본 연구는 음식물류 폐기물 공공 자원화 시설 운영의 문제점과 제도 개선방안을 위하여 실시하였다. 기존 음식물류 폐기물 공공자원화 시설에 대한 실태조사를 통해 운영에 따른 문제를 분석하였으며, 이를 위하여 음식물류 폐기물의 발생량 및 자원화 현황, 공공 및 민간 자원화시설 현황, 전국의 주요 음식물류 폐기물 공공자원화 시설의 실제 운영과정에서 나타난 문제점을 분석한 결과는 다음과 같다: 현재 국내 음식물류 폐기물의 분리 수거량은 약 97%인 것으로 나타났다. 그리고 대부분의 공공 자원화시설은 음식물류 폐기물의 자원화가 아닌 단순처리에 급급한 것으로 나타났으며 경제성도 없는 것으로 분석되었다. 특히, 바이오가스시설 대부분은 실시설계와는 달리 가스 생산량 및 수요량이 전혀 맞지 않는 것으로 나타났다. This study is conducted to find out problems of the public food waste recycling facility and its improvement. Through a research on the actual condition, it is possible to analyze the problem of operation. Moreover, for this improvement, with analysis of the current state of recycling rate including its generation and the problem that can be shown from the real operation of the public/private food waste recycling facility, the results are as follows: It can be shown that the current amount of domestic food waste resource recycling is about 97 %. Almost every public recycling facility is analyzed to be economically infeasible and is not for recovery but to simple disposal. Especially, most of Biogas facilities appeared that amount of production and demand is not appropriate differed from enforcement design.

Polymerase chain reaction (PCR) is the most sensitive and rapid method for the diagnosis of M.tuberculosis infection. Many reports have shown different methods for mycobacterial DNA extraction, but revealed many differences in simplicity and time-consumption. We studied which method was the best among 7 different ones for DNA extraction from 32 smear-positive sputa, using PCR of targeting 123bp DNA fragment of IS6110. The methods were the following : SDS-Microwave oven method, NaOH Lysis method, Triton X-100, Proteinase K method, Lysis buffer method. SDS-Proteinase K method, Bead Beater method, and Bead Beater/CTAB method. The amplification products were identified by electrophoresis on ethidium bromide-stained agarose gels, and confirmed by restriction enzyme, Southern blot hybridization, and DNA sequencing. All 32 cases were positive (100%) by the 7 different methods. It took 1 hour or more to detect DNA in SDS-Microwave oven method, NaOH Lysis method, and Bead beater/CTAB method. It took 2 hours or less in the others. SDS-Proteinase K method and Bead Beater/CTAB method were simpler and more convinient than the others. These results suggest that SDS-Proteinase K method and Bead Beater/CTAB method might be better than the others for the extraction of mycobacterial DNA in terms of simplicity and time-consumption, although all the methods were sensitive.

본 연구는 음식물류폐기물 공공 자원화 시설 운영의 문제점과 제도 개선방안을 위하여 실시하였다. 현재 운영중인 음식물류 폐기물의 가동율 현황과 자원화 시설의 확충 계획에 대한 분석을 통해 시설의 무분별한 신규건설로 인한 국가의 예산이 낭비되지 않도록 그 대안을 제시하였으며, 그 결과는 다음과 같다. 공공 자원화시설 신규 확충보다는 기존 민간 자원화시설을 활용하여 예산을 절약하고 음식물류 폐기물의 안정적인 처리는 물론 자원순환을 촉진시킬 수 있는 정책전환이 필요하다. 음식물류 폐기물을 친환경적인 방법으로 안정적으로 처리하기 위해서는 제도개선이 필요하며, 이를 위해 민간 자원화시설 가동률 저하를 줄일 수 있는 준공영제 도입이 필요하다. 또한, 공공 자원화시설의 검증된 기술과 경제성 확보 방안 마련이 필요하다. This study is conducted to find out the problems of the public food waste recycling facility operation and its improvement. In order to save the national budget by analyzing plans to expand including operation rate for the food waste recycling facility, the alternative ways are suggested. The result can be as follows: Policy switch is required not only to save budget and stable disposal of food waste but also to promote resource recycling rather than expanding public facilities. In order to change the policy for stable and eco-friendly disposal of food waste, it is necessary to adopt semipublic system that prevent the decline of the rate of operation of private resource recycling facility. Furthermore, it is required to prepare both qualified technologies of public resource recycling and the ways of profitability secure.

후두 마스크는 기관 내 삽관 튜브와 비교하여 식도 운동에 유의한 영향을 미치는가 ?

손용,박수경,김정훈,윤재승,김태요,정영표,김향이 대한마취과학회 2002 Korean Journal of Anesthesiology Vol.42 No.2

Background : To know whether the laryngeal mask airway (LMA) triggers a pharyngo-esophago-gastric reflex during general anesthesia, we compared the esophageal motility of patients with an LMA or endotracheal tube (ETT) in place. Methods : Fifty patients (ASA Ⅰ or Ⅱ) scheduled for elective orthopedic surgery with general anesthesia were randomly allocated into LMA (n = 30) or ETT (n = 20) groups. The esophageal manometric inputs were recorded continuously using an ambulatory esophageal manometric recorder and divided into five perioperative phases (preanaesthesia, induction, operation, LMA or ETT rejection, and arousal phase). Results : The peristaltic percent and number of contractions per minute were significantly decreased during induction, operation, LMA or ETT rejection and arousal phases compared with preanesthetic phases in both the LMA and ETT groups. However, there were no significant group differences in any corresponding perioperative phases. Conclusions : We suggest that during general anesthesia the use of a LMA does not provoke significantly different esophageal peristalsis compared with an ETT. Thus, the LMA is unlikely to potentiate gastric regurgitation and reflux during general anesthesia by stimulating the pharyngo-esophago-gastric reflex. (Korean J Anesthesiol 2002; 42: 141~147)

김주옥,홍석철,한표성,이종진,김선영,이영하,신대환 충남대학교 의과대학 지역사회의학연구소 1994 충남의대잡지 Vol.21 No.1

Background: Pneumocystis carinii (PC) is a opportunistic pathogen causing serious pneumonia (Pneumocystis carinii pneumonia : PCP) in immunosuppressed patients including AIDS. Laboratory diagnosis of PCP is dependent on microscopic demonstration of the PC by using cytochemical staining or by immunocytochemical staining with monoclonal antibodies. However, these staining methods are not highly sensitive. The development of the polymerase chain reaction (PCR) has made it possible to detect very small numbers of pathogens in clinical specimens. To establish the usefulness of PCR for detection of PC DNA, We performed PCR as a pilot study. Methods: PCP was induced on Spraque-Dawley rats with prednisolone 5mg IM twice a week. Bronchial lavages, impression smears, and permanent sections were performed from the 3rd week to 7th week of cortisonized rats. PC DNA was extracted with bead beater / 10% CTAB method. Results: Impression smears showed PC cyst after the 4th week (100%, 28/28 rats), and permanent sections showed 27/28 rats. Control rats showed some PC cysts (2/7). PCR result was positive only one case among the 6th week rats (1/7), But positive 6 cases at the 7th week rats, (6/7). Among control rats. 2 cases were positive (2/7). ??This data is a pilot study for the PC DNA detection using a PCR. PCP were successfully cortisonized rats. If adequate bronchial washing technique will be used, PCR can be a sensitive for PC DNA detection.

The purpose of this study is to find to relationship among the children's peer status, friendship quality, and conflict resolution strategie in children's friendship. The object of this study were 417 children in 5th grade of elementary school in Seoul. The measuring instruments used for study were peer nomination developed by Coie and Dodge(1983), Friendship Quality Scale developed by Lee and Koh(1999) and a Scale on Friendship Conflict Resolution Strategies (Rhee, Koh & Oh, 2000). The Collected data was analyzed by SPSSWIN statistical program. The frequency and percentage were calculated to investigate the general characteristics of the subjects. One-Way analysis was performed to find relationship among the children's peer status, friendship quality Mutiple Regression was performend to find relationship among the children's peer status, friendship quality, and conflict resolution strategie in children's friendship. The major results of this study are as follows, First, concerning about peer status and friendship quality, pouplar group have a positive friendship but, rejected group have a conflictive friendship. Second, while popular group used various strategy in conflict resolution, neglected group used evasive strategy. Third, concerning about relation between quality of friendship and frienship conflict resolution strategy, while the group which has high degree of emotional stability, intimacy and human desire used negotiation, cooperation and concession strategy, the group with has low degree of cooperation and pleasure of friendship used evasion and away strategy. Fourth, concerning the effect of friendship quality according to peer status which influence conflict resolution strategy between friendship, each popular, average, rejected and neglected group gas different quality of friendship and according the lower factor of friendship quality, each group has different conflict resolution strategy. Therefore I suggest that according to the peer status, arbitration program should be selected with propriety.

Microsatellite Instability Is Associated with the Clinicopathologic Features of Gastric Cancer in Sporadic Gastric Cancer Patients

Shin Hyuk Kim,Byung Kyu Ahn,남영수,Joo Youn Pyo1,Young Ha Oh1,이강홍 대한위암학회 2010 Journal of gastric cancer Vol.10 No.4

Purpose: Replication error is an important mechanism in carcinogenesis. The microsatellite instability (MSI-H) of colorectal cancers is associated with the development of multiple cancers. The influence of MSI-H on the development of multiple gastric cancers in sporadic gastric cancer patients has not been defined. This study was performed to reveal the association between the clinicopathologic features and MSI in sporadic gastric cancers. Materials and Methods: Between July 2004 and March 2009, the clinicopathologic characteristics, including MSI status, were evaluated in 128 consecutive patients with sporadic gastric cancers. None of the patients had hereditary non-polyposis colorectal cancer of familial gastric cancer. The markers that were recommended by the NCI to determine the MSI status for colorectal cancers were used. Results: MSI-H cancers were found in 10.9% of the patients (14/128). Synchronous gastric cancers were shown in 4 patients (3.1%). Synchronous cancers were found in 2 of 14 patients with MSI-H gastric cancer (14.3%) and 2 of 114 patients with MSS gastric cancer (1.8%; P=0.059, Fisher's exact test). Among the patients with synchronous cancer 50% (2/4) had MSI-H cancer, but 9.7% of the patients (12/124) without synchronous cancer had MSI-H cancer. MSI-H (RR, 24.7; 95% CI, 1.5~398.9; P=0.024) was related with to synchronous gastric cancer, but age, gender, family history, histologic type, location, gross morphology, size, and stage were not related to synchronous gastric cancer. Conclusions: MSI is associated with the intestinal-type gastric cancer and the presence of multiple gastric cancers in patients with sporadic gastric cancer. Special attention to the presence of synchronous and the development of metachronous multiple cancer in patients with MSI-H gastric cancer is needed.
