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.

The electrolyte in the solid oxide fuel cell must be dense enough to avoid gas leakage and thin enough to reduce the ohmic resistance. In order to manufacture the thin and dense electrolyte layer, 8 mol% $Y_2O_3$ stabilized-$ZrO_2$ (8YSZ) electrolyte layers were coated on the porous tubular substrate by the novel vacuum slurry dip-coating process. The effects of the slurry concentration, presintering temperature, and vacuum pressure on the thickness and the gas permeability of the coated electrolyte layers have been examined in the vacuum slurry coating process. The vacuum-coated electrolyte layers showed very low gas permeabilities and had thin thicknesses. The single cell with the vacuum-coated electrolyte layer indicated a good performance of $495\;mW/cm^2$, 0.7 V at $700^{\circ}C$. The experimental results show that the vacuum dip-coating process is an effective method to fabricate dense thin film on the porous tubular substrate.

손희정,김광점,Son, Heejung,Kim, Kwang-Jum 한국병원경영학회 2017 병원경영학회지 Vol.22 No.3

Purpose: Crisis is inevitable to every organization and therefore, successful crisis management is critical to the organizations' survival and prosperity. With the understanding, this study aims to draw propositions for successful crisis management of hospitals when facing infectious disease outbreak. For the purpose, a case of a small and medium sized hospital's experience of crisis management during 2015 Middle East Respiratory Syndrome outbreak was analyzed. Methodology/Approach: The detailed internal circumstances and experiences of the hospital during the MERS outbreak were identified by in-depth interview as well as the extensive material review, and analyzed under the view of the theories of accident, error, and crisis in relation of organization management Findings: Overall, nine propositions are drawn by the phase of crisis. In pre-crisis phase, for example, 'the hospital preparedness has positive influence on the effective responding to the crisis'. In detection phase, 'the mindfulness of the hospital organizations' as well as the individuals' has positive influence on detecting the crisis signals'. In crisis phase, for example, 'improvising naturally occurs in crisis by the unknown disease, therefore, a component site supervisor coordinating such improvision is important'. Lastly, in post-crisis phase, 'successful crisis responding experience facilitates the positive hospital culture'. Practical implication: From the experience of a small and medium size hospital, it is suggested that proactive system approach oriented by safety is beneficial for effective crisis management.

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.

고등학생의 노화관련지식이 노인에 대한 태도에 미치는 영향

손희정 ( Hee Jung Son ) 인구교육센터 2009 인구교육 Vol.2 No.1

노인 및 노화에 관한 지식을 가르치는 것이 실제로 가치형성 및 변화에 기여하는지 분석하고, 교육내용으로 구성하는 것의 실제적 유용성에 대해 논의하였다. 노화관련지식 수준의 측정 결과, 노화에 따른 변화에 대해 잘못 이해하고 있는 경우가 많았으며, 잘못된 지식을 가진 경우 긍정적인 고정관념보다 부정적인 고정관념이 우세하였다. 노인의 신체적 특성에 관해 비교적 많은 지식을 갖고 있었으나, 신체적 변화의 이해정도는 노인에 대한 태도에 별다른 영향을 주지 못했다. 그보다는 오히려 심리적 지식과 사회적 지식의 영향이 더 컸다. 심리적,사회적 변화는 연량과의 연동성이 적은 편이며, 이는 부정적 태도의 주된 원인이 연령증가로 인한 필연적 변화에 근거한 것이기 보다 ‘나이가 들면 으례 그렇게 될 것’이라는 그릇된 신념에서 비롯됨을 의미한다. 노화에 따른 심리적,사회적 변화에 대한 이해를 도울 수 있는 교육 내용의 구성이 필요하며, 이를 도울 수 있는 실증적 사례나 토론 주제의 개발이 필요하다. 개발된 자료를 사회,윤리,가정 등 인구교육 관련교과나 재량활동 시간을 통해 교육내용에 반영될 수 있도록 지속적인 지원이 이루어져야 한다.

췌장의 점액생성 낭성종양으로 오인되었던 췌장선암

손희정(Hee Jung Son),이선영(Sun Young Yi),한운섭(Woon Sup Han) 대한소화기학회 1996 대한소화기학회지 Vol.28 No.2

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.
