생태계 변화의 모니터링은 효율적 생태계 관리를 위한 기초 정보 수집을 위해 중요한 과정이다. 많은 생태 현상과 그 과정은 오랜 시간에 걸쳐 진행되므로 국립공원의 지속적인 보전 및 효율적 관리를 위해 생태계 모니터링은 장기적으로 이루어질 필요가 있다. 본 연구는 국내외 장기 모니터링 프로그램 사례 분석을 통해 성공적인 장기 모니터링을 위한 방법으로써, 최적화된 모니터링 설계, 표준화된 운용방안 마련, 인적 자원 및 DATA 관리 체계 수립, 안정적인 재정 마련 및 후속지원 등을 제시하였다. 이를 바탕으로, 현재 10년 넘게 수행되고 있는 ‘HS호 유류유출 사고 해역 장기 모니터링 프로그램’의 발전 방향으로 적응형 모니터링 방식이 적용된 표준화된 프로토콜의 정립, QA/QC와 지속적인 자료 관리, 조사 항목의 연계성 강화 등의 구체적 방안을 제안한다. Monitoring ecosystem changes is an important process for collecting basic information for ecosystem management. Since many ecological phenomena and their processes take place over a long period of time, it is necessary to conduct long-term monitoring of ecosystems for the continuous conservation and efficient management of national parks. This study suggested an optimized monitoring design, standardized operation plan, human resource and data management system, stable financial preparation and follow-up support as methods for successful long-term monitoring through case analysis of domestic and foreign long-term monitoring programs. Based on this, it proposes specific measures such as establishing a standardized protocol with adaptive monitoring methods, continuous data management with QA/QC, and strengthening the linkage of investigation items in the development direction of the “HS oil spill accident long-term monitoring program” that has been conducted for more than a decade.

The purpose of this study is to search on domestic and overseas designer's trends of Zen fashion in the latter half of 1990s. Zen fashion is know as one of the methods to prepare for new millenium fashion trend. In order to find out the information, books related fashion affair, magazine, theory, photographs, and collections of fashion works were used. The contents of this research are checking out the origin meaning of Zen and the background of the appearance in fashion trend. In conclusion, Zen fashion, as a millennium oriental look is considered as a kind of new minimal fashion, contemporary modernness in fusion style, and representing the purism.

이 연구는 포도의 생육기간에 사용되는 봉지의 특성이 포도의 생육과 당도에 어떤 영향을 미치는지 알아보고자 수행되었다. 포도의 생장에 영향을 미치는 많은 요소가 있지만 빛의 영향을 가장 많이 받는 것으로 알려져 있다. 그래서 미국과 유럽의 경우 다른 경제적인 이유도 있지만, 포도가 빛에 그대로 노출되도록 봉지를 씌우지 않는 무대재배를 한다. 국내의 경우는 식용 생과의 생산이 목적이기 때문에 포도의 생장기간에 병충해방지 및 과실의 착색효과 및 외관보호 등 여러 목적을 가지고 봉지를 씌워서 재배를 한다. 봉지의 구조에 따라서 포도의 생육과 당도에 영향을 미치게 되므로, 봉지를 만드는 원료인 섬유의 종류와 고해정도를 달리해서 봉지를 제작하여 포도를 생산했다. 실험실에서 제조한 종이로 재배한 포도의 당도가 기존에 사용되던 봉지로 재배된 포도보다 당도가 약 0.7 Brix 정도 높았다. 또한 침엽수 천연섬유와 침엽수 재생섬유, 침엽수와 활엽수 섬유를 혼합하여 만든 종이와 활엽수 섬유로 만든 종이가 빛의 투과성과 동도에 상반된 결과를 보였으며, 봉지가 빛을 많이 흡수할수록 당도가 높음을 알 수 있었다. 봉지내부의 온도변화를 측정한 결과 포도의 생육에 적정한 온도가 있음을 추정할 수 있었다.

Objectives: Selection of treatment methods for mandibular condylar fractures remains controversial. In this study, we investigated treatment methods for condylar fractures to determine the indications for open or closed reduction. Patients and Methods: Patients >12 years of age treated for mandibular condylar fractures with a follow-up period of ≥3 months were included in this study. The medical records of enrolled patients were reviewed for sex, age, fracture site, treatment method (open or closed reconstruction), postop-erative intermaxillary fixation period, operation time, and complications. Radiological analysis of fracture fragment displacement and changes in ramal height difference was performed using computed tomography and panoramic radiography. Results: A total of 198 patients was investigated, 48.0% (n=95) of whom underwent closed reduction and 52.0% (n=103) underwent open reduction. There was no significant correlation between reduction method and patient sex, age, or follow-up period. No statistically significant difference between the incidence of complications and treatment method was observed. None of the patients underwent open reduction of condylar head fracture. Binary logistic regression analysis showed that open reduction was significantly more frequent in patients with subcondylar fracture compared to in those with a fracture in the condylar head area. There was no statistically significant correlation between the groups and fracture fragment displacement. However, there was a significant difference between the treatment groups in amount of change in ramal height difference between the fractured and the non-fractured sides during treatment. Conclusion: No significant clinical differences were found between the open and closed reduction methods in patients with mandibular condylar fractures. According to fracture site, closed reduction was preferred for condyle head fractures. There was no significant relationship between fracture fragment displacement and treatment method.

This studies were carried out to investigate the quality characteristics of pork patties prepared with Crataegi Fructus ethanol extracts(CF; 1, 3, 5%). The water holding capacity of pork patties were decreased as increase of CF concentration. Cooking loss of pork patty prepared with 1% CF(PWC) did not show significant difference compared to control during storage periods. TBARS value of control was higher than that of PWC. Lipid oxidation of pork patties was inhibited by addition of CF during storage periods. The sensory quality such as taste, color, flavor and overall acceptability of pork patties prepared with CF was higher than those of control and increased as increase of CF concentration.

This study was conducted to examine the mRNA expression of apoptosis-related and imprinted genes and methylation pattern of the differentially methylated region (DMR) of H19 gene in day 35 of SCNT pig fetuses. The day 35 of natural mating (control) or cloned (clone) pig fetuses were recovered from uterus. Endometrium from dam and liver from fetus were obtained, respectively. mRNA expression was evaluated by real-time PCR and methylation pattern was analyzed by bisulfite sequencing method. The Bcl-2 mRNA expression in clone was significantly lower than that of control (p<0.05). The mRNA expression of H19 gene in both endometrium and liver was significantly higher in clone than that of control, respectively (p<0.05). The level of IGF-2 mRNA in liver of clone was significantly lower than that of control (p<0.05), whereas the mRNA expression of IGF2-R gene in liver of clone was significantly higher than that of control (p<0.05). The DMR of H19 was lower methylation pattern in clone than that of control. These results suggest that the aberrant mRNA expression of apoptosis-related and imprinted genes and the lower DMR methylation pattern of imprinted gene may be closely related to the inadequate fetal development of cloned fetus.

A numerical variation and abnormalities were studied on egg bags and embryos of Korean salamander, Hynobius leechii from agricultural habitat. The teratogenic and toxic effects of fungicide benomyl were also investigated with early embryos from non-agricultural habitat. We collected 144 egg bags from agricultural region, and 3418 of early embryos were contained. The lengths of egg bags were varied from 10 to 23㎝ and the most frequent length was 19㎝. The number of embryos was varied from7 to 43, and the most frequent range was 22 to 26. Spontaneous abnormalities were occurred in 406 embryos among 116 egg bags, and 24 kinds of external abnormalities were found. Individuals showing severe external defect were histologically studied and they showed optic dyspalsia, thyroid carcinoma, somatic muscular dysplasia, partial biaxial structure, decrease of red blood cells in the heart, cephalic degeneration and intestinal dysplasia. 385 embryos from non-agricultural region were exposed to 200nM∼1μM of benomyl at blastula or gastrula for 12 days. All embryo were dead in the concentration of 1μM(LD_100) and 75% of embryos were dead in 800 nM of benomyl. Specific effect due to benomyl was acrania or cephalic dysplasia and this result suggests that the benomyl inhibit strongly to the development of neural tissue. These abnormal developments may be caused by antimitotic action, inhibition of tubulin complex, destruction of microtubule, inhibitions of neurulation and closing of neural fold, and by the inhibition of the movement of neural crest cells.
