A study on the root-knot nematodes (Meloidogyne spp.) affecting economic crops in Korea was undertaken to know the distribution of the nemic fauna. Total 66 samples were taken from soil and root of 24 host plants at different localities in 4 provinces. Four Meloidogyne species such as Meloidogyne hapla, Meloidogyne arenaria, Meloidogyne incognita and Meloidogyne javanica were identified and some morphological characteristics were described. One of these, Meloidogyne javanica was reported newly in Korea from Horticultural Experimental Station, Suweon, Gyeong Gi on potato, Geomsadong, Daegu on chinese cabbage, Sangeogdong, Daegu, Gyeong Bug on violet and Choeumri, Namhae, Gyeong Nam on pumpkin. In Jae Ju province, Meloidogyne incognita was only found except the other three species. The most common and widely distributed Meloidogyne species in Korea is Meloidogyne hapla by $50\%$ in total, next Meloidogyne incognita $33.3\%$ Meloidogyne arenaria $10.6\%$ Meloidogyne javanica $6.0\%$ in turn, The root-knot nematodes infected the most severely in Jae Ju province and Gyeong Nam, Gyeong Bug and Gyeong Gi province in turn. Twenty four plants were attacked by root-knot nematodes among them important economic crops are soybean, peanut, potato, tomato, cucumber, carrot, pumpkin, wateremelon, edible burdock, pepper, eggplant, cabbage, lettuce and tobacco in Korea.

At the archaeological site, there are a variety of fired soil remains with which archaeomagnetic dating is measured, and there are also different kinds of kilns equipped with favorable plasticity conditions, so quality data can be gained. Among them, roof tile kilns indicate fairly great results of archaeomagnetic measuring. This should be associated with the properties of soil consisting of the kilns. With a lot of experimental results, it has been found that the fired soil samples of roof tile kilns have formed very stable residual magnetization. This author conducted archaeomagnetic research to present archaeomagnetic results of measuring about roof tile kilns from Goryeo in Gyeonggi. With the archaeomagnetic data of measuring 21 samples, this researcher tried to estimate the archaeomagnetic dating of roof tile kilns from Goryeo in Gyeonggi and divided them into three groups, group A (A.D.900~1150), group B (A.D.1150~1250), and group C (A.D.1300~1400) to figure out their relative order and arrange them in order. Through this kind of archaeomagnetic research, it will be possible to identify the dating of 21 roof tile kilns from Goryeo in Gyeonggi and also contribute considerably to chronological research on roof tile kilns from Goryeo. In the body, the remains and kilns belonging to each group are presented in detail.

The purpose of this study is to provide fundamental heating design data for the large public enclosures as gymnasium. This study executed indoor thermal environment verification of the existing gymnasium by measuring temperature distribution with and without heating the space in winter. Heating loads from human body was not considered. We examined various indoor thermal environment factors of the large enclosed space in this study which include vertical and horizontal temperature distribution, supply and return air flow feature, thermal comfort environment feature, amount of ventilation and etc.

The object of this research is to analyze the impact of the four dimensions of on-line game attributes, challenge, social interaction, entertainment and actuality, on customer satisfaction and loyalty. At the same time, mediating effects of switching barriers, such as switching cost and attractiveness of alternatives on the relationships between customer satisfaction and customer loyalty are also analyzed. The results showed that the challenge, social interaction, entertainment had significant effects on customer satisfaction. Customer satisfaction also effected customer loyalty. Another important result is that switching cost and attractiveness of alternatives played an intermediating role between customer satisfaction and customer loyalty.

문제: 영상의학과 특수 검사(CT, MRI, 초음파)가 고가인 것에 반해 환자의 대기시간이 길어 환자의 만족도가 낮고 부도율(non-attendance rate)도 높다. 목적: 환자의 영상의학과 특수 검사 예약률과 부도율(non-attendance rate)을 파악하고 이에 관한 원인을 분석하여 환자의 만족도를 증가시킬 방안을 모색하는 것이 목적이다. 의료기관: 경기도에 소재한 920병상규모의 대학병원 질 향상 활동: 영상의학과 검사 예약 환자의 부도율 원인 조사 및 만족도 조사를 실시하여 원인을 파악하고 개선을 통해 질 향상을 도모하였다. 개선효과: 전체부도율이 개선 전 9.6명에서 개선 후 7.1명으로, 불량률은 개선 전 10.43%에서 개선 후 7.81%로 다소 감소되었으며 검사 예약률은 개선 전 93.94%에서 개선 후 94.51%로 미 예약률은 6.0%에서 5.5%로 감소하였다.

Diverse endophytic fungi were isolated from surface-sterilized leaves of three species of conifers inhabiting various sites in Korea: Abies nephrolepis, Pinus koraiensis and Taxus cuspidate. The isolates were identified based on morphological characteristics and sequences analysis of both internal transcribed spacer and large subunit regions of rDNA. In this paper, we report on five previously unreported species of endophytic fungi isolated from conifers: Biscogniauxia maritime, Nemania diffusa, Pezicula carpinea, Phomopsis juglandina and Sydowia polyspora.

We reported that an alien species of Plantaginaceae, Plantago aristata Michx. from North America, grows at the Han-River estuary in Go-Yang City, Kyunggi Province. This species is easily distinguished from others in Korea by its linear leaves, cylindrical spikes with long linear bracts at base, and relatively large flowers of ca. 4-6 mm in diameter. We called the species as gin-po-ggot-jil-kyung-i as a local name. Plantago aristata is known to be very invasive and has been already introduced to Japan and China.

Some hydromedusae were collected from Shiwhaho (Kyonsgi-do), Korea Strait and Yeosu, Korea during years 2000-2002. They were identified into Sorsia tubulosa (M. Sars, 1835) of the order Anthomedusae, and Liriope tetraphylla (Chamisso and Eysenhardt, 1821) of the order Trachymedusae respectively. They are new to the Korean fauna. The order Trachymedusae is first recorded in Korea. The long tube-like manubrium and four marginal tentacles are characteristics of S. tubuloso. In L. tetraphylla, the four triangle-shaped gonads and their positions upon half of surface of subumbrella, the seven blind centripetal canals in a quadrant and the long fat manubrium are its distinct characteristics. Resulting from this work, the Korean hydromedusae identified so far consist of 13 species of 11 families in five orders.
