  • 본 연구는 전국의 64개 관측지점을 대상으로 $1972{\sim}1995$년의 자료를 해마다 $K{\ddot{o}}ppen$ 구분방법에 적용시켜 기후 특성을 고찰하였다. 우리나라의 기후는 Cfa Cwa Cwb Dfa Dwa Dwb의 연후형 으로 구성되고, Cwa Dwa형의 출현빈도가 전체의 95%를 점한다. Cwa형의 출현은 대부분의 남부 지방 동사면 제주도에서 우세하고, Dwa형은 영서 경기 복동부에서, Cfa형은 울릉도에서 탁월하게 나타난다. 이런 우세지역은 안정된 기후지역을 형성하지만 다양한 기후형이 출현하는 남부 진방의 북부와 중부 지방의 남부는 C와 D형이 상접하는 경계이므로 불안정 기후지역을 이룬다. 또한 Cwa형이 가장 우세했던 1990년대 전반기에는 C D형의 경계선이 중부 내륙 지방에 위치하였고, Dwa형이 가장 탁월했던 1980년대 전반기에는 C D형의 경계선이 남부 지방의 중위에 위치하기도 하여 해에 따라서 연후지역의 범위가 변한다. 주요 연후형의 경년변화에서 Cwa형은 증가경향을 보이지만 Dwa형은 감소추세를 나타낸다. Cwa 연후지역의 확장추세는 1970년대 전반기와 1980년대 후반기 이후 최근까지 남부 지방을 중심으로 계속되고, 1980년대 전반기에 중부지방에서 우세했던 Dwa 연후지역은 최근까지 축소되고 있다.

  • 최근 충남 보령 일대에 분포하는 후기 트라이아스기의 아미산층에서 밑들이목에 속하는 날개 화석이 처음 발견되었다. 날개 화석은 그 맥의 특징에 의해 Mesopsychidae과의 Mesopsyche dobrokhotovae로 분류되었다. 이 속에 속하는 화석 곤충은 후기 트라이아스기에 세계적인 분포를 보이며 상당히 번성한 그룹이었다고 추정된다. 현생의 밑들이는 나뭇잎, 식물 줄기 등에 매달려 있거나 습한 환경에서 작은 곤충을 섭식하며 생활한다. 따라서 밑들이 화석의 존재는 후기 트라이아스기 동안 남포 층군이 퇴적될 당시의 서식 환경이 이미 현생의 환경과 상당히 비슷했다는 것을 지시한다. Mesopsyche dobrokhotovae는 우리나라에서 발견된 곤충화석 중 가장 오래된 화석의 하나이며 밑들이 화석으로는 최초의 기록이다.

  • Objectives : This study is to report the percentage of localized itching which occurred, when we injected to patients with Sweet Bee Venom(Sweet BV). Methods : We investigated 374 patients who had injected with Sweet BV in our clinic from February 15. 2009 to April 30, 2010. We checked the number and percentage of patients who occured localized itching on injection area. Then we analyzed those according to times in treatment, the body parts of injection and treatment dosage. Results and Conclusion : Localized itching was lower by 1.60% in the first treatment with Sweet BV. However localized itching was 12.83% in the whole course of treatment, which showed a similar incidence of 13% in Bee Venom. Therefore it can be interpreted that Sweet BV may help suppress the immune responses such as itching in the initial treatment, but the occurrence of local immune responses of Sweet BV may be similar to that of Bee Venom in continued treatment. We suppose that we should be careful of the occurrence of local immune responses as Bee Venom at least until the fourth treatment in clinical application with Sweet BV, although localized itching did not occur in the first treatment. Also we should be careful of treatment with Sweet BV in body parts, such as wrist, hand, chest and abdominal, because the percentage of localized itching was relatively high in those parts.

  • The first occurrence of a giant squid, Architeuthis sp. (one specimen), and the oarfish, Regalecus russellii (two specimens) in the East Sea were reported based on specimens collected in January and February 2010. The giant squid (Architeuthis sp.) stranded at Pohang in Jan. 2010 was female, 175 cm in mantle length (ML), 506 cm in tentacle length (TL), and 33.9% FL/ML, it contained common squid beaks. Both stranded oarfish (Regalecus russellii) at Uljin (Jan. 2010) and Yeongdeok (Feb. 2010) were male, with total weigths (TW) of 18,506 and 21,703 g and total lengths (TL) of 3,850 and 3,670 mm, respectively. The stomach of the first was empty, while that of the second was filled with euphausiids. In the East Sea, giant squid have been stranded 14 times in five areas, while 17 oarfish have been stranded in nine areas. Since 1990, the two species have been found most often at Pohang.

  • Purpose: This study was designed to analyze the behavioral change of knowledge structures and the trends of research topics in the quality management field. Methods: The network structure and knowledge structure of the words were visualized in map form using co-word analysis, cluster analysis and strategic diagram. Results: Summarizing the research results obtained in this study are as follows. First, the word network derived from co-occurrence matrix had 106 nodes and 5,314 links and its density was analyzed to 0.95. Average betweenness centrality of word network was 2.37. In addition, average closeness centrality and average eigenvector centrality of word network were 0.01. Second, by applying optimal criteria of cluster decision and K-means algorithm to word co-occurrence matrix, 106 words were grouped into seven clusters such as standard & efficiency, product design, reliability, control chart, quality model, 6 sigma, and service quality. Conclusion: According to the results of strategic diagram analysis over time, the traditional research topics of quality management field related to reliability, 6 sigma, control chart topics in the third quadrant were revealed to be declined for their study importance. Research topics related to product design and customer satisfaction were found to be an important research topic over analysis periods. Research topic related to management innovation was emerging state and the scope of research topics related to process model was extended to research topics with system performance. Research topic related to service quality located in the first quadrant was analyzed as the key research topic.

  • The so-called 'Bustle'which was a support put on waist to heave the side the buttocks means the grandiloquent style to express to ideal body. Bustle style. one of the outstanding and remarkable fashion trends in the late 20th century, has significant meaning in fashion history. This is because not only the style has the longest history, but also it has been periodically repeated every end of a century from the 17th to the 20th century. To analyse to cause the Bustle style was shown, I studied first the sign of forthcoming activity of the Bustle style, the change of the Bustle style shown In the times at the end of century and feature of the Bustle style. Based on the previous reasons of appearance of the Bustle style In the history. there are two similarities. First. reaction led to an occurrence of the reactionary tendency, the Bustle style as they were eager for the past because of a feeling of uneasiness about a coming century. Second, the principle of retrogression led to an occurrence of the Bustle style craving for new style. This Bustle style welch was reaction from being tired of the former fashion appeared to expression a desire for new style. In short, Bustle style was an intermediation between different histories and the basis for continuous development of new eras. rather than lust a part of classicism.

  • We investigated the effect of reproductive herd health program (RHHP) on the reproductive performance in high yielding dairy herds. Data collected from 205 lactations at Boeun County, Chungbuk from April 2001 to Dec. 2003 included postpartum reproductive and metabolic diseases, body condition score (BCS), reproductive performance and milking records. First we compared the reproductive performance of cows without RHHP (pre-RHHP group) and cows with RHHP (RHHP group). Intervals from calving to first service (99.6 vs. 81.8 days) and to conception (160.3 vs. 131.8 days) were shorter in the RHHP group than in the pre-RHHP group. Secondly, we determined the effect of milk yield (305 days) on the occurrence of postpartum diseases, BCS changes, and reproductive performance in cows under RHHP. The occurrence of metritis and metabolic diseases were greater in the over-10,000 kg group than in the under-10,000 kg group. The over-10,000 kg group lost more body condition than the under-10,000 kg group from calving to month 3 postpartum. Nevertheless, reproductive performance did not differ between the two groups. These results indicate that reproductive performance can be improved by the application of RHHP in high yielding dairy herds and that reproductive performance in the cows under RHHP are not affected by high milk yielding.

  • The purpose of this study was to analyze the effect of fire fighters' duty type on occurrence and severity of low back pain. Data were collected with questionnaire to 450 fire fighters working at 119 safety center and rescue unit of 30 fire stations in Gyeonggi-do. Finally the study was analyzed for 360 persons among them. The risk of experiencing of lower back pain occurred in the order of Rescue[odds ratio(OR) 3.36, 95% confidence interval(95% CI) 1.18-9.52], Vehicle operation(OR 2.63, 95% CI 1.26-5.50), First aid(OR 2.18, 95% CI 1.03-4.59), and Putting out a fire. The risk on severity of lower back pain occurred in the order of Vehicle operation(OR 4.00, 95% CI 1.57-9.80), First aid(OR 1.88, 95% CI 1.00-4.81), Putting out a fire, and Rescue. These result suggest that duty type of fire fighters may be a prognostic factor for occurrence and severity of low back pain. The potential implications of these findings are discussed about different approach for primary and secondary prevention by duty type of fire fighters.
