金秀重,權宇鉉 慶北大學校 1983 論文集 Vol.35 No.-

A generalized image digitizer has been designed to accept a atandard NTSC video signal and to digitize an arbitrary selected window of a stationary image by the program. The digitizer has a maximum resolution 512×440 pixel, and each pixel has 256 gray level. The hardware is powerftl and is controlled by the software, so that it is connedted with any microcomputer or minicomputer. Tpe results are displayed on the CROMEMCO graphic terminal.

Of all forms of family violence, wife abuse ranks second, following child abuse, in terms of the attention it now receives in public, professional, and scientific communities. The purpose of this paper is to review what is known about prevalence of wife abuse, to summarize theories on what causes wife battering, to describe current treatment modes, and to highlight some premising future directions. The term battered women in this paper will be used to describe women who have experienced physically injurious behavior at the hands of their husbands. Theories of wife battering are organized around three different levels of explanation: intraindividual, social psychological, and sociocultural, Wife battering has physical and psychological impact on battered wives. A variety of intervention programs have been developed to combat wife abuse. Initial intervention programs aimed at combatting wife abuse focused on the women who were its victims and included shelters, hotlines, cirsis intervention programs, and counseling services for abused wives. In the second level prevention program, it is necessary to educate the community about wife battering and to alter the societal attitudes which support it. Also it is effective to have a programs for men who batter. Treatments focusing on skills development and behavioral changes include methods designed to improve the men's ability to reorganize their stressors and react to them differently. Educational programs for couples and processionals are need to be developed.

An internet broadcasting technology is to transmit various multimedia contents to a variety of customers on internet. It supports interactive services and on-demand services unlike TV broadcasting. In this paper, we study on the traffic agent systems for internet broadcasting. It requires to save backup path addresses for the efficiency and stable transmissions, The backup paths are searched on the same level in each node's parents level, If the node is not connected, the traffic agent connects primary node and backup paths rapidly. Proposed system can save the nodes for backup paths efficiently and reconstruct backup path rapidly.

만성화된 환자들이 주로 입원하여 있는 대형정신병원에서 수면제의 처방에 영향을 미치는 요소들을 조사해 보고자 하였다. 1996년 10월 2일 국립부곡정신병원에 입원해 있는 환자 402명을 대상으로 병록지조사를 통해 입원시부터 조사당일까지의 수면제 사용을 조사였다. 담당의사의 routine order에 의한 수면제 처방의 여부, 담당의사의 p.r.n. order에 의한 처방 여부, 당직의사에 의한 수면제 처방 여부를 조사하여 환자의 나이, 성별, 진단, 입원횟수, 유병기간, 담당의사의 정신과 근무 연수 등의 변수에 따라 비교해 다음과 같은 결과를 얻었다. 1) 207명(51.5%)이 재원기간동안 최소한 일회 이상 수면제를 복용하였고, 195명(48.5%)은 수면제를 복용한 적이 없었다. 2) 담당의사의 routine order에 의한 수면제 처방의 빈도는 남자에 비해 여자에서 높았다. 3) 담당의사의 routine order에 의한 수면제 처방의 빈도는 전문의가 담당의사인 환자군에서 높았다. 4) 담당의사의 p.r.n. order에 의한 수면제 처방의 빈도는 전공의 1년차가 담당하는 환자나 전문의가 담당하는 환자에서 높았다. 5) 연령, 진단, 유병기간, 입원횟수 등은 수면제 처방의 빈도와 유의한 관계가 없었다. 이상의 결과를 통해 국립부곡정신병원의 입원환자에서 수면제의 처방이 환자의 성별과 담당의사의 정신과 근무 연수와 관계됨을 알 수 있었다. The purpose of this study was to investigate the factors that were associated with the prescription of hypnotics in inpatients of a large mental hospital. The medical records were reviewed in 402 inpatients who were admitting in Bugok National Mental Hospital at October 2, 1996. The results were as follows: 1) Fifty-one percent of the whole group received a hypnotics at least once during hospitalization. 2) The prescription of hypnotics by routine order of doctor in charge was more frequent in female patients than male patients. 3) The prescription of hypnotics by routine order of doctor in change was more frequent in patients whose doctor in charge was a psychiatric specialist than patients whose doctor in charge was a psychiatric resident. 4) The prescription of hypnotics by p.r.n. order of doctor in charge was more frequent in patients whose doctor in charge was a first-year psychiatric resident or a psychiatric specialist than a second, a third, or a forth-year psychiatric resident. 5) Age, duration of illness, frequency of admission, and diagnosis were not significantly associated with frequency of hypnotics prescription. These findings suggest that the prescription of hypnotics in inpatients of Bugok National Mental Hospital was positively associated with patient's sex and duration of service of doctor in charge.

안수현,서근학,김병진 釜慶大學校 1998 釜慶大學校 論文集 Vol.3 No.2

Foam separation of microbial cell of the yeast Saccharomyces formosensis was investigated. A batch foam or continuous separator has been used to recover the yeast cells from the culture broth without the use of surfactant. In continuous experiments, the yeast concentration ratio was enhanced at low hydraulic residence time, high superficial gas velocity or low influent yeast concentration. And addition of Ca2+ also improved the concentration ratio. "The optimum pH and temperature for foam separation was the same as the optimum condition for ethanol production.

혐기성 소화의 동력학적 해석 : 有機酸 構成比에 따른 嫌氣性 消化 Anaerobic digestion with Component ratios of organic acids

노기현,장성호,안종수,전기일,김수생 동아대학교 환경문제연구소 1994 硏究報告 Vol.17 No.2

This research on organic acid and its component ratio (H_(AC) : H_(pt) : H_(Bu)) mainly produced in acid formation steps of anaerobic treatment process. From comparing the above experimental results with digestion efficiency of acetic acid used as substrates, I can find the conclusion as follows : 1. Removal efficiency for component ratios of organic acid is 64.3-98.6%, 59.6-98.2 %, respectively, varied with HRT of 3-20 days. 2. For l0days of HRT, in order to investigate the effects of component ratio of organic acid, when its component ratio(H_(ac) : H_(pt) : H_(bu)) is 100 : 0 : 0, 50 : 25 : 25, 28 : 38 : 34 and 0 : 50 : 50(as COD), respectively, effluent concentration is 464mg/l, 666mg/l, 832mg/l and 1,148mg/l, respectively. 3. Component ratio of menthane gas for organic acids represents 55-70%, with variation o: HRT, 3-20days. 4. When the component ratios of organic acid(H_(ac) : H_(pt) : H_(bu)) is 50 : 25 : 25 and 23 : 38 : 34(as COD), methane production per COD removal for HRT of 3-20days is 0.27~0. 32, 0.21~0.30. 5. From the mass balance relationship, when the component ratios of organic acid is 50 : 25 : 25 and 28 : 38 : 34(as COD), methane production ratio, varied with HRT of 3days, 5days, l0days, 15days and 20days in 49.6%, 66.4%, 77.5%. 85.1% and 89.7%, respectively and 39.1%, 56.3%, 68.3%, 76.3%, 83.9%, respectively.

The purpose of this study was to determine the usefluness of the UGI study with Carboxy-Methylcellulose (CMC) and 140% barium in the patient undergone gastrectomy We reviewed the UGI study with effervescent agent and barium and the UGI study with CMC and 140% barium of twenty one patients, undergone gastrectomy (Billroth-Ⅱ:12, Billroth-Ⅰ:4 total gastrectomy:5). The average interval between these studies was 19 months. The coating quality of the remnant stomach, anastomosis sit e, jejunum and proximal ileum in two studies were compared. The maximum luminal diameter of the same site and the maximum distance between a adjacent valvulae conniventes were measured for evaluating the distensibility of these studies. Compared with the coating quality of the remnant stomach, the UGI study with effervescent agent and barium was superior to the UGI study with C MC and barium in 68% (11/16) patients. The difference of coating quality between these studies was marginal in the anastomosis site and jejunum. The UGI study with CMC and barium provided a better coating quality in the proximal ileum of 95%(20/21). The maximum luminal diameter of the anastomosis site, jejunum and proximal ileum was respectively 2.75cm, 3.36cm, and 2.82cm inthe UGI study with effervescent agent and barium, 3.2cm 3.35cm, and 3.40cm in the UGI study with CMC and barium(p〈0.01). The maximum distance between a adjacent valvulae conniventes of the jejunum and proximal ileum was respectively 0.61cm and 0.51cm in the UGI study with effervesent agent and barium, 0.74cm and 0.72cm in the UBI study with CMC and barium (p〈0.05). Compared with the distensibility, the UGI study with CMC and barium was superior. The UGI study with CMC and barium in subjects, undergone gastectomy, showed the advantage the mucosa distal to anastomosis site except for the remnant stomach and must be supply the more information in finding lesion such as adhesion and peritoneal dissemination.
