유철인,고남욱,고창훈 제주대학교 1986 논문집 Vol.16 No.1

Recent introduction of citrus cultivation causes the growth of Cheju regional economy with the inflow of external captial under the influnce of external market. These processes result in the Cheju regional economy dependent upon the national economy. Since the advent of large-scale tourism often necessitates the transfer of local control to a central government, Cheju society as a touristic place is more dependent on national society with the national development projects on Cheju island. These tourism and citrus cultivation cause rapid urbanization, more access to education, more exposure to mass communication, and the increase in the mobility of both of Cheju islander and mainlander, As a result, Cheju culture becomes more assimilated into mainland or national culture. We call these recent phenomana the social articulation between Cheju island and mainland as a larger society. The term articulation is the congruence or working together of differrent strata or different levels such as the articulation of modes of producction. Paticularly, as used in this paper, it describes the process by which the local island society becomas in corporated more fully into the larger society. This paper examines (1) the phenomena social articulation between Cheju island and mainland in terms of regional economy and policies, (2) the response of community to this articulation, and (3) its impacts on the development of Cheju island and the prospects of desirable relationship between local island society and the center. First of all, Cheju industry structure consists of 34.9% in the primary, .3% in the secondary, and 60.8% in the itertiary industry,in terms of vaules added as of 1981, while in 1971 the primary industry dominant. Employments by industry In Cheju region as of 1981 consist of 71.7% in the primary, 3.2% in the secondary, and 25.1% in the tertiary industry. Cheju regional economy is articulated with national economy because of citrus cultivation and products of fishery under influendces of domestic and foreign markets as well as a tourism industry as a leading industry for regional development. People in Cheju island feel the state of alination with these overwhelming changes, which is followed by outsider's speculation on land, the leakage of benefits resulted from outside capital investment, and the evnvironmental pollution. These phenomena may be discovered in the transformation from the closed socioeconomic system to the open socioeconomic system. Seocond, the articulating process of structual dependency of political, economic, and social fields is reavealed concretely in the process of formulation, making, and implementation of polities. The philosopical foundation of policy is not the philosophy of Small-is-beautiful, but the philosophy of Big-is-good. And the goal of policy is sought out without conscideration of the basic problems such as openess and closedness, national-oriented and international-oriented development and conservation, and active participation and passive alination of islanders. We learn that the formulation, content, and implemantation by national elites affected by not the volition of residents in Cheju-Do, but the vested interest of large firms and international capital investment. Its effects are expressed in terms of the alination, the powerlessness, and the suffering of Cheju islanders. Third, under the vast process of acculturation, these overwhelming waves of change do stimulate the Cheju society as a so-called periphery in acquiring a consciousness of the degree of exploitation it is subjected to. As an adaptive action, Cheju cultural identity is maintained and/or invented with the emphasis on its own traditional spirits, which may be considered as the revitalization movements in Cheju culture. Ambivalance toward mainland as an outer world is expressed in everyday life in Cheju society. Ambivalance toward an outer world is thought to be discovered in any society articulated with and dependent upon the lager society. Cheju islanders also miss tat Cheju culture becomes more assimilated into mainland or national culture. We consider the social articulation of Cheju island and mainland amid historical context of the contacts with mainland as sociocultural forces which operate to create Cheju cultural identity. The aura of Cheju cultural identity and traditionalism is one of the devices which insures the continuance of boundaries between Cheju islander and non-islander (mainlander) within a tourism and the migration of mainlanders, Cheju islanders' perception of what mainlanders think about Cheju islanders operates to create the meaning and content of their cultural identity is maintained may consist of the contacts with mainlandsers and the formation of an image on them. We concluded that the articulation must be transformed from total dependency into the equity through the structual autonomy, changes in policies, and cultural autonomy This means the balance of everyday ilife in an island and a mainland, and further, in the center and peripheries. Alternatives for this desirable articulation are as follows. First of all, the decentralized and autonomous political-administrative structure, the active and intensive regional economy, and social cultural development focused on community must become to be interrelated in order to be an intergrated development from within. Secondly, the development policies must be fundamentally changed in terms of basic philosophy, content, and implempentation. Lastly, the cultural diversity is to be fully appreciated, based on the understanding of local cultures or subcultures.

Objectives : The present study was designed to assess the reliability and validity of Korean version ofFamily Questionnaire (FQ-K), a briefquestionnaire measuring expressed emotion (EE). Methods : A sample of 84 first-order relatives ofschizophrenics completed the FQ-K and the data were analyzed for intemal consistency and factor structure. Additionally non-random subset of participants (n=34) refilled FQ-K after two weeks for test-retest reliability and naturalistic follow-up data of 36 were obtained for any re-hospitalization events to assess predictive validity. Results : Intemal consistency of FQ-K was good (Cronbach's alpha=.819) and pimcipal component factor analysis revealedthe two-factor structure (criticism and emotional overinvolvement) identical to previously reported for the FQ. The FQ-K also showed reasonable test-retest reliability and excellent predictive validity was indicated in that outcome of re-hospitalization was superior for low expressed emotion patients at six-month naturalistic follow-up. Conclusion : The Korean version of FQ Proved to be a reliable and valid instrument measuring expressed emotion in relatives of Korean patients with schizophrenia.

Purpose: Resection of the bowel or solid organs may be required for pelvic tumor surgery. The present study was performed to assess combined surgical procedures and determine the role of the general surgeon in gynecologic oncology surgery Methods: We performed a retrospective study of 135 patients with gynecologic malignancy who underwent a combined operation with a general surgeon between January 2000 and December 2005 at Asan Medical Center. The purpose of the combined operation was categorized into 3 groups: a tumor debulking operation, a resolution of intraoperative complications by a gynecologic surgeon, or an intraoperative diagnostic change. Results: The incidence of combined operations for debulking, resolution of intraoperative complications, and intraoperative diagnostic changes were 103 cases (76.3%), 22 cases (16.3%), and 10 cases (7.4%), respectively. Ovarian cancer was the most common gynecologic malignancy (74.1%) and the rate of a combined operation with a general surgeon in ovarian cancer was 18.5% during the time period. Colorectal resection was the most common procedure by a colorectal surgeon (61.5%). Twenty four patients (17.8%) experienced postoperative complications, including ileus, wound infection, pancreas leakage, and stomal necrosis, with no significant differences according to the purpose of combined operation, pathologic diagnosis, or bowel preparation. The rate of a preoperative consultation to a general surgeon by gynecologic surgeons in cases with colorectal or solid organ invasion preoperatively was 53.2%. Conclusion: A general surgeon is an important consultant in a debulking operation of gynecologic malignancies, especially ovarian cancer, or treatment of complications. Thorough preoperative evaluation, bowel preparation, and preoperative consultation to a general surgeon is important in gynecologic oncology surgery.

온실가스 배출 증가에 의한 기후변화는 화분매개곤충과 식물과의 생태적 상호작용인 수분생태계와 농업생태계를 포함한 자연생태계를 변화시킬 수 있다. 특히 수분생태계에서 중요한 야생벌(wild bee)은 기후변화에 의해 감소되고 있어서 결국 농업경제, 현화식물의 생태활동, 나아가 전체 생물종 다양성에 악 영향을 끼치고 있음이 보고되고 있다. 따라서 지구온난화에 의해 한반도(남한)에서도 매년 기온이 상승하고 있고, 그에 따른 기후변화 발생으로 한반도 내 야생벌의 생태활동에 영향을 주고 있음을 예상할 수 있다. 본 연구에서는 한반도(남한)에서 출현하는 야생벌(꿀벌상과, 말벌상과, 청벌상과)의 분포와 기후요인과의 관계를 검정하기 위하여, 2017년(37 조사지점)에서 2018년 (14 조사지점) 까지 총 51개 조사지점을 대상으로 말레이즈 트랩을 이용하여 야생벌류의 출현현황을 파악하였다. 형태 및 문헌을 통해 동정한 야생벌류와 산림기후대에 따른 분포는 평균기온, 적산온도와 상관성이 있음을 확인하였다. 이러한 결과를 바탕으로 공통사회 경제경로(Shared Socioeconomic Pathways, SSP) 시나리오의 2-4.5와 5-8.5버전으로 BIOMOD 종분포 모형에 따라 남한 전역에서 출현한 야생벌과 기후대별로 특이적으로 출현한 종의 서식지 분포 변화를 예측하여 현재의 종 서식지 분포에서, 2050년과 2100년에 북쪽으로 서식지가 이동함을 확인하였다. 이를 통해 향후 지구온난화가 지속될 경우 국내 야생벌의 분포 변화가 일어 날 수 있고, 그로 인한 한반도의 생태계 변화가 야기될 수 있음을 예측할 수 있었다. 본 연구결과는 기후변화에 따른 수분생태계 및 그와 관련된 영향에 대한 연구와 야생벌 관리를 위한 정책수립을 위해 참조할 수 있는 연구자료가 될 수 있을 것으로 기대하고 있다. Climate change caused by increased greenhouse gas emissions can alter the natural ecosystem, including the pollination ecosystem and agricultural ecology, which are ecological interactions between potted insects and plants. Many studies have reported that populations of wild bees, including bees and wasps (BW), which are the key pollinators, have gradually declined due to climate change, leading to adverse impacts on overall biodiversity, ultimately with agribusinesses and the life cycle of flowering plants. Therefore, we could infer that the rising temperature in Korean Peninsula (South Korea) due to global warming has led to climate change and influenced the wild bee’s ecosystem. In this study, we surveyed the distributional pattern of BW (Superfamily: Apoidea, Vespoidea, and Chrysidoidea) at 51 sites from 2017 (37 sites) to 2018 (14 sites) to examine the effects of climatic factors on the nationwide distribution of BW in South Korea. Previous literature has confirmed that their distribution according to forest climate zones is significantly correlated with mean and accumulative temperatures. Based on the result, we predicted the effects of future climate changes on the BW distribution that appeared throughout South Korea and the species that appeared in specific climate zones using Shared Socioeconomic Pathways (SSPs). The distributions of wild BW predicted by the SSP scenarios 2-4.5 and 5-8.5 according to the BIOMOD species distribution model revealed that common and endemic species will shift northward from the current habitat distribution by 2050 and 2100, respectively. Our study implies that climate change and its detrimental effect on the ecosystem is ongoing as the BW distribution in South Korea can change, causing the change in the ecosystem in the Korean Peninsula. Therefore, immediate efforts to mitigate greenhouse gas emissions are warranted. We hope the findings of this study can inspire further research on the effects of climate change on pollination services and serve as the reference for making agricultural policy and BW conservation strategy

Chang-Hun You,김병권,Jung-Man Kim,Seungdo Yu,Yu-Mi Kim,Rock-Bum Kim,홍영습 대한예방의학회 2011 Journal of Preventive Medicine and Public Health Vol.44 No.5

Objectives: This study investigated the relationship between the blood mercury concentration and cardiovascular risk factors in elderly Korean individuals living in coastal areas. Methods: The sample consisted of 477 adults (164 males, 313 females) aged 40 to 65 years who visited a Busan health promotion center from June to September in 2009. The relationship between blood mercury concentration and cardiovascular risk factors including metabolic syndrome, cholesterol profiles, blood pressure, body mass index (BMI),waist circumference and waist-to-hip ratio (WHR), was investigated. Variables related to blood mercury concentration were further evaluated using multiple regression analysis. Results: The blood mercury concentration of the study population was 7.99 (range, 7.60 to 8.40) ㎍/L. In males, the blood mercury concentration was 9.74 (8.92 to 10.63) ㎍/L, which was significantly higher than that in females (7.21, [6.80 to 7.64] ㎍/L). The blood mercury concentration of the study population was related to several cardiovascular risk factors including low-density lipoprotein (LDL) cholesterol (p=0.044), high-density lipoprotein (HDL) cholesterol (p=0.034), BMI (p = 0.006), waist circumference (p = 0.031), and WHR (p < 0.001). In males, the blood mercury concentration was significantly correlated with WHR in the multiple regression analysis. Conclusions: In males, the blood mercury concentration was related to waist-to-hip ratio, which is a central obesity index and cardiovascular risk factor. Our finding suggests that cardiovascular disease risk in males was increased by mercury exposure via an obesity-related mechanism.

Early Percutaneous Catheter Drainage Reduces Hospital Stay but Not Mortality in Patients with Pyogenic Liver Abscess

( Chang Hun Lee ),( Yun Chae Lee ),( Jaehee Park ),( Song Yi Yu ),( Hun Gil Jo ),( Jae Sun Song ),( Gum Mo Jung ),( Yong Keun Cho ),( Eun Young Cho ),( In Hee Kim ) 대한간학회 2020 춘·추계 학술대회 (KASL) Vol.2020 No.1

Aims: To investigate the factors associated with prolonged hospital stay and mortality among patients with pyogenic liver abscess (PLA) who underwent percutaneous drainage (PCD). Methods: We retrospectively reviewed data from PLA patients admitted from 2005 to 2018 at three tertiary hospitals in Jeonbuk province. We selected patients who underwent PCD during the admission period and early PCD was defined whether the procedure was done within 3 days of admission. Results: Among 655 patients diagnosed with PLA, 366 patients who underwent PCD were enrolled for the study. The patients had a mean age of 65.5 ± 14.7 years, and mean maximal diameter of the hepatic abscess was 6.1 ± 2.6 cm and 71.9% of the lesion was single. Next, two groups were divided depending on the time period of PCD and 269 patients (73.5%) underwent PCD within 3 days of hospitalization. In baseline characteristics, early PCD group was significantly higher in the number of abscess as well as the maximal abscess diameter. However, hospitalization period was significantly lower in the early PCD group though in-hospital mortality was not different. We checked laboratory results at 1 week after the admission and CRP levels were significantly lower in the early PCD group. We further analyzed the factors related to the long-term hospitalization more than 14 days. In multivariate analysis, underlying diabetes, lower albumin levels, and PCD inserted after 3 days of admission were independent factors associated with prolonged hospital stay. Conclusions: Early PCD facilitated improvement of inflammatory laboratory markers and shortened the hospital stay. Early PCD may be beneficial in patients with PLA.

Differential Effects of Fumonisin $B_1$ on Cell Death in Cultured Cells: the Significance of the Elevated Sphinganine

Yu, Chang-Hun,Lee, Yong-Moon,Yun, Yeo-Pyo,Yoo, Hwan-Soo The Pharmaceutical Society of Korea 2001 Archives of Pharmacal Research Vol.24 No.2

Fumonisins are specific inhibitors of ceramide synthase in sphingolipid metabolism. An alteration in sphingolipid metabolism as a result of fumonisin exposure is related to cell death (Yoo et al., 1992). The objective of this study was to investigate whether elevated free sphinganine levels are related to the sensitivity of cultured cells to fumonisin exposure. Fumonisin $B_1$ elevated the intracellular free sphinganine concentraions in both LLC-$PK_1$ and Chinese hamster ovary (CHO) cells. However, CHO cells are resistant to fumonisin cytotoxicity at 50${u}m$, while LLC-$PK_1$ cells are sensitive at concentrations greater than 357M. The intracellular concentration of free sphinganine in LLC-$PK_1$ cells treated at 50${u}m$ fumonisin $B_1$ for 72 h was approximately 1450 pmol/mg protein relative to the 37 pmol observed in the control culture. Under the same conditions, the population of apoptotic cells in the 50${u}m$ fumonisin $B_1$-treated culture was approximately 37% of the total compared to 12% in the control. The caspase III-like activity after 72 h in the 50${\mu}$M fumonisin $B_1$-exposed culture Increased to approximately 50 $pmol/mg$ protein/hr compared to 6 $pmol/mg$ protein/hr in the control. L-cycloserine, a serine palmitoyltransferase inhibitory reduced the fumonisin $B_1$-stimulated caspase III-like activity down to the control level. Under the same culture conditions, the intracellular concentration of free sphinganine after-cycloserine plus fumonisin $B_1$ treatment was 140 pmol/mg protein compared to 1450 $pmol/mg$ protein in fumonisin $B_1$ alone. The intracellular concentration of free sphinganine in CHO cells treated with 50${u}m$ fumonisin $B_1$ for 72 h was al)proximately 460 pmol/mg protein, indicating that the mass amount of elevated free sphinganine in the CHO cells was about 32% of that in LLC-$PK_1$ cells. Adding exogenous sphinganine to the CHO cells along with 50${u}m$ fumonisin $B_1$ treatment for 72 h caused both necrosis and apoptosis. In conclusion, the elevated endogenous sphinganine acts as a contributing factor to the fumonisin-induced cell death.
