The sugar beet cyst nematode (SBCN), Heterodera schachtii first detected in Taebaek, Gangwon-do in 2011, is one of the major plant parasitic nematodes that cause economic damage to the Chinese cabbage in highland regions. In addition, the distribution of clover cyst nematode (CCN), H. trifolii was confirmed in the highland Chinese cabbage cultivated regions in 2017. In order to investigate the spread of cyst nematodes, this study has been conducted since 2013 in the highland Chinese cabbage cultivation area. In addition, in 2017, the Real-Time PCR technique with the species-specific primer was used to investigate those two cyst nematodes and the soybean cyst nematode (SCN), H. glycines which is known for its distribution in Korea, focusing on the main production regions of highland Chinese cabbage cultivation. The number of infected fields in the Chinese cabbage plantation in highland increased every year to confirm distribution in Taebaek, Samcheok, Jeongseon and Gangneung in 2017, and the cumulative number of infection fields reached 245 by 2017. Of the 41 possible cyst nematode samples for PCR analysis, 61% were CCN, only 9.8% of the SBCN and 29.3% of the SCN were identified. Therefore, some of the previously known SBCN or CCN discoveries are likely to have been infected with SCN. It is believed that the CCN needs to be controlled in the future as CCN have been found to be dominant species in the highland Chinese cabbage plantation regions.

The fundamental study of hydrologic redesign of Donghwa area located in a sccond tributary of Seomjin river was performed. The amounts of hydrologic design were estimated using the available cumulated hydrology data provided by Korea Agricultural and Rural Infrastructure Corporation (KARICO). The management status of The water resources in Donghwa area was also widely surveyed. The probability rainfalls, probable maximum precipitation (PMP) and probability floods were estimated and subsequently their changes analyzed. The amount of 200 year frequency rainfall with l day duration was 351.1 mm, 2.5 % increased from the original design value, and The PMP was 780.2 mm. The concentration time was reestimated as 2.5 hours from existing 2.4 hours. Soil Conservation Service(SCS) method was used to estimate effective rainfall- The runoff curve number was changed from 90 to 78, therefore the maximum potential retention was 71.6 mm, 154 % increased from the original value. The Hood estimates using SCS unit hydrograph showed 8 % increase from original value 623 $m^3$/s to 674 $m^3$/s and The probable maximum Hood was 1,637 $m^3$/s. Although the Row rate at the dam site was increased, the Hood risk at the downstream river was decreased by the Hood control of the Donghwa dam.

Background:Pain in the form of acute neuritis and postherpetic neuralgia is by far the most frequent and most debilitating complication of herpes zoster. The pain of acute herpes zoster may be severe, but it is usually transitory. Some patients, with the elderly at particular risk, go on to develop postherpetic neuralgia. Postherpetic neuralgia is often severe and, unfortunately, refractory to most forms of treatment. Objective:The purpose of this study was to compare the severity of acute pain and incidence of postherpetic neuralgia by age group, dermatomal distribution and the presence and absence of associated diseases. Methods:We observed the severity of initial pain, changes in severity of pain during treatment, and the incidence of postherpetic neuralgia in 105 patients with herpes zoster with the same therapeutic measures (systemic steroid, acyclovir, analgesics, and tricyclic antidepressant). And we compared them by age group (the young & middle age vs the old age group), dermatomal distribution(trigeminal, cervical, thoracic, and lumbosacral), and the the presence and absence of associated diseases respectively. And we also analyzed the relationship between the incidence of postherpetic neuralgia and the severity of initial pain. Results:1. Sixty-six patients (63%) of the total number of subjects complained of initial `severe pain', and the incidence of initial `severe pain' was significantly higher in the old age group (78%) compared with the young & middle age group (48%). But, there was no significant difference by dermatomal distribution and the presence and absence of associated diseases. 2. The duration of pain was 2-4 weeks in 27 patients (26%), 1-2weeks in 26 (25%), more than 8 weeks(postherpetic neuralgia) in 24 (23%). 3. The mean comparative value of the severity of pain was 38% of initial pain after 3 days of treatment, 22% 1 week, 15% 2 weeks, 8% 4 weeks, and 5% 8 weeks, respectively. But, there was no significant difference in changes of severity of pain by age group, dermatomal distribution, and the presence and absence of associated diseases. 4. The incidence of postherpetic neuralgia was significantly higher in the old age group (35%) compared with the young & middle age group (11%). But there was no significant difference by dermatomal distribution and presence and absence of associated disease. And the incidence of postherpetic neuralgia was also significantly higher in the initial 'severe' pain group (33.3%) than in the initial 'mild' pain group (14.3%) and the `moderate' pain group (3.1%). Conclusions:Older patients with herpes zoster showed severer initial pain and a higher incidence of postherpetic neuralgia. But there was no significant difference in the severity of initial pain and incidence of postherpetic neuralgia by dermatomal distribution and the presence and absence of associated diseases. And patients with initial severe pain showed a higher incidence of postherpetic neuralgia than those with mild and moderate pain, respectively. (Korean J Dermatol 2000;38(3):314~321)

Bypass surgery, as therapy for morbid obesity, was introduced in 1952. Multiple complications such as arthritis and dermatitis as well as liver dysfunction, renal injury, diarrhea, malnutrition and electrolyte imbalance were reported after bypass surgery. Recently, we have experienced a case of bypass arthritis-dermatitis syndrome in a patient after pyloric exclusion and bypass gastrojejunostomy due to traumatic duodenal perforation. He complained arthralgia of left knee, both wrist and both ankle and developed erythematous maculopapular rash over lower extremities. He was successfully treated with NSAIDs and clindamycin.(Korean J Med 59:583-586, 2000)

An antibacterial component was isolated from the roots of evening primrose(Oenothera odorata Jacquin). The component was purified by repeated preparative TLC of the chloroform-extract with solvent system of toluene(7):ethyl acetate(4):formic acid(O.8). NMR spectrum indicated that it is a steroid compound containing radical(-C=C-C=0) and aromatic structures. Its antibacterial activity against strains of the genus Streptococcus was relatively high, the MIC value was 50 acccording to the Hoechst Manual-345, as compared with the other genera such as Staphylococcus and Escherichia.

기존에 운행되는 중량전철은 천문학적인 예산이 투입되고, 수송량이 많을 경우 유용하나 수송량이 상대적으로 적은 지방 소도시는 중량전철을 적용하기에 비용의 문제가 있다. 또한 현재 전력소비량이 날로 증가하여 국가적인 차원에서 전력수급이 문제가 되고 있으며 에너지의 효율적인 사용이 점점 중요시 되고 있는 시점이다. 무가선 저상 트램은 건설비용의 절감, 에너지의 재사용, 편안한 승하차 등의 장점으로 기존 중량 전철의 문제점을 극복할 새로운 교통수단으로 대두되고 있다. 본 논문에서는 리튬 - 폴리머를 활용한 무가선 저상 트램에 적용된 추진제어시스템을 소개하고자 한다. Exsiting mass rapid transit needs too much astronomical budget and it is useful in case transported volume is large, but It is a waste of money to apply to local towns that has small transport of volume. Also at the state level, increasing power consumption and power supply are the problem, so efficient use of energy is increasingly important in the present. The advantages of low-floor trams that has advantage of reduce construction costs, the reuse of energy, comfortable rides, etc has emerged as a new transportation to overcome the problems of the existing train. In this paper, we introduce a propulsion system using lithium-polymer is applied to a non-catenary low-floor tram.

본 논문에서는 출력 인덕터와 변압기를 결합시킨 하프브리지 컨버터의 자기회로 해석에 대하여 논하였다. 전력 변환 시스템에서 에너지의 저장, 변환, 전기적 절연 및 필터 등을 위한 자성체의 적절한 설계는 매우 중요하다. 본 연구에서는 출력 인덕터와 변압기를 하나로 결합시키므로 자성체의 수를 저감시킨 하프브리지 컨버터를 제안하였고, 릴럭턴스 모델을 바탕으로 자기회로의 특성을 비교 및 분석하였다. 본 연구에서는 제안된 릴럭턴스 모델의 타당성을 검증하기 위하여 MOSFET를 사용하여 100[W]급 시스템을 제작했으며 400[kHz]에서 실험하였다. This paper presents the analysis of magnetic circuit for the Half-Bridge converter using Transformer integrated with Output Inductor. In converter system, magnetic components are important devices used for energy storage, energy transfer, galvanic isolation and filtering. The proposed Half-Bridge converter is to reduce the number of magnetic components using transformer integrated with output inductor. This paper proposes reluctance model base on the magnetic analysis for the Half-Bridge converter. A prototype featuring 400[V] input 10[V] output, 400[kHz] switching frequency, and 100[W] output power using MOSFET.
