Objectives: This study aimed to survey the characteristics of air quality and meteorological conditions in a greenway park. Methods: We measured meteorological and health related factors, including noise, particulate matter ($PM_{10}$) and selected gaseous air pollutants at three locations in a greenway park and on a general roadside as comparison. The measurements were repeated four times from April to October 2014. Results: The average air temperature in the greenway park was $20.7^{\circ}C$ which was $1-2^{\circ}C$ lower than on the general roadside. The average $PM_{10}$ concentration in the greenway park was $85.0{\mu}g/m^3$, a level 2-3 times lower than that at the roadside. The noise level at the greenway site was 4.4 dB(A)- 23.0 dB(A) lower than at the roadside. The average CO, $CO_2$, $SO_2$ and NOx concentrations in the greenway park were lower than at the roadside. The average phytoncide and anions concentrations in the greenway park were higher than at the roadside. Conclusions: The urban forest of the greenway park may have some impact on air quality and meteorological conditions.

The study the use of breeding habits by different amphibian specis in the Woraksan National Park, nine amphibian breeding populations were monitored from March 25 to July 15, 2005. The breeding habits were categorized into the mountain stream, pond , or rice paddy type. On each survey, we counted the number of adults of amphibian species appeared at the breeding sites and alsp recorded the number of egg sacs or clumped egg clutches deosited by Hynobius leechii, Rana huanrenensis, or R. dybowskii. Total 199 adult amohibians of 9 species in 5 families were confired during the study period. Those were H. leechii, onychodactylus fischeri, Karsenia koreana in urodela and R. huanrenensis, R. dybowskii, R. nigromaculata, R. rugosa, Bombina orientalis, and Hyla japonica in anura. The K. koreana was the first report in the Woraksan National Park. In the Park, the most diminant species was R. dybowskii. In the mountain streans, H. leechii and R. huanrenensis were dominant. The peak breeding season based on the appearance of different amphibians in the areas varied and folled in order as H. leechii in March, R. huanrenensis, R. dybowskii in April, R. nigromaculata, B. orientalis, H. japonica in late May, and R. rugosa in early July. our results indicate that the breeding season of different amphibian species is widely spread from early spring to early summer and the preference for a breeding habitat is varilable based on the species.

Purpose: BOOP and NSIP also share similar clinical features such as subacute flu-like illness, the finding of bronchoalveolar lavage, the result of pulmonary function test and more favourable outcome than usual interstitial pneumonia(UIP). The author try to compare the HRCT findings of NSIP with BOOP by pattern and distribution of diseases. Materials and Methods: HRCT findings of histopathologically proven NSIP(Group Ⅰ; 6, Group Ⅱ; 7, Group Ⅲ; 2) in 15 patients(5 male, 10 female, age range, 39-69 years; mean age, 53 years), BOOP in 15 patients(6 male, 9 female, age range, 26-76 years; mean age, 52 years) were reviewed retrospectively. Results: The common pattern of the two diseases was admixed consolidation, ground glass attenuation & reticular densities with/without architectural distortion(NSIP; 53.3%, BOOP; 46.7%). The main component of the pattern wan predominantly consolidation(NSIP; 46.7%, BOOP; 73.3%) and ground glass attenuation(NSIP; 40.0%, BOOP;20.0%). Architectural distotion was more provinent finding with NSIP(mild ; 3, moderate ; 4, severe; 2) compared with BOOP(mild; 7, moderate; 2, severe; 0). The predominant overall distribution was lower lung, peribronchovascular & peripheral lung field in both of the two entities(NSIP;73.3%, BOOP; 73.3%). Peribronchovascular involvement was more common with NSIP(100%) than BOOP(80%), whereas peripheral involvement was more common with BOOP(93.3%) than NSIP(80%). Conclusion: The HRCT findings of NSIP and BOOP were similar in pattern and distribution. But NIP manifested more frequently ground-glass attenuation, whereas BOOP showed more frequently consolidation. Architectural distortion was more severe with NSIP than BOOP. NSIP invoved more frequently peribronchovascular space and BOOP were more common in peripheral lung field.

오늘날 현저한 CO2 레이저의 응용 추세에 발맞추어 보다 다양한 형태의 출력 제어 기술이 대두되고 있다. 본연구에서는multi-Pulse Superposing-Discharge 기술을 이용하여 다양한형태의 CO2 레이저의 펄스를 성형 하였다. 펄스 성형을 위한 방법으로 PIC one-chip microprocessor를 이용하여 삼중 PFN 모률의 SCR을 각각 고유의 지연시간을 가지도록 제어하였다. 실험에 사용된 삼중 PFN 모률의 전원 회로는 각각 캐패시터 인덕터,SCR,고압 펄스 트랜스 그리고 고압 트랜스 2차측에 브릿지 정류기로 구성 하였다. 고압 펼스 트랜스의 1차측을 제어하므로서 PFN 모률의 동작을 저 전압에서 수행 할 수 있다. 트랜스의 2차측에 연결된 전파 정류기는 펄스 에너지를 부하에 지속적으로 전달한다. 본 연구에서는 삼중 PFN 모률의 각각의 SCR을 다른 시간 가격을 두고 트리거 하므로서 다양한 Long pulse shaping을 실현하였다. 또한 약 250-1000μs 의 주기를 가지는 다양한 펄스형 레이저 빔을 얻었다.

본 연구는 PIT tag (passive integrated transponder)과 무선추적법(radio telemetry)을 오대산국립공원과 월악산국립공원에 서식하고 있는 파충류에 적용한 후, 이를 평가하여 효과적으로 국립공원 내 파충류 자원관리 방안을 모색하기 위하여 수행되었다. PIT tag은 현재까지 알려진 파충류 개체표시법 중에서 가장 효과적인 방법으로 2006년 3월부터 2008년 10월까지 오대산국립공원과 월악산국립공원의 조사지역에 출현한 모든 137마리의 뱀류를 대상으로 적용하였다. 무선추적 연구는 월악산국립공원에서 서식하고 있는 황구렁이(Elaphe schrenckii anomala) 2마리를 대상으로 2007년 9월부터 2008년 11월까지 실시하였다. 연구결과, 두 곳의 국립공원 지역에서 연구기간 동안 17마리가 재 포획되어 평균 12.40%의 재포획률을 보였으며, 재 포획된 개체들의 자료를 통하여 누룩뱀(Elaphe dione)과 쇠살모사(Gloydius ussuriensis) 성체의 SVL 증가를 성공적으로 확인하였다. 무선추적을 통하여 확인된 황구렁이 수컷의 행동권 면적은 MCP=389,600 m2, Kernel 95%=471,800 m2, 암컷은 MCP=162,500 m2, Kernel 95%=208,700 m2인 것으로 확인되었다. 국립공원 내에서 보호와 관리가 필요한 종 혹은 멸종위기대상 종인 파충류를 대상으로 PIT tag과 무선추적을 적용한다면 공원 내 파충류의 효율적인 관리 및 보존방안을 마련하는 데 중요한 기초자료를 제공할 수 있을 것으로 생각된다. To suggest effective ways of the management of reptiles in Korea national parks, we applied PIT (passive integrated transponder) tag and radio telemetry research methods in the monitoring of reptiles in Odaesan and Woraksan national parks. We implanted PIT tags into 137 snakes (six species) captured in both the national parks between March 2006 and October 2008 and also radio-tracked two Korean rat snakes (Elaphe schrenckii anomala) from September 2007 to November 2008 in the Woraksan national park. Of total 137 snakes which we had inserted the PIT tag, 17 snakes (12.40%) were recaptured. Based on the PIT tag data of the recapture, we successfully obtained the annual growth rate of Korean cat snakes (Elaphe dione) and Red-tongue pit-viper (Gloydius ussuriensis). Home range of the Korean rat snakes based on the data of radio-tracking was estimated as 389,600 m2 (MCP: Minimum convex polygon) and 471,800 m2 (Kernel 95%) for males and 162,500m2 and 208,700m2 for females. These results suggest that if we apply PIT tag and radio telemetry research methods to manage reptiles in Korea national parks, it could greatly increase our understanding about their basic ecology and as the result, it could allow us to develop better management and conservation ways of reptiles in Korea national parks.

Transglutaminase(TGase) catalyzes the Ca^2+ dependent acyl transfer reaction to from γ-glutamyl lysine cross-links between substrate proteins. we have examined the expression of TGase 1 and TGase 2 enzyme activity and protein expression in differentiation induced salivary gland cells(HSG), and human salivary adenocarcinoma cell lines(SGT)in reation to anchorage independent growth. The TGase1 and TGase 2 activity in SGT was higher than in HSG, and there is no significant difference between TGase 2 and TGase1 cells. HSG cells showed no increase in TGase 1 and TGase 2 upon reaching post confluence and in 1.8mM Ca^2+. Expression of the TGase 1 and TGase 2 was induced by high cell density or by high calcium in SGT. No induction of TGase 1 & 2 protein was observed in postconfiuent HSG cells, but there was notable increases in TGase 1 & 2 protein in post confiuent SGT cells. This pattern of TGase 1 & 2 protein expression correlates with the pattern of particulate activity. SGT cells showed more colony size and colony forming activity in soft agar rather than HSG cells. The ability of SGT cells, containing high levels of TGase 2 and TGase1,to form colonies in soft agar suggests a role for this enzyme in anchorage independence.

한국현대시와 부산의 정신성 : 부산항과 자갈치를 중심으로

박대현 부산대학교 한국민족문화연구소 2006 한국민족문화 Vol.28 No.-

The purpose of this study is research on the mentality of Busan in the Korean modern poetry. Busan Port was both a inflow route of modern civilization and a bridgehead of colonial plunder. And it was crowded with korean abroad returning to Korea and refugees in the periods of liberation and the Korean War. Jagalchi had started no be brought into relief through periods of opening a porn and Japan's colonial rule of Korea. Space symbolizing Busan had been led by Busan Port until the period of the Korea War, bun from then on, has been led by Jagalchi. A weight shift of mentality has been accomplished by symbolism of Busan transferring from Busan Port to Jagalchi. On the one hand Busan Port had formed a economical foundation of modern project in a flow of modernity, and on the other Jagalchi has acquired a mass's symbolism as mass's life space. Therefore Jagalchi has become symbolic space of mass's literature by acquiring a symbolism as poor mass's living grounds in the period of the Korean War. Bat Jagalchi get faced with lost of the nature of masses, because in could be eliminated from Jagalchi owing to the project of modernizing Jagalchi. In other words, the mentality of Busan is faced with danger in lost of mass's symbolic space. Therefore, it must be a important following task how to preserve and incarnate the nature of masses in the mentality of Busan.
