The purpose of this study was to chronologically review the public records management policies in Korea, and get some perspectives for their sustainable growth in the future. In this study, the period of 60 years since the establishment of the First Republic in 1948 was divided into six parts; inception period(1948~middle of 1980s), preparation period(end of 1980s~1990s), development period (2000~2007), and transition period(2008~present). The achievements and failures of public records management in each period were summarized. A diagnosis of present situation of Korean public records management was made. And adopting a bi-directional networking model was suggested in order to convert into a new revitalizing period.

Under current design standard, sewers are designed to drain stormwater generated up to 10 year return period of storms. This implies sewer flooding could occur from rainfall exceeding a 10 year return period. 5, 10, 20 and 30 year return period of storm intensities were calculated for 22 locations (cities) of meterological stations over the nation and compared to the recorded rainfall intensities for the last 30 years. The comparison resulted in the numbers of year maximum rainfall intensities exceeded each return period. Using the questionnaire survey for "the incidences of flooding since 1980" of the previous paper (Survey on sewerage operation/management planning for flooding (I)), the actual rainfall records on the date of flooding events were analyzed to demonstrate the number of flooding events caused by the exceedance of sewer capacity. For the last 30 years, more than 6 years of year maximum rainfall intensity (20%) were larger than the 10 year return period of storm in 4 cities of the 22 used for the first analysis. The number of rainfall records that exceeded the 10 year return period was 50 of the 260 actual flooding events investigated from the survey.

The popular edition of "Hwangjenaegyeong somun(黄帝内經 素問)" was established by Wangbing(王冰)'s revising and annexing notes in the Dang(唐) Period. He revised "Jeonwongibon(全元起本)" which became the edition we currently know widely. To know how "Somun(素問)" had been handed down from the Su(隋) Period to the Dang(唐) Period before the establishment of Wangbing(王冰) 's edition, we reviewed the citation of "Somun" in the four books: "Ohaengdaeui(五行大義)", "Jebyeongwonhuron(諸病源候論)", "Sagijeong-ui(史記正義)", and "Oedaebiyobang(外臺秘要方)". As a result, it has been discovered that even if the reference was written as "Hwangjesomun(黄帝素問)" or "Somun(素問)", they did not correspond with the currently established "Somun(素問)" in many cases. On the other hand, there were identical sentences to the current "Somun(素問)" among the cited parts; whereas "Yeolron(熱論)" and "Jahakron(刺瘧論)" were often cited in the medical books such as "Jebyeongwonhuron(諸病源候論)" and "Oedaebiyobang(外臺秘要方)", "Yeolron(熱論)" and "Jahakron(刺瘧論)" were often cited. Thus, we can suggest that the relevant content of "Somun(素問)" should be considered important in the period in question and further that the concept of disease symptom might have changed in those days.

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.

In order to verify the feasibility of expansion of back-fire limit equivalence ratio in the hydrogen-fueled engine with external mixture, the characteristics of performance and combustion are experimentally analyzed with change of intake/exhaust valve timings under the fixed valve overlap period of $0^{\circ}$ CA(non-valve overlap period). These characteristics are also tested for the change of exhaust valve closing timing while intake valve opening timing is fixed to clear the main cause of back-fire occurrence. As the results, the less valve overlap period center is retarded, the more back-fire limit equivalence ratio increases and back-fire does not occurred after TDC. In addition, it was shown that the control of back-fire is dependent on intake valve opening timing than valve overlap period.

This study was aimed at analyzing the woman costume presented in the korean modern novel by continuity, mixture, and discontinuity. For the costume analysis, the korean modern novel written from 1910 to 1945 were used. The results of this study were as follows: 1. Continuity: It doesn't mean discontinuity from the past but succession and development of the past, which explains about the costume culture for the period from 1910 to 1919. During this period, people tended to wear korean traditional costume in an effort to maintain their national identity. 2. Mixture: It means the effort to synthesize and develop past, present and future, which explains about the apparel for the period from 1920 to 1937. During this period, western culture was introduced much into korea to be established as part of our people's life. The new generation of women who studied abroad introduced the western costume throughout the cities, while the convenient western costume served to improve korean traditional costume. 3. Discontinuity: It means a conscious departure from the past as well as a critical reaction to the past, which explains about the costume culture for the period from 1938 to 1945. For this period, western costume was popular among new generation of women, while it was more diversified with increasing population wearing them. Many country men and women proceeded to wear the western costume.

Brief history of home economics education after modern period (GAEWHA-KI) (1900~1945). Education of home economics in our country is known to have been developed mainly through school education by need of women education. The first period is construed "from 1890's until before the conclusion of ULSABOHO treaty, which can be referred to as an inception of the education for home economics by including subjects of sewing and manual arts in the curriculum of EWHA-hakang. The second period is "from the conclusion of ULSABOHO treaty in 1905 until the act of higher education for women was decreed, transition of the education for home economics and major curriculum thereof and the text books of home economics are handled. The third period is "from the promulgation of CHOSUN education act in 1911 until the fall of Japan education of home economics in this period is described in terms of national education under the Japanese colonial rule. The education was first renewed by women missionaries with the onset of "blooming period (GAEWHA-KI)" and school education of home economics far educating women was initiated at EWHA-hakdang in 1896, in 1908, with the pronulgation of the act of higher education for women, major curriculum and subjects were set up and text books of home economics were also compiled. In accordance with CHOSUN education act in 1911, housekeeping and sewing subjects at secondary school were taught 10 hours a week with the emphasis on general education and practical subject oriented training. Home economics under the Japanese rule was so educated as to imbue, students with the sense of nationality by teaching Korean custom and family habits.

This study is designed for examining the names of men's and women's clothing of Choseon period, which can be divided into the upper, the lower, and the outer garments based on yu유, go고, po포 from the early period. Furthermore, amongst these various garments, this study shall define some kinds of clothing, which is shared its name and its use by both men and women, as the unisex clothing. Lastly we analyzed the special characteristics of this unisex clothing. With the names of clothing in Choseon period, we could understand about the difference of clothing's development by the names for the upper, lower, and outer garments as gender. And we also found the names for the unisex clothing in that period. The names of unisex clothing in Choseon period can roughly be divided into three garments; the upper, the lower, and the outer. Each category can also be subdivided into tku: i. e. the upper garments into jeogori저고리, hansam한삼, sama 삼아, jeoksam적삼, donguidae동의대, and godo고도; the lower garments into go고, gonja고자, and baji[paji파지, pachi파저］; and the outer garments into jangui장의, baeja배자, and juui주의. Furthermore, we can recognize that the shapes and uses of clothes in that period had been represented differently between the men's and women's.

In the circuit model that outputs are latched and input vectors are successively applied at inputs, the gate resizing approach to reduce the delay of the critical pathe may not improve the performance. Since the clock period is etermined by delays of both long and short paths in combinational circuits, the performance (clock period) can be optimized by decreasing the delay of the longest path, or increasing the delay of the shortest path. In order to achieve the desired clock period of a circuit, gates lying in sensitizable long and short paths can be selected for resizing. However, the gate selection in path sensitization approach is a difficult problem due to the fact that resizing a gate in shortest path may change the longest sensitizable path and viceversa. For feasible settings of the clock period, new algorithms and corresponding gate selection methods for resizing are proposed in this paper. Our new gate selection methods prevent the delay of the longest path from increasing while resizing a gate in the shortest path and prevent the delay of the shortest path from decreasing while resizing a gate in the longest sensitizable path. As a result, each resizing step is guaranteed not to increase the clock period. Our algorithmsare teted on ISCAS85 benchmark circuits and experimental results show that the clock period can beoptimized efficiently with out gate selection methods.
