Minutes of the state council are the highest level records which can show the overall decision making process at the state level. The purpose of this study is to suggest the methodology for designing historical contents based on relational structure of minutes of state council and records of ministries in the period of Rhee Regime. The methodology has three steps; first, it suggests directions of DB design that represent the basic information and agenda of the state councils through the period of Rhee Regime. Second, it proposes subject classification scheme for major policy matters in the period. to which each agenda will be assigned and related ministries' records will be linked. Third, it suggests the basic structure and procedures to develop the historical contents on each subject matter based on the minutes and relational records of ministries.

Seasonal distributions of nutrients and particulate organic matter were investigated in Asan Bay, Korea. Most of nutrients were high in August and low in February. The atomic ratios of inorganic nitrogen to phosphorous were close to Redfield ratio except in May when the ratio was 24.8. In May, nutrient concentrations except phosphorous decreased with salinity until $31.5{\sim}32.0%0$, but the concentrations increased again with salinity, impling that there were nutrient input sources within the estuary. Howerer, significant inverse relationships between nutrients and salinity in August suggest that nutrient sources were river discharge. Maximum chlorophyll a concentrations occurred in May. Relatively low ratios of $R_b$ to $R_a$($R_b$: fluorescence before acidification; $R_a$: fluorescence after acidification) during the study periods indicate that phytoplankton were not in good physiological condition. Relatively low ratio of particulate biogenic silica(PBSi) to particulate organic carbon(POC) and high ratios of PBSi and POC to chlorophyll a during the study periods suggest input of non-living detrital PBSi and POC from bottom in Asan Bay, where strong tidal mixing occurs.

This paper empirically investigates the dynamics of the poverty-higher education gap in Korea. Poverty may lead to a gap in access to higher education through two channels: the short-term inability to pay college tuition and fees and long-term disadvantages arising from one's environment that impede the development of academic ability. A regression analysis based on data from the Korean Education and Employment Panel suggests that it is long-term disadvantages that plays a dominant role in the dynamics of this gap. We also replicate a study carried out by Carneiro and Heckman, who have addressed a similar question in the US. Again, the results confirm that the crucial constraint is the long-term accumulation of disadvantages arising mainly from family background, not the short-term constraint. These findings suggest that policies designed to alleviate short-term financial constraints, such as tuition reduction, will be less effective in reducing the gap in accessing four-year college in Korea than policies involving early intervention in children's development.

Kim Yoo-shin was highly evaluated in Silla, not only when he was alive, but also after his death. When he was alive, he was regarded as one of the best servants who accomplished the task of 'Iltong-Samhan' by supporting KiIng Tae-jong and King Mun-mu. Kim Yoo-shin was recognized as 'good servant' or 'sacred servant' who helped King Tae-jong even after he died. In addition, he was revered as 'two adults' with King Mun-moo. He was awarded the title of 'The Great King Heung-mu'. In the Goryeo period, it was supported as a national sacrifice in the shrine of Mt. Taeryeng of Jinchon. Kim Yoo-shin was regarded as a person who achieved great success with the absolute trust of King Tae-jong and King Mun-mu. In addition, Yoon-gwan recognized Kim Yoo-shin as a general who caused many miracles. Lee Seung-hyeo said that Kim Yoo-shin had a mysterious Military-Strategy Book and excelled in martial arts. Even during the Joseon Dynasty, the evaluation of Kim Yu-shin's success had been continued due to the absolute trusting relationship between King Taejong or King Mun-moo and his retainer Kim Yoo-shin. Kim Yoo-shin was either the representative of Silla's martial or the most outstanding figure in the entire history of the Silla Dynasty. Furthermore, he was recognized as a person with competence and aptitude comparable to Chinese characters. Kim Yoo-shin was superior in military strategy. Kim Yoo-shin was evaluated as a representative of martial in Korea's history. From a neo-Confucian point of view, they evaluated him as a loyal person through Kim's achievements.

This study was conducted to obtain basic informations for breeding and improving cultural practices of sesame (Sesamum indicum L.) through investigation of several agronomic characters of 82 major varieties plants in April 20, May 15 and June 20. Stem diameter and plant height were largest in early planting(April 20). On the contrary, they were smallest in late planting(June 15). Therefore, the later planting, the poorer the vegetative growth on the basis of stem diameter and plant height. Number of capsules per plant and number of grains per capsule were 88 and 54, respectively, in the early planting, while they were decreased to 25 capsules and 40 grains in late planting. The percentage of ripeness and 1000 grain weight 78 and 2.3g in the April 20planting while they were 58% and 2.1g in June 20 planting indicating the later planting, the lower the ripeness. Grain yield per m1 in April 20 and June 20 planting was 112 and 18g respectively. Consequently, grain yield significantly decreased as planting delayed. On the basis of the vegetative and reproductive growth, varieties could be classified into early, conventional, late and indetermediate planting adapted groups. The major yield components were highly and postively correlated with accmulated sunshine hours and temperatures confirming that grain yield was closely related with sunshine and temperature. Among the varieties tested, Gurye and Local 135 had more than 150 capsules. Haenam and Woogang had more than 75 grains per capsule. Since grain yield oflate planted sesame were significantly different among the varieties, breeding of sesame for after barly cropping would be more effective under late cultural condition of after barly.

In this paper, the possibility of arc tracking, caused by combustion at the circuit breaker, was discussed. The arc tracking, occurred at the source terminals of all the circuit breakers, when we burned electric leakage circuit breakers with 220V applied. We had a same results of the experiment to simulate fire scene, in the circumstance of fire, all of the circuit breakers had arc tracking caused by combustion. Therefore we confirmed that the arc tracking at the source terminal of circuit breaker could be occurred by just combustion in the fire scene, and it was impossible to decide the cause of fire for reason of discriminating arc tracking at the terminals of circuit breaker.

Until now, archives of colonial era preserved in each public institution including National Archives & Records Service can be called as the results of colonial chosun government general's records management activities. However, it is a fact that only the fragment of the archives from colonial era remained in public institutions without maintaining integrity of record. Therefore, it is virtually impossible to restore operations process of the era only with current records. It is somewhat because some records were institutionally abrogated by valuation selecting standard of colonial chosun government general, but it is more likely the result of systematic destruction of documents and records upon liberation. On the other hand, although records that were being preserved by colonial chosun government general's acquisition policy escaped the systematic abrogation, the scope and target of the historical records were changed according to acquisition policy. Historical records managed by each inquiry agency of colonial chosun government general were collected to be used for fundamental information of colonial rule or compilation of Chosun history. However, archives collected by colonial chosun government general could not escape partiality as a goal for colonial rule had priority over the standpoint for recording Korean society. Although records management system of colonial chosun government general was introduced from Japanese government's system, it clearly shows colonial characteristics in the process of collecting Chosun's historical records and its use.

It is encouraging fact that people are more interested in collecting modern archaic art objects of Korea with broadening spectrum of research these days. For the research in this area is significant in that it makes us learn the level of collection and appreciation which were prevalent at the end of the Josen Age by trend of preferring Occidental pictures as well as modern change in the form of collection, and enables us to reconstruct the history of modern art objects in East Asia. Except Jeon, Hyung-Pil(全鎣弼: 1906-1962), the modern collectors of Korea were not studied in details with respect to the course or contents of collection. Besides Jeon, Hyung Pil, the main modern collectors of Korea were Park, Young-cheol(朴榮喆: 1879-1939), Kim, Yong-jin(金容鎭: 1882-1968), Ham, Seok-tae(咸錫泰: 1889-?), Kim, Sung-soo(金性洙: 1891-1955), Choi, Chang-hak(崔昌學: 1891-?), Jang, Taek-sang(張澤相: 1893-1969), Kim, Chan-young(金瓚泳: 1893-?), Lee, Han-bok(李漢福: 1897-1940), Park, Chang-hun(朴昌薰: 1898-1951), Baek, In-je(白麟濟: 1898-?), Lee, Byung-jik(李秉直: -1973), et al. The object of this publication in serial form is to trace and identify the life, collected articles and contents of collection of Korean collectors who intensively collected archaic art objects in the modern age of Korea, especially, under the rule of Japanese imperialism. The first person to be introduced in this publication in serial form is Jang, Taek Sang, a leading figure in the political history of Korea. Born as the son of wealthy man, he ascended to the position of prime minister, leading a dramatic life. Being a distinguished orator, Jang, Taek Sang was well known as an appreciator and collector of picture, calligraphy and pottery. As one of the collectors of main cultural property under the rule of Japanese imperialism, Jang, Taek Sang collected countless distinguished heritages, most of which were lost during the Korean War. As he became a candidate for president to compete with Lee, Seung Man later, he sold main heritages. Thus, nearly all of the collected articles were scattered.

Since more than 50${\%}$ of annual precipitation in Korea falls during Changma, the rainy season of early summer, and Late Changma, the rainy season of late summer, forcasting the onset days Changmas, and the amount related rainfalls would be necessary not only for agriculture but also for flood-control. In this study the authors attempted to build a prediction model for the forecast of the onset date of Changmas. The onset data of each Changma was derived out of daily rainfall data of 47 stations for 30 years(1961~1990) and weather maps over East Asia. Each station represent any of the 47 districts of local forecast under the Korea Meteorological Administration. The average onset dates of Changma during the period was from 21 through 26 June. The dates show a tendency to be delayed in El Ni${\~{n}}o years while they come earlier than the average in La Nina years. In 1982, the year of El Ni${\~{n}}o, the date was 9 Julu, two weeks late compared with the average. The relation of sea surface temperature(SST) over Pacific and Northern hemispheric 500mb height to the Changma onset dates was analyzed for the prediction model by polynomial regression. The onset date of Changma over Korea was correlated with SST in May(SST${_(5)}{^\circ}$C) of the district (8${^\circ}$~12${^\circ}S, 136${^\circ}~148${^\circ}W)of equatirial middle Pacific and the 500mb height in March (MB${_(3)}$"\;"m)over the district of the notrhern Hudson Bay. The relation between this two elements can be expressed by the regression: Onset=5.888SST${_5}"\;"+"\;"0.047MB${_(3)}$"\;"-251.241. This equation explains 77${\%}$ of variances at the 0.01${\%}$ singificance level. The onset dates of Late Changma come in accordance with the degeneration of the Subtro-pical High over northern Pacific. They were 18 August in average for the period showing positive correlation(r=0.71) with SST in May(SST)${_(i5)}{^\circ}$C) over district of IndiaN Ocean near west coast of Australia (24${^\circ}$~32${^\circ}$S, 104${^\circ}$~112${^\circ}$E), but negativ e with SST in May(SST${_(p5)}{^\circ}$ over district (12${^\circ}$~20${^\circ}$S,"\;"136${^\circ}$~148${^\circ}$W)of equatorial mid Pacific (r=-0.70) and with the 500mb height over district of northwestern Siberia (r=-0.62). The prediction model for Late Changma can be expressed by the regression: Onset=706.314-0.080 MB-3.972SST${_(p5)}+3.896 SST${_(i5)}, which explains 64${\%}$ of variances at the 0.01${\%}$ singificance level.
