Objectives : To clarify clinical features of panic disorder and to compare the characteristics of cognitive patterns, avoidance behaviors, and coping strategies among patients who have panic disorder with or without agoraphobia. Methods : Family backgrounds, cognitive patterns in the first panic attack, coping strategies, and avoidance behaviors were compared among the three groups classified by panic patients with mild agoraphobia(mild PDA=66), severe agoraphobia(severe PDA=71), and without agoraphobia(PD=21) Results : 1) Severe PDA reported significantly high panic attack frequency and more dysfunctional level than PD. 2) Catastrophic thinking of 'dying' in PD was significantly frequent than the other groups. Other fears of 'going craze or loss of control' in severe PDA were the highest among the three groups, though it was not significant. Specific thinking process or interpretation in the first panic attack was not significantly different among the three groups. 3) As avoidance behaviors became worse, the frequency of avoidance behaviors and the patters of avoidance behaviors increased. Conclusions : The results suggested that as avoidance behaviors became worse, the frequency of panic, maladaptive functioning and the patterns of avoidance behaviors increase. This might be why we need to decrease avoidance behaviors through exposure as the treatment.

우리 나라 동해안에 위치한 화진포에서 채집된 요각류, Paracyclopina nana의 생물학적 특성을 알아보기 위하여 각 유생 단계의 탈피율 및 탈피에 소요되는 시간을 알아보았다. 수온 20℃, 염도농도 17ppt의 조건에서 T. suecica를 먹이로서 충분량 급이 했을 때 P. nana의 어미로부터 갓 부화되어 나온 nauplius 유생은 성체가 되기까지 평균 17일이 소요됨을 알 수 있었다. 특히 제 1 nauplius 유생 단계에서 제 2 nauplius 유생으로 탈피하는 데에 평균 3.3일이 소요되어 가장 많은 시간을 요하는 것으로 나타났다. 점차 탈피하는데 소요되는 기간은 짧아져서 제 5 nauplius 유생 단계에서 제 6 nauplius 유생 단계로 탈피하는데에 가장 짧아서 약 1일이 소요되었고, 제 2 copepodid 유생 단계에서 제 3 copepodid 유생 단계로 탈피하는데 약 2.5일이 소요되었다. 한편, 제 1 nauplius 유생 단계에서 제 2 nauplius 유생 단계로의 탈피율은 66.7% 그리고, 제 6 nauplius 유생단계까지의 탈피율은 50%를 나타내었다. The moulting rate and inter-moult interval(days) of each larval developmental stages of Paracyclopina nana were studied. The copepod, P. nana was collected from lagoon Hwajinpo, South Korea. The experimental conditions were temperature 20℃, salinity l7ppt and fed on micro-algae, Tetraselmis suecica. The species was metamorphosed to the adult stage after possession of 6 nauplius stages and 5 copepodid stages. The moulting rate was 66.7% from 1st nauplius stage to 2nd one and was 50.0% to 6th one. P. nana were needed 17 days for developing from hatching to adult.

Production of resting egg from the Korean rotifer, Brachiunus plicatilis (L and S-type) was investigated at different temperatures (L-type : 20, 24, $28^{\circ}C$, S-type : 28 32, $36^{\circ}C$) and salinities (10, 20,30 ppt). The rotifer was cultured in 25 ml test tube and fed on Nannochloris oculata. With regard to mixis rate, L-type rotifer showed higher rate at lower temperature, and the highest rate was observed at 20 ppt of salinity at each temperature of the experiment. However, for S-type rotifer, the optimum temperature and salinity were $28\~32^{\circ}C$ and 20 ppt, respectively. The highest number of resting egg was 173 eggs/ml in 16 days at $24^{\circ}C$, 10 ppt for L-type rotifer and 410 eggs/ml in 14 days at $28^{\circ}C$, 10 ppt for S-type rotifer. The maximum number of resting egg produced per 10,000 rotifers was 8,122 eggs at $20^{\circ}C$, 20 ppt for L-type rotifer and 8,700 eggs at $28^{\circ}C$, 20 ppt for S-type rotifer. The maximum number of resting egg produced $10^8$ cells of N. oculata was 50.7 eggs for L-type rotifer ($24^{\circ}C$, 20 ppt) and 79.6 eggs for S-type rotifer ($32^{\circ}C$, 10 ppt). The number of resting egg produced per day was $1\~11$ eggs/ml for L-type rotifers and $21\~35$ eggs/ml for S-type rotifer in 9 combination experiments. In this study, S-type rotifer is better than L-type rotifer in resting egg production, and the optimum temperature and salinity for resting egg production were $20^{\circ}C$, 20 ppt for L-type rotifer and $28^{\circ}C$, 20 ppt for S-type rotifer. This result shows the difference of Korean rotifer in the optimum condition for resting egg production from other rotifers reported earlier.

한국의 중부에 위치한 평창, 영월 지역은 석회암 지역이며 생물지리학적으로 매우 중요한 지역이다. 2010년 3월부터 10월까지의 조사로 평창, 영월 지역의 식물상을 밝혀 석회암 지역 식물 연구의 기초자료로 활용하고자 한다. 이 지역의 식물상은 134과 503속 1,010종 11아종 110변종 10품종 4잡종의 1,145분류군으로 확인되었다. 환경부 법적보호인 멸종위기야생식물은 7분류군이며, 한국고유종은 50분류군이었다. 식물구계학적특정식물은 238분류군으로 5등급 24분 류군, 4등급 30분류군, 3등급 60분류군, 2등급 45분류군, 1등급 79분류군으로 나타났다. 귀화식물은 82분류군이었으며, 본 조사지에서 다른 지역에 비해 특이하게 분포하는 식물은 53분류군이 확인되었다. 이 중 석회암 지역에서만 분포가 확인되는 식물은 35분류군이며, 격리되어 분포하는 북방계 식물은 15분류군, 해안성 식물은 3분류군이었다. Located in the middle part of the Korean peninsula, Pyeong-chang and Yeong-wol (Gangwon-do) areas are limestone regions that are important biogeographically showing the peculiar flora. In order to manage efficiently endangered and rare plant species, we have investigated flora of these above regions from March to October, 2010. The result of the investigation showed a total of vascular plants of 1,145 taxa; 134 families, 503 genera, and 1,010 species, 11 subspecies, 110 varieties, 10 forms and four hybrids. Among taxa investigated, endangered species designated by the law called ``Protection Law for Endangered wild fauna and flora`` were seven taxa, and 50 taxa were considered to be endemic to Korea. Based on the floristic degrees categorized by the specific distribution of plant species, 24 taxa revealed the floristic degree (FD) V, 30 for FD IV, and 60 for FD III, 45 for FD II and 79 taxa for FD I. The 82 taxa were identified to be naturalized. Of those species investigated in this survey, 53 taxa were identified as specific ones biogeographically as compared to flora of other terrestrial regions; 35 of calcicolous plants, 15 with distribution in the northern part of the Korean peninsula, three with coastal habitats.

Water-soluble crude polysaccharide (TM-1) prepared from the leaves of Teucrium viscidum var. miquelianum was fractionated into three polysaccharide fractions, TM-2, TM-3 and TM-4 by the addition of cetyltrimethylammonium bromide. The major polysaccharide fraction, TM-2, consisted of glucose, galactose, rhamnose, mannose, glucuronic acid and galacturonic acid, and all fractions contained galactose and glucose as the major neutral sugars. TM-4 showed the highest anti-complementary activity. When TM-4 was futher fractionated by anion exchange chromatography, TM4- Ⅱ a and TM4- Ⅱ b showed the most potent anti-complementary activity. TM4- Ⅱ a was composed mainly of galactose, arabinose and glucose in the molar ratios of 2.13 : 0.94 : 1.00 respectively, and contained a small amount of galacturonic acid and glucuronic acid.
