To derive a two parameter log-normal distribution by using historical data and modern data, censored data MLE and binomial censored data MLE were applied. As a result, we found that both average and standard deviation were all estimated smaller with chukwookee data then those with only modern data. This indicates that rather big events rarely happens during the period of chukwookee data then during the modern period. The frequency analysis results using the parameters estimated were also similar to those expected. The point to be noticed is that the rainfall quantiles estimated by both methods were similar, especially for the 99% threshold. This result indicates that the historical document records like the annals of Chosun dynasty could be valuable and effective for the frequency analysis. This also means the extension of data available for frequency analysis.

  • This study is on the early historical background and the process of development of modern architecture in Thai, during the period from 1782(King Rama 1) to 1934(King Rama 7). Thai started tn form a connection with western nations from the late 18C, founded the Bangkok Dynasty. Since then, Thai was increasingly influenced by western civilization and this trend included an increasing influence of western architecture. In this paper, the centeral objective is to observe the architectural change during the period from King Rama 1(1782-1809) to King Rama 7(1925-1934). This can be divided into three period. During the first period, from King Rama 1 to King Rama 3(1824-1851), Thai architecture showed a tendency to follow the preceding traditional example and to imitate Chinese architecture. The second period is from King Rama 4(1851-1868) to King Rama 5(1868-1910). During this period, Thai architectural design was increasingly influenced by western concepts, specially European Neo-classicism Style. During the third period, from King Rama 6(1910-1925) to King Rama 7(1925-1934), Thu had been enjoying extensive commerce with western nations. The great developments in the field of architecture during this reign were apparent in the construction of public utilities and facilities. These buildings were designed by western architects. At this time, modern architectural concept of western was introduced.

  • To estimate the local site effects at two town fortress areas where stone parapets were collapsed during historical earthquakes, site characteristics were evaluated using borehole drillings and seismic tests and equivalent-linear site response analyses were conducted based on the shear wave velocity (Vs) profiles determined from site investigations. The study sites are categorized as site classes C and B according to the mean Vs to 30 m ranging from 500 to 850 m/s, and their site periods are distributed in short period range of 0.06 to 0.16 sec. For site class C in the study areas, the short-period (0.1-0.5 sec) and mid-period (0.4-2.0 sec) site coefficients, $F_{\alpha}$ and $F_\nu$ specified in the Korean seismic design guide, underestimate the ground motion in short-period band and overestimate the ground motion in mid-period band, respectively, due to the characteristics showing high amplification in short period range, which can result in the collapse of stone parapets having the short natural period.

  • It is possible to divide the historical changes of slope revegetation in Japan into five periods as follows; 1) The early period after creation(1927-1948), 2) The spreading period of modern revegetation work with manpower(1947-1958), 3) The spreading period of rapid revegetation technique using exotic grasses with machineries(1959-1985${\dots}$), 4) The spreading period of rapid reforestation technique by fast growing species mainly using leguminous shrub species(1986-1995${\dots}$), 5) The developing period of nature restoration technique using endemic arborous species(1996-). Recently main purpose of slope revegetation has been developing from the erosion protection to the nature restoration in the current of the 5th period. It is said that the role of the Japanese Society of Revegetation Technology(JSRT) is critical to the history of slope revegetation in Japan. 'The tentative guidelines of slope nature restoration' was announced by JSRT in 2004. In the guidelines, it was proposed that the planning techniques of using suitable seeds/plants based on the preservation level at the each construction sites. Moreover, the use of soil seed bank is the new and important study theme in the field of nature restoration. Consequently, at present the importance of advanced monitoring methods for vegetation maintenance and plant sociologic survey to evaluate the plant succession is increasing. Finally, some critical concepts are necessary to develop the field of restoration in Korea as follows; 1) monitoring of constructed sites, 2) ensuring of biodiversity, 3) recognition of slow revegetation and mosaic arrangement in revegetation, 4) reuse and recycle on the construction sites, and 5) promotion of specialist.

A Contextual Study of the Pluralization of Sexuality Represented in Mainstream Fashion and Anti-Fashion Since the Late $19^{th}$ Century (19세기 후반 이후 주류패션과 반패션에 표현된 성의 다원화에 관한 맥락적 연구)

  • The purpose of this study is to reinterpret sexuality represented in fashion since the latter half of the 19th century in a contextual view, on the basis of Foucauldian idea of post-structural sexuality. As for research methodology, literary research was undertaken from the conception of sexuality to a historical review of the culture and dress. Foucault maintains the view of plural sexuality, which floats by power relationship between dominant and oppositional discourses in a specific historical context. In contextual approach sexual ideology codified in fashion since the latter 19C shows the following aspects: First, the traditional sexual ideology in the latter 19C is a capitalist value, which gives a priority to bourgeois man's profits, and the Victorian discourses of sexuality constructs the dichotomized fashion of the period. Next, the former half of the $20^{th}$ C is regarded as the period of conformity rather than opposition with various alternatives appropriated to the mainstream, so the traditional sexual ideology in fashion of this period is still preserved. Finally, in post-capitalism period of the latter 20C a variety of anti-fashion visualized plural sexuality from the enormous oppositional discourses. Although it doesn't all mean deconstruction of sexuality in fashion by the anti-fashion re-appropriated without oppositional meanings, pluralization of sexuality implies dynamics of sexual discourses in the next historical period. As a result, fashion since the latter 19C has been changed as a means for expressing age and sexual desire out of gender and class. And mainstream fashion in even postmodern period keeps the modern value on the center of the hegemonic heterosexual masculinity though the increase of Androgynous Femininity in women's fashion may connote the meaning of femininity. The plural sexuality represented in fashion has a contextual flexibility, thus sexuality floats with a specific socio-cultural context and fashion represents a masquerade as an identity vehicle.

  • This article examines the historical and general characteristics of science and technology policy in Korea. Historical characteristics are analyzed through formation period, growth period, and transition period. Korea institutional sis for the promotion of science and technology was made from the initial stage of industrialization. As national R&D programs were launched, technological activities in the private sector were rapidly increased from the 1980s. Korea pursued new directions of science and technology policy with the formation of related laws and Plans from the late 1990s. General characteristics are analyzed by the concept of 'policy regime'. The prime policy goal of science and technology policy in Korea has been related to industrial development so far. In the policy means, input element has been increased focusing on the external aspects. Bureaucratic policy culture has dominated other cultures including economic culture, academic culture, and civic culture.

  • Mugiyeondang(舞沂蓮塘) is the garden that the provincial noble family in Yeongnam(嶺南) has constructed since the late Joseon period. Mugiyeondang is well known as a typical case of traditional garden in Joseon period. But it is also an exceptional case because of its informal layout that infers gradual space transition. This study aims to establish the historical story of the garden beyond the superficial description about existing spatial status and literature materials. Mugiyeondang had been constructed by seven generations of the family during two hundred years, and there were significant events at every transition points. The figure and name of elements reflects each historical change of the family. Mugiyeondang is an important case to notice that a garden was not just a subsidiary space for mere leisure life of the gentry of Joseon period, But it was an important for some families as their representative and symbolic space.
