Objective : The current study investigated the prevalence and clinical characteristics of sexual exhibitionism and frotteurism, which was conducted for the first time in Korea. Methods : Among 568 total subjects (mean age $19.28{\pm}5.0$ year), 109 were victims of sexual exhibitionism (19.2%, VSE) of which 57 were females (91.9 percent) ; and 57 were victims of sexual frotteurism (10.9%, VSF) of which 57 were females (91.9%). The participants completed the self-reported scale for epidemiological and clinical characteristics. Results : Incident frequencies of above two times of VSE and VSF were 49 (50.0%) and 20 (32.3%), respectively. Incident locations of VSE were school/office 37 (33.3%), street 28 (25.6%), and near home 20 (18.3%). Also, incident locations of VSE were inside of bus 12 (19.3%), subway 12 (19.3%), subway/bus station 8 (12.9%), near home 8 (12.9%), and school/office 7 (11.3%). Notifying rate of VSE and VSF to the police were 7.3% and 0%, respectively. Also, notifying rate of VSE and VSF to family or friends were 72.5% and 58.1%, respectively Conclusion : These results suggested that VSE and VSF had a common prevalence, which could be different from behavioral and emotional characteristics of a control group ; and the victims were shown to require an active intervention by supportive social system.

In the results of monitoring nitrate concentration in more than 8,000 groundwater wells around agro-livestock, the average and maximum nitrate concentration was 9.4 mg/L and 101.2 mg/L, respectively. Since about 31% of the monitoring wells was exceed the quality standard for drinking water, nitrate control such as remediation or source regulation is required to conserve safe-groundwater in South Korea. Typical nitrate-treatment technologies include ion exchange, reverse osmosis, and biological denitrification. Among the treatment methods, biological denitrification by indigenous microorganism has environmental and economic advantages for the complete elimination of nitrate because of lower operating costs compared to other methods. Major mechanism of the process is microbial reduction of nitrate to nitrite and nitrogen gas. Three functional genes (nosZ, nirK, nirS) that encode for the enzyme involved in the pathway. In this work, we tried to develop simple process to determine possibility of natural denitrification reaction by monitoring the functional gene. For the work, the functional genes in nitrate-contaminated groundwater were monitored by using PCR with specific target primers. In the result, functional genes (nosZ and nirK) encoding denitrification enzymes were detected in the groundwater samples. This method can help to determine the possibility of natural-nitrate degradation in target groundwater wells without multiplex experimental process. In addition, for field-remediation application we selected nitrate-contaminated site where 200~600 mg/L of nitrate is continuously detected. To determine the possibility of nitrate-degradation by stimulated-natural attenuation, groundwater was sampled in two different wells of the site and nitrate concentration of the samples was 300 mg/L and 616 mg/L, respectively. Fumarate for different C/N ratio was added into microcosm bottles containing the groundwater to examine denitrification rate depending on carbon concentration. In the result, once 1.5 times more than amount of fumarate stoichiometry required was added, the 616 mg/L of nitrate and 300 mg/L of nitrate were completely degraded in 8 days and 30 days. The nitrite, byproduct of denitrification process, was also completely degraded during the experimental period.

A 1.28 L-batch reactor and continuous-flow stirred tank reactor (CFSTR) fed with formate and trichloroethene (TCE) were operated for 120 days and 56 days, respectively, to study the effect of formate as electron donor on anaerobic reductive dechlorination (ARD) of TCE to cis-1,2-dichloroethylene (c-DCE), vinyl chloride (VC), and ethylene (ETH). In batch reactor, injected 60 ${\mu}mol$ TCE was completely degraded in the presence of 20% hydrogen gas ($H_2$) in less than 8 days by anaerobic dechlorination mixed-culture (300 mg-soluble protein), Evanite Culture with ability to completely degrade tetrachloroethene (PCE) and -TCE to ETH under anaerobic conditions. Once the formate was used as electron donor instead of hydrogen gas in batch or chemostat system, the TCE-dechlorination rate decreased and acetate production rate increased. It indicates that the concentration of hydrogen produced in both systems is possibly more close to threshold for homoacetogenesis process. Soluble protein concentration of Evanite culture during the batch test increased from 300 mg to 688 mg for 120 days. Through the protein monitoring, we confirmed an increase of microbial population during the reactor operation. In CFSTR test, TCE was fed continuously at 9.9 ppm (75.38 ${\mu}mol/L$) and the influent formate feed concentration increased stepwise from 1.3 mmol/L to 14.3 mmol/L. Injected TCE was accumulated at 18 days of HRT, but TCE was completely degraded at 36 days of HRT without accumulation of the injected-TCE during the left of experiment period, getting $H_2$ from fermentative hydrogen production of injected formate. Although c-DCE was also accumulated for 23 days after beginning of CFSTR operation, it reached steady-state in the presence of excessive formate. We also evaluated microbial dynamic of the culture at different chemical state in the reactor by DGGE (denaturing gradient gel electrophoresis).

Nitrate is on the most seriou pollutant encountered in shallow groundwater aquifer in agricultural area. There are various remediation technologies such as ion exchange, reverse osmosis, and biological denitrification to recover from nitrate contamination. Biological denitrification by indigenous microorganism of the technologies has been reviewed and applied on nitrate contaminated groundwater. In this work, we selected the site where the annual nitrate (NO₃⁻) concentration is over 105 mg/L and evaluated denitrification process with sampled soil and groundwater from 3 monitoring wells (MW4, 5, 6). In the results, the nitrate degradation rate in each well (MW 4, 5, and 6) was 25 NO₃⁻ mg/L/day, 6 NO₃⁻ mg/L/day, and 3.4 NO₃⁻ mg/L/day, respectively. Nitrate degradation rate was higher in batch system treated with 2 times higher fumarate as carbon source than control batch system (0.42M fumrate/1M NO₃⁻), comparing with batch system with soil sample. This result indicates that increase of carbon source is more efficient to enhance denitrification rate than addition of soil sample to increase microbial dynamics. In this work, we also confirmed that monitoring method of functional genes (nirK and nosZ) involved in denitrification process can be applied to evaluated denitrifcation process possibility before application of field process such as in-situ denitrification by push-pull test.

To stress the importance of privacy in social networking, I presented an analysis on how information control and information management vulnerability influence trust and privacy concerns in social networking, and how trust and privacy concerns influence the sustainable usage intention of social network services. I also analyzed the factors affecting privacy concerns to present the method to alleviate social network users' concerns about privacy. Information collection control, information processing control and information management vulnerability were chosen and analyzed as the factors affecting privacy concerns. The results showed that information collection control and information management vulnerability significantly affected trust and privacy concerns; and information processing control did not significantly affect privacy concerns. The relationship between trust and privacy concerns, and sustainable usage intention was statistically significant; and the relationship between trust and expansion of communication channels was also statistically significant.

중국 조선산업의 경쟁력 강화를 위한 산업정책변화 고찰

박선화(Park, Sun-Hwa),두보(Tu, Bo) 대한중국학회 2017 중국학 Vol.60 No.-

본 논문은 포터(Porter)가 제시한 요소조건, 수요조건, 연관·지원 산업 실태 및 기업 전략, 구조 및 경쟁관계를 토대로 중국 조선산업에 관련한 현황을 고찰하였다. 또한 중국 정부의 조선산업에 대한 지원전략과 정책 특성을 분석하였다. 일본과 한국의 사례와 비교하면 중국은 부실기업을 정리하고 우수기업을 더욱 지원하는 ‘선택과 집중’ 이라는 전략으로 조선산업 지원정책을 추진하고 있다. 조선산업에 대한 한·중·일의 위기 극복 노력은 모두 정부주도로 추진되어왔으며, 조선산업의 특징을 고려하여 볼 때 정부의 지원은 산업의 국가경쟁력을 강화하는 데에 매우 중요한 역할을 한다. 중국은 조선산업의 구조조정 지원정책을 통해 동종기업 간 경쟁관계를 형성하고 전․후방 산업간 연계된 지원전략을 통한 산업의 활성화를 유도하였다. 이는 조선산업의 질적 선진화와 지속가능한 산업구조 구축으로 이어져 외부 위기에 강한 경쟁력을 갖출 수 있는 산업 으로 발전할 수 있게 할 것이다.

Diabetic hyperglycemia induces transient ischemia in the neural retina. High level of extracellular glutamate resulting from ischemia, in turn, influences on glutamate homeostasis. The present study has been conducted to clarify the alteration of the glutamate homeostasis-associated substances in the retinal Müller cells in response to a diabetic injury by streptozotocin injection. Young adult Sprague-Dawley rats were injected with streptozotocin (60 mg/kg body weight in 0.05 M sodium citrate buffer, pH 5.5) under anesthesia with 4% chloral hydrate. Animals above 300 mg/dl in blood glucose level were cared for 1, 4, 12 and 24 weeks, respectively. At each time-point, the retinas were dissected out and processed for immunohistochemical and immunoblotting analyses by using guinea pig anti-GLAST and mouse anti-glutamine synthetase (GS) antibodies. In the normal retina, GLAST and GS were immuno-localized in the Müller cells, the outer plexiform layer (OPL), the border between the inner nuclear layer and the inner plexiform layer (IPL), a band in the middle of the IPL, and the border between the IPL and the ganglion cell layer. The expression of both proteins was decreased remarkably in the OPL by 12 weeks of diabetes and increased slightly in the end feet of the Müller cells from 4 weeks onwards. Immunoblotting results of the two proteins in the diabetic retinas were largely consistent with those of immunohistochemistry. These results suggest that the alteration of glutamate homeostasis in the diabetic state is initiated mainly in the OPL by decreasing the uptake of glutamate via down-regulated GLAST. 당뇨병에 의한 고지혈증은 신경망막에 일시적인 허혈을 초래하며, 허혈에 의한 세포밖 glutamate 농도의 상승은 계속해 서 glutamate 항상성에 영향을 미친다. 본 연구는 부챗살아교세포에 존재하는 glutamate 항상성 관련물질이 당뇨병 상해에 대하여 또한 당뇨병 경과시기에 따라 어떤 반응을 나타내는가를 확인하기 위하여, 흰쥐를 실험동물로 하여streptozotoci을 정맥 내 주사한 후 1주, 4주, 12주 및 24주 경과한 당뇨병 망막을 대상으로 glutamate운반물질(GLAST) 및 glutamine합성효소 (GS)에 대한 항체를 이용한 면역세포화학법 및 immunoblot법을 시행하여 이 물질들의 변화를 비교 관찰하였다. 정상 망막에서 GLAST 및 GS 면역반응성은 부챗살아교세포의 세포체와 부챗살돌기, 바깥얼기층 및 속얼기층 중에서 속핵층과 속얼기층의 경계부위, 속핵층의 가운데 및 속얼기층과 신경절세포층의 경계부위 등 세 곳의 띠에서 나타났다. 장기간의 당뇨병 망막에서 망막의 두께가 감소하였고, 두 단백질은 당뇨병 유발 후 12주 망막의 바깥얼기층에서 현저하게 감소하였으며, 부챗살아교세포의 종말발에서 당뇨병 유발 4주 후부터 약간 증가하는 추세를 나타냈다. 정량적인 분석 결과 두 단백질은 당뇨병 유발 후 경과시기에 따라 점차 감소하는 경향을 나타냈다. 이상의 결과로 미루어 당뇨병 상태에서 망막내 glutamate 항상성의 변화는 바깥얼기층에서 GLAST의 발현 저하로 glutamate의 흡수(또는 제거)가 감소하면서 시작되며, 장기간의 당뇨병 망막에서 층의 두께 변화가 있는 점으로 보아 GLAST 및 GS의 발현 저하가 일부 흥분성 세포독성에 기여하는 것으로 생각된다.
