Mt. Gamak is located south of the Imjin river, near the D.M.Z.: and the spider fauna of this area has never been explored. Tile authors collected spiders from this mountain since 1972. Findings were: 1) The authors recorded 115 species of spiders belonging to 21 families, 73 genera. including 7 undetermined spcies. 2) Trachelas japonicus was added to the fauna for the first time. Identification of Dictyna sp. (W), Episinus sp. (A) and Coeloter sp. (A) have not yet been completed by the authors. 3) These materials Iwere not sufficient for general discussion and conclusions of the spider fauna of Mt. Gamak area. However, results can be summarized: 21 northern species-$19.4\%$, 5 southern species-$4.6\%$, 1 cosmopolitan species-$0.9\%$ 4) Species common with China mainland were 45($41.7\%$). 5) As the result of this survey, the spider fauna of this area is similar to that of the Chun-cheon area, located at the same latitude in central Korea.

최근 북한지역에 발생한 홍수와 가뭄 등 심각한 자연재해의 원인이 악화된 식량난으로 인한 과도한 산림의 훼손으로 추정되고 있어 북한 지역의 산림 생태계에 대한 연구의 필요성을 더욱 확인하는 계기가 되고 있다. 위성자료로부터 얻을 수 있는 식생지수(NDVI)는 농작물, 초목, 산림등과 같은 중요한 식생자원을 모니터링 하기 위해 설계된 도구로 식생의 활력도를 정량적으로 표현할 수 있다. 또한, 식생지수는 개략적인 식생을 파악하는데 주로 사용되기 때문에 초기조사에 많이 이용되고 있다. 따라서, 본 연구에서는 개마고원지대를 포함하는 표고 1000m 이상의 한대림지대의 산림식생에 대해 9년(2000~2008)간의 시계열 MODIS영상에서 나타나는 식생지수의 생물계절 특징을 분석하였다. 식생이 성장하기 시작하는 시기(the beginning of the growing season)는 5월 9일 이후부터 5월 25일 사이의 기간으로 나타났고, 식생의 휴면 시기(the end of growing season)는 9월 14일부터 9월 30일 사이 기간으로 관측되었다. 이는 4월 초에 시작하고 10월에 사라지는 한반도의 일반적이 식생패턴보다 성장은 한달 늦게, 휴면은 한달 이르게 한다는 것이 확인되었다. 또한, 8월 초순의 NDVI 값이 9년 동안 계속적으로 가장 높은 값을 보여주고 있다. 이것은 개마고원지역 및 주변 한대림 지대는 7월 말에서 8월 초순에 식생이 가장 활발한 것을 의미한다. 9년 동안 전반적인 식생지수는 0.2~0.9 값을 보였고, 특이할 점은 9년 동안의 평균적인 NDVI 값에 비해 2002년의 식생의 활동이 봄에 빨리 개화하고 가을에 일찍 지는 패턴을 보였다.

In this paper, we propose a method for measuring the volume of packages for the efficient handling of the packages. Using the geometrical characteristics of the rectangular parallelepiped type objects, the method measures the volume of packages with one camera only in real time. In preprocessing of volume measurement, the method extracts outer lines of the object and then crossing points of the lines as feature points or vertexes. From these cross points(-feature points-), the volume of the package is calculated. Compared to the direct feature extraction, the proposed method shows especially the blurring robust result by using the line for feature extraction. Additionally, the method can get the stable result by considering object's direction. From experimental results, it is demonstrated that this method is very effective for the real time volume measurement of the rectangular parallelepiped.

Some dynamical issues about the Tsushima Warm Current (TWC) are reviewed and checked for the remaining unresolved problems, focusing on the formation of the TWC, seasonal variation of its volume transport and its branching in the East Sea. The TWC is a part of the North Pacific (NP) subtropical gyre driven by the NP global wind system. However, the quantitative amount of volume transport is sensitive to friction, basin geometry, barrier effect and so on. Among many causes suggested by many scientists, subpolar winds are found to be most closely related with the seasonal variation of TWC volume transport. However, more studies relating the latter not only to the subpolar winds but also to those including the subtropical winds seem to be required. The branching of the TWC has been known to be due to the western intensification for the East Korean Warm Current (EKWC) and to the bottom trapping for the Nearshore Branch. Since the former hypothesis is problematic in explaining the seasonal variation of the EKWC, other candidate mechanisms may need to be considered.

Drawing on costly signaling theory and self-enhancement motive, this study examines the relationships among proactive personality, knowledge sharing behavior, and organizational recognition. In addition to the individual characteristic, this study considers job characteristics as conditional factors, and especially proposes the moderated mediation model in which job complexity and variety moderate the relationships among proactive personality, knowledge sharing behavior, and organizational recognition. To prove these hypotheses, empirical analyses are conducted with 166 dyad samples collected from various industries. As predicted, individuals with high proactive personality are more likely to become involved in knowledge sharing behavior, and this behavior increases organizational recognition rated by their supervisors. Moreover, job complexity and variety moderate the positive relationship between proactive personality and organizational recognition is mediated by knowledge sharing behavior. These results reveal the motive in knowledge sharing and the boundary condition that is necessary to increase such behavior. The study findings will ultimately contribute theoretical and empirical implications to the knowledge management literature.

The Study was conducted to develope the low temperature tolerant methane-producing bacteria(LTTB) and to increase the efficiency of anaerobic fermentation for the treatment of agricultural and livestock wastes at low temperature. The samples were collected from muddy soil, water logged sediment, organic layer and anaerobic sludge at three latitudes, $34.8{\sim}37.4\;^{\circ}N(Korea)$, $41.4\;^{\circ}N(USA)$ and $54.5{\sim}56.9\;^{\circ}N(Canada)$. They were used for determination of the methanogenesis rates for isolation and identification of the LTTB. The methanogenesis rate of smaples at low temperature were higher in the cellulose medium than methanol medium. The methanogenesis rate in the samples of subarctic region were $15{\sim}19$ moles/ml during 30 days at low temperature($8\;^{\circ}C$), whereas not detected in the samples of temperate region. The methanogenesis rate in the enrichment culture of subarctic samples were inhibited by the $40\;{\mu}g/ml$ of streptomycin + vancomycin or ampicillin + oleandomycin which were not effect to the methanogens. An inhabitation of high temperature tolerant methane producing bacteria was identified in the samples of temperate region, whereas that of the LTTB growing at $8{\sim}13^{\circ}C$ was identified in the subarctic region.

Until recently, academic consensus held that Zhou Dunyi's Taijitu (Taiji Diagram) originated from Cantongqi. However, a new debate has arisen wherein some scholars question that theory and related theories. They criticize these previous theories because the books and charts used as evidence in those theories were published after the lifetime of Zhou Dunyi, and this disqualifies their influence on his thought. However, identifying certain authors as being of a slightly later period than Zhou Dunyi does not definitively answer whether or not Zhou Dunyi's diagram was based on Cantongqi. I approached this problem from a different perspective. Zhou Dunyi's Taijitu is based on the system of taiji (Taiyi), yin-yang, and the five movements. Consequently, the formation of this system should be traced back historically. In the process of tracing it back, I intended to explain that the main character of Cantongqi is closely related to the formation of the system of taiji (Taiyi), yin-yang, and the five movements. The system of taiji (Taiyi), yin-yang, and the five movements was first established as a religious theological system in the Han Dynasty. In this process, yin-yang and the five movements were combined by Dong Zhongshu, and the five movements were introduced by Han Dynasty scholars as a method of interpreting the I-ching. However, Han Dynasty scholars did not form this system. In the late Han Dynasty, Cantongqi adopted the theological system of yin-yang and the five movements to theoretically form the system of taiji (Taiyi), yin-yang, and the five movements. Cantongqi was able to form this system because of the logic that yin-yang is the essence of the I-ching. Cantongqi does not have the same schematic as Taijitu. However, the system of taiji (Taiyi), yin-yang, and the five movements appears and extracts the components that make up Taijitu. Therefore, I do not think we should hastily agree with the recent claims made by scholars.
