손희정,김형석,송영채,성낙창,김수생,Son, Hee-Jeong,Kim, Hyeong-Seok,Song, Young-Chae,Sung, Nak-Chang,Kim, Soo-Saeng 유기성자원학회 1996 유기물자원화 Vol.4 No.2

본 연구에서는 피혁슬러지의 부숙기간별 이화학적 변화를 측정하고 이를 근거로 지렁이의 생존율, 증체량, 부화율 등을 조사함으로서 지렁이를 이용한 안정화 및 처리, 처분 가능성을 평가하였다. 지렁이의 급이 조건에 적합한 피혁슬러지의 부숙기간은 산화환원전위(Eh), 알카리도에 대하여 각각 30일, 35일로 평가되었으며, 부숙기간동안 피혁슬러지의 pH 역시 초기 7.8에서 지렁이의 생육에 적합한 중성영역으로 점차 변화하는 경향을 보였다. 50일 부숙시킨 피혁슬러지의 이화학적 특성은 pH는 7.1, Eh는 85mV, 알카리도는 450ppm $CaCO_3$로 조사되었으며, 중금속함량은 여러 기준치를 만족하는 것으로 평가되었다. 50일 부숙시킨 피혁슬러지에서 지렁이 생존율은 $20{\sim}25^{\circ}C$의 생육온도에서 75%, 증체율은 230%, 부화율은 87%의 값을 보였다. 이상의 결과로부터 피혁슬러지는 최대 50일의 부숙기간을 거칠 경우 지렁이를 이용한 퇴비화가 가능한 것으로 평가되었다. The study on the ripening of leather waste sludge was performed to vemistabilize the sludge effectively using a laboratory scale darkened wood box reactor ($10{\times}10{\times}20cm$). The acceptable feed conditions for earthworm of Eh, alkalinity were obtained in the 30th and 35th days, respectively. The value of pH was gradually decreased from 7.8 to 7.1 through the ripening time. The contents of heavy metals of the ripened sludge were estimated as lower levels compared to the other regulatory standards for compost. After the ripening time for 50days, the physico-chemical properties of the sludge were estimated as pH 7.1, water content 72%, redox potential 85mV, electrolytic conductivity $2,620{\mu}mhos/cm$ and alkalinity 450 ppm as $CaCO_3$, respectively. In the ripened sludge, survival rate of the earthworms for 50 days was about 75%, and the live weight increase rate was about 230% at the temperature range of $20{\sim}25^{\circ}C$. Moreover, hatching rate of the earthworm cocoons was about 87% and the highest value was obtained in the 20~30th days. From the above results, it was evaluated that leather waste sludge could be vermistabilized effectively by earthworms, when the sludge was ripened during 50 days.

유색미 겨 아라비녹실레인과 지구성 운동트레이닝이 LPS 처치된 흰쥐의 TLR4 Signaling 단백질 발현에 미치는 영향

손희정,Son, Hee-Jeong 한국식품영양학회 2014 韓國食品營養學會誌 Vol.27 No.6

The purpose of this study is to investigate the effects of arabinoxylan rice bran and endurance exercise training on TLR4 mediated protein expression in LPS-treated rats. The results showed that TLR4 as an important protein in the inflammatory response against lipopolysaccharide was shown to be significantly lower in both arabinoxylan supplement with exercise group and exercise group, thus the arabinoxylan rice bran had a higher inhibitory activity than arabinoxylan supplement group. However, $NF-{\kappa}B$ and MyD88 protein expression was not changed in arabinoxylan supplement with exercise training group, whereas $NF-{\kappa}B$ significantly decreased in 4 weeks of exercise training group. These results suggest that the supplement of arabinoxylan rice bran with exercise is likely to contribute to inflammation response and the arabinoxylan rice bran can be used as a possible safe alternative to the immunotherapeutic intervention.

Today, China is drawing the attention of the entire world with rapid economic growth that commenced with the opening of its economy. The world recognizes the value of China as a massive market that will eventually lead the global economy in the future. This paper is devoted to basic research on Chinese apparel consumers and is intended to help apparel market developments in China. Its aim is to understand the distinct characteristics of China and to study general apparel designs and purchasing preferences necessary for the development of products that can meet the special needs of Chinese consumers. In addition it identified clothing behaviors to better understand the distinct characteristics of Chinese female college students preferences. The research showed that Chinese female college students preferred achromatic, dark blue, and red colors in decreasing order, and cotton and wool textiles. For style, they preferred designs that accentuated individuality. Also, comfort played an important role in purchasing. Behaviorally, they had strong interests in fashion but valued economic and pragmatic aspects when it came to purchasing, and were not much affected by the desire for identification. From research results, the paper concludes that there is a need for developing comfort-enhancing products for highly individual Chinese female college students, with designs uniquely preferred by them, and valueadded apparel products targeted for upper social levels.

본 연구는 절차기술의 객관구조화 진료시험(Objective Structured Clinical Examination)에서 표준화환자가 평 가자의 역할을 수행할 수 있는지 알아보기 위해 신뢰도를 평가하는데 그 목적이 있다. 시험의 주제는 남성 도뇨관 삽관과 창상드레싱 2가지로 정하고, 2년 이상의 객관구조화 진료시험 채점 경력이 있는 표준화환자와 교수 각 4명을 2명씩 짝을 지워 한 주제 당 표준화환자 그룹과 교수 그룹이 동시에 채점하게 하였다. 표준화환자들에게는 술기의 정의, 방법, 주의점, 후유증에 대한 교육이 이루어졌으며 동영상이 포함된 강의, 교수의 시연 후 표준화환자가 직접 실습해보고 교수로부터 되먹임을 받는 순서로 총 8시간( 주제당 4시간)의 교육이 시행되었다. 8명의 평가자 모두 객 관구조화 진료시험 전날 모여 기존의 동영상자료를 이용한 가상 채점으로 1시간동안 채점 표준화를 이루었다. 채점 표는 체크리스트 14문항과 총괄평가 1문항으로 이루어졌다. 한 학생당, 주제당 5분간의 시험 후 2분간의 평가가 이 루어졌다. 표준화환자와 교수간의 분석은 GENOVA program을 이용하였다. 연구 결과 주제 전체에서 G상수는 0.839, 평가자의 신뢰도는 0.946으로 매우 높았다. 표준화환자그룹과 교수그룹 사이의 평가자간 일치도는 체크리스트에서 0.949, 총괄평가에서 0.908이었다. 따라서 적절한 교육이 선행되어진다면 표준화환자도 절차기술의 객관화진료시험에 신뢰할 만한 평가자로 이용되어질 수 있을 것이다. The purpose of this study is to investigate whether standardized patient(SP) can be used as a reliable examiner in Objective Structured Clinical Examination(OSCE). 4 SPs and 4 faculties who have more than 2 years experience of OSCE scoring were selected. For 1 assignment 2 members of faculty and 2 SPs were designated as raters. SPs were educated for assessing 2 technical skills, male Foley catheter insertion and wound dressing, for 8 hours (4 hours / day, each topic). The definition, method, cautions and complications for each of procedural skills were covered in the education. Theoretical lectures, video learning, faculty demonstration and practical training on mannequins were employed. The 8 raters were standardized for an hour with simulated OSCE scoring using previous videos on the day before the OSCE. Each assessment was composed of 14 checklists and 1 global rate. The allotted time for each assignment was 5minutes and for evaluation time 2 minutes per student. The evaluation from the faculty and SPs were compared and analyzed with the GENOVA program. The overall generalizability coefficient (G coefficient) was 0.839 from two cases of OASTS. The reliability of the raters was high, 0.946. The inter-rater agreement between faculty group and SP group was 0.949 for checklist and 0.908 for global rating. Therefore SPs can play a role of raters in OSCE for procedural skills, if they are given the appropriate training.

The mucin-producing tumor of the pancreas is characterized by an enlarged papilla with a dilated orifice and visible mucin oozing through the orifice on endoscopy. Since Ohhashi e.t al reported four unique cases with above characteristics in 1982, more than 50 cases of mucin-producing pancreatic cancer have been reported in Japan. It has been recognized that not only carcinoma but also benign lesions can produce these features. The number of patients with cystic neoplasm in pancreas is increasing because of recent developments in irnage diagnostic techniques but the classifications are still controversial. Recently, a new entity, the ductectatic type of mucinous cystadenoma was reported sporadica]ly in Japan. Papillary cystic neoplasm has been described recently as indicating a favorable prognosis and a rare recurrence following resection. We reported a 63-year-old female diagnosed as the ductectatic type of adenocarcinoma of the pancreas. Abdomen CT and ultrasonography revealed about 3 cm sized mass with multiloculated cystic nature at the head of the pancreas. Enlarged papilla with expelled mucin from a petulous orifice was noted on duodenoscopy. Endoscopic retrograde pancreatograrn showed the clilated rnain pancreatic duct with grapelike c]usters. Under the clinical diagnosis of mucin producing cystadeno- carcinoma, Whipp]es operation was performed. The resected specimen showed il] defined infiltrated gray solid tumorous lesion which was tightly attached to the duodenal 1st portion Microscopic finding showed moderately differentiated ductal adenocarcinoma of the pancreas.

의전원 4학년 학생의 과정기술 객관구조화진료시험에 도입된 시뮬레이션의 충실도에 따른 인식 변화

손희정(Son, Hee-Jeong),김진욱(Kim, Jin-Uk),이유리(Lee, You-Ri),황병문(Hwang, Byeong-Moon) 한국산학기술학회 2012 한국산학기술학회논문지 Vol.13 No.3

본 연구는 마취과 임상실습을 마친 의전원 4학년 학생들을 대상으로 충실도를 달리한 과정기술 객관구조화 진료시험에서 보여지는 자기평가와 학습동기의 변화 유무를 비교해 보고자 시행되었다. 학생들을 무작위로 두 군으로 나누어 HF군에서는 고충실도의, LF군에서는 저충실도의 과정기술 객관구조화진료시험을 시행하였다. 사례는 기관삽 관과 정맥관삽관의 두 주제로 임상술기교육을 맡은 책임교수가 개발한 후 다른 두 교수가 검토, 수정하였다. 두 주제 에 대해 고충실도 사례는 실제 수술실에서 in-situ 시뮬레이션으로, 저충실도 사례는 일반 교실에서 단순과업모형을 이용하여 충실도만 달리하여 시행하였다. 학생들은 수행 전 후로 5점 척도로 구성된 설문조사에 응하였고, 자료의 분 석은 Man-Whiteney test와 Paired T-test를 이용하였다. 연구 결과, 의전원 4학년 학생들의 술기 수행능력에 대한 자기 평가는 저충실도 사례보다 고충실도 사례에서 평가 전에 보여준 자신감보다 낮게 평가되었고, 고충실도 사례 후에 연 습의 필요성을 더 느꼈다. 고충실도 사례의 도입은 학생들의 술기연습에 대한 동기 부여에 도움이 될 것으로 여겨지 지만 경제적인 효율도 고려해야 할 것이다. The 4th year medical students were randomly divided and designated as group HF and LF, representing high and low fidelity simulations respectfully. Both groups performed OSCE on 2 topics(adult intubation and IV cannulation) with each composed of the same scenario. Each scenario was developed by a faculty in charge of clinical skill education with supervision from 2 other faculty members. High fidelity simulations were designed as in-situ simulations in real OR. Low fidelity simulations had the same scenarios but the environment was simulated only with a simple task trainer in the classroom. All students participated in series of survey using a Likert scale before and after the simulations. The provided data was anlayzed with paired T-test and Mann-Whiteney test(p<0.05). The post simulations self evaluation score for group HF was lower than pre-simulation self confidence score for both topics of adult intubation and IV cannulation where as for group LF, it was lower only for adult intubation(p<0.05). In group HF, the needs for clinical training on both topics increased after the simulation. In group LF, there was no significant change of needs for clinical training between pre and post simulation survey. This suggest that fidelity may be a helpful factor to improve the motivation of the students and further study on economical aspect should be addressed.

Knee osteoarthritis is a common cause of disability and a primary reason for knee joint replacement in the elderly. Exercise is important for managing the functional limitations associated with joint disease. The purpose of this study was to examine the effect of 4 week rehabilitation exercise program (3 times/d) on pain scale and muscular functions. Fifteen elderly women (61-69 years) with knee osteoarthritis were participated in this study. They performed 4 week rehabilitation exercise program (isometric, isotonic and isokinetic) and undertook muscle strength tests and a pain rating scale test before and after the rehabilitation program. From the results of this study, we confirmed the pain intensity was decreased (p<.001, 32%) and isokinetic variables were improved. The peak torque in extensor and flexor muscle at 60°/sec and 180°/sec were increased(p<.05). The total work done was increased in extensor and flexor muscle at 240°/sec(p<.01). These results suggest the 4 week rehabilitation exercise program in this study was effective on pain intensity and muscular functions in the elderly women with knee osteoarthritis.
