Seongho Ki,Namkwun Park 한국재난정보학회 2014 한국재난정보학회 논문집 Vol.10 No.4

최근 노량진 수몰사고, 방화대교 붕괴사고 등의 대규모 건설재해가 끊이지 않고 발생하고있다. 이에 건설공사 현장에서 재해 저감을 위한 다양한 공사참여자의 역할 및 책임이 중요한 요소로 인식되고 있는 실정이다. 건설 산업은 계획, 설계, 시공, 유지관리 단계를 거치면서 발주자를 비롯한 설계자, 시공자 등 다수의 행위주체들이 참여하여 공사목적물을 만들어 가는 일련의 과정이다. 그러나 현행 안전관리의 주체는 근로자를 직접 고용하는 원도급자인 시공사에게만 책임이 집중되고 최상위에서 의사결정 권한을 행사하는 발주자의 안전활동 참여는 배제되고 있다. 이에 본 연구는 각 공사참여자를 대상으로 안전활동에 대한인식수준 및 실태에 대하여 파악하고, 이를 통해 발주자 중심의 안전관리체계에 대한 개선방안을 제시하였다. Large scale construction disasters such as recent Noryangjin flooding incident andBanghwadaegyo collapse accident are occurring persistently. Thereupon, the role andresponsibility of the various construction participants are considered as major element toreduce disaster at the construction site. Construction industry is a process of buildingconstruction object by going through planning, designing, constructing, and maintenancecontrolling in which various bodies of act, from contractor to designer and builders,participate. However, the subject of current safety supervision is focused on the builder,the contract enterprise which directly employs workers, while the safety activityparticipation of the contractor, who exerts decision-making authority at the highest level,is excluded. Therefore, this study understands the level of awareness and reality on thesafety activity of each construction participants from which the improvement plan on thecontractor centered safety management system is proposed.

The reliable information on the hydraulic characteristics of rock mass is one of the key site factors for design and construction of deep subsurface structures such as geological radioactive nuclear waste disposal repository, underground energy storage facility, underground research laboratory, etc. In order to avoid relying on foreign field test technology in future projects, we have independently designed and made integrated type main frame, 120 bar waterproof downhole sonde, and 1,200 m wireline cable winch through a series of R&D activities. They are core apparatuses of the Deep borehole Hydraulic Test System (DHTS). Integration of individual test equipment into a single main frame allows safe and efficient work in the harsh field condition. The DHTS was developed aiming primarily for constant pressure (head) injection test and pulse test in deep impermeable rock mass. The maximum testing depth of the DHTS is about 1,050 m from the surface. Using this system, it is possible to make precise stepwise control of downhole net injection pressure in less than 2.0 kgf/cm2 with dual hydraulic volume controller and also to inject and measure the very low flow rate below 0.01 l/min with micro flow rate injection/control module. Over the past two years, we have successfully completed more than 50 in situ hydraulic tests at 5 deep boreholes located in the Mesozoic granite and sedimentary rock regions in Korea. Among them, the deepest testing depth was more than 920 m. In this paper, the major characteristics of the DHTS are introduced and also some results obtained from the high precision field tests in the deep and low permeable rock mass environment are briefly discussed.

Adipose-Derived Stromal Vascular Fraction Cells: Update on Clinical Utility and Efficacy

Han, Seongho,Sun, Hyun Min,Hwang, Ki-Chul,Kim, Sung-Whan Begell House Inc. 2015 Critical reviews in eukaryotic gene expression Vol.25 No.2

<P>Adipose tissue has emerged as an attractive cell source in tissue engineering and regenerative medicine because it can be easily collected and enriched with stem/progenitor cell populations. The stromal vascular fraction (SVF) derived from adipose tissue contains heterogeneous cell populations such as mesenchymal progenitor/stem cells, preadipocytes, endothelial cells, pericytes, T cells, and M2 macrophages. SVF-derived mesenchymal progenitor/stem cells can be easily expanded in vitro and have the potential to create diverse lineages of cells. Although there have been issues related to their isolation and purification, SVF cells demonstrate regenerative potential in damaged tissues or organs through paracrine and differentiation mechanisms. Furthermore, SVF cells augment immunological tolerance by promoting inhibitory macrophages and T regulatory cells and by decreasing ongoing inflammation. Numerous implantations of freshly isolated, autologous adipose tissue-derived SVF cells in cosmetic surgeries and in a wide variety of other specialties support the safety of SVF cells and have accelerated their clinical application. Despite these attractive advantages of SVF cells in clinical interventions, to our knowledge the recent status of clinical studies of various diseases has not been fully investigated. Therefore this article describes recent advances in the clinical use of SVF cells, as well as the associated challenges and future directions for this field of research. We also speculate that verification of the efficacy and safety of SVF cells requires more basic experimental research, using a standard isolation protocol, and larger randomized clinical trials of the utility of SVF cells in various diseases.</P>

목 적 : 본 연구의 목적은 보상만족도가 재해 후 정신병리와, 삶의 질의 변화에 미치는 영향을 알아보는 것이다. 방 법 : 강원도 인제군 가리산리는 농작업 안전관리현황 진단을 위한 코호트로 선정되어, 2006년 4월부터 수해가 일어나기 직전인 7월까지 주민 83명의 신체적 및 정신적 건강실태에 대한 기초조사가 이루어졌다. 저자들은 수해 후 18개월에 1차 조사, 24개월에 2차 조사를 시행하여, 한국판 36-단축형 건강조사(36-Item Short-Form Health Survey-Korean version, SF-36)를 사용하여 삶의 질을 측정하였고, 단축형 사회심리적 스트레스(Psychological Well-being Index Short form, PWI-SF), 개정판 사건충격척도(Impact of Event Scale-Revised, IES-R), Beck 우울척도(Beck Depression Inventory, BDI) 등을 사용하여 정신병리를 측정하였으며, 보상에 대한 만족도에 대해 조사하였다. 결 과 : 55명 중 보상만족도가 보통 이상은 12명(21.8%), 불만족은 33명(78.2%)이었으며, 두 집단간의 인구사회학적 특징은 차이가 없었다. 보상만족도에 따라 시간에 따른 BDI, IES-R, AUDIT 점수의 변화에는 차이가 없었다. SF-36은 보상만족도가 높은 집단에서 수해 후 18개월에 감소하였다가 24개월 증가하였으며, 보상만족도가 낮은 집단은 수해 후 18개월에 증가하였다가 24개월에 감소하 였다. 결 론 : 수해는 피해자들의 정신건강에 장기간 영향을 미치며 보상만족도는 수해 후 삶의 질 변화에 영향을 미친다. Objectives : This study aims to examine the effects of compensation satisfaction on psychopathology and quality of life following flood. Methods : Garisan-ri of Inje-gun, Gangwon-do was chosen as a cohort regarding evaluating of agricultural safety management status. A baseline survey had been administered just before the flood. A follow-up study was conducted for 24 months. Psychopathology and quality of life were assessed using BDI, IES-R, SF-36 and PWI-SF. Satisfaction with the flood compensation was also evaluated. Results : There was a total of 55 respondents. There was no significant difference between the low satisfaction group (N=43, 78.2%) and middle & high group (N`12, 21.8%) in the sociodemographic factors. There were no significant differences in changes in BDI, IES-R, and AUDIT score over time between the two groups. While SF-36 in the low satisfaction group was increased at 18months after the disaster and decreased at 24months, SF-36 in the middle and high satisfaction group decreased at 18 months after the disaster and increased at 24 months. Conclusion : The flood disaster had a long-term effect on the flood victims’ mental health. Satisfaction with compensation affects changes of quality of life following a flood disaster.

Shin, Sunhee,Yeon, Seongho,Park, Dongsun,Oh, Jiyoung,Kang, Hyomin,Kim, Sunghyun,Joo, Seong Soo,Lim, Woo-Taek,Lee, Jeong-Yong,Choi, Kyung-Chul,Kim, Ki Yon,Kim, Seung Up,Kim, Jong-Choon,Kim, Yun-Bae Pharmaceutical Society of Japan 2010 Biological & pharmaceutical bulletin Vol.33 No.2

<P>The effects of a silk amino acid (SAA) preparation on the physical stamina and male reproductive function of mice were investigated. Eight-week-old male ICR mice (29—31 g) were orally administered SAA (50, 160 or 500 mg/kg) for 44 d during 30-min daily swimming exercise. The mice were subjected to a weight-loaded (5% of body weight) forced swimming on the 14th, 28th and 42nd day to determine maximum swimming time, and after a 2-d recovery period (treated with SAA without swimming exercise), parameters related to fatigue and reproductive function were analyzed from blood, muscles and reproductive organs. Repeated swimming exercise increased the maximum swimming time to some extent, in spite of a marked reduction in body weight gain, and SAA further enhanced the stamina in a dose-dependent manner. Forced swimming exercises increased blood parameters of tissue injury, but depleted blood glucose and tissue glycogen, which were substantially prevented by SAA treatment. In addition, SAA significantly reduced the muscular thiobarbituric acid-reactive substances and blood corticosterone content increased by forced swimming. Swimming exercise decreased the blood testosterone level, which was recovered by SAA, leading to enhanced sperm counts. These combined results indicate that SAA not only enhances physical stamina by minimizing damage to tissues, including muscles, as well as preventing energy depletion caused by swimming stress, but also improves male reproductive function by increasing testosterone and sperm counts.</P>

Objective : This study explored a conceptual model for predicting psychopathology in Korean children of alcoholics by using path analysis. Methods : Data were collected from 502 male adolescents from two middle schools in urban areas. Each participant completed the questionnaire which included demo-graphic data, Children of Alcoholics Screening Test (CAST-K), Child’s Attitude Toward Parents (CATP), General Self-Efficacy Scale (SES), and Strengths-Difficulties Questionnaire Self-Report (SDQ-SR). Results : 57 (11.4%) participants were children of alcoholic parents (A ; CAST-K≥13), 94 (18.7%) participants were children of problematic parents (P ; 7≤CAST-K<13), and 351 (70%) participants were children of normal parents (N ;CAST-K≤6). The children of alcoholics (A) scored lower on CATP (N > P,A ; p<0.001) and SES (N > A ; p<0.01), and high-er on hyperactivity (N<P,A ; p<0.001), emotional symptoms (N, P<A ; p<0.01), conduct problems (N<A ; p<0.01), peer difficulties (N<A ; p<0.01), and total difficulties (N<P<A ; p< 0.001). In path analysis, parental alcohol use had a significant effect on total difficulties directly (β=0.16, p<0.001) and indi-rectly mediated by CATP and SES, with a R 2 of 0.28. Also, pa-rental alcohol use had an indirect effect on early alcohol use in adolescents mediated by total difficulties. Conclusion : Parental problematic drinking may increase the likelihood of psychopathology and alcohol use in male offsprings in their early adolescence directly and indirectly.

Objectives : The aim of this study is to investigate the relationships between chronotype and alcohol use in young adult. Methods : A total of 197 medical students (age range : 18-25 years, female : 34.5%) participated in this study voluntarily. Each participant completed a self-administered questionnaire that included demographics, plus the Morningness-Eveningness Questionnaire (MEQ), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Barratt Impulsiveness Scale (BIS), Pittsburgh Sleep Quality Index (PSQI), and Alcohol Use Disor-ders Identification Test (AUDIT). Results : Sixty-one (30.96%) were problem drinkers, with men making up a higher percent-age of problem drinkers (p<0.001). PD obtained a higher total score on the MEQ (p<0.01). Evening types reported significant-ly greater levels of problem drinking and worse sleep quality (p <0.05). Multiple regression analysis revealed that MEQ was correlated with AUDIT after controlling for sex, age, BDI, STAI, BIS, and PSQI (p<0.001). Conclusion : Our findings suggest a direct association between problem drinking and eveningness.

Objectives:Previous studies reported that patients with alcohol dependence had low self-esteem, which affect interpersonal relationship. The purpose of this study was to investigate the col-lectivistic and sociotropic tendencies of male patients with alcohol dependence (AD) and it’s relations to self-esteem. Method:The subjects, all male in gender, were 91 patients who met DSM-IV criteria for AD and 97 normal controls. We administered a questionnaire for demographic data, Rosenberg Self-Esteem Scale (SES), Personal Style Inventory-II (PSI-II) for sociotropy-au-tonomy and Individualism-Collectivism (INDCOL). Results: AD patients were lower in education level and more in unmarried status than normal control group (p<0.001, p=0.002, respectively). Self-esteem score was lower in AD patients than in normal controls (t=-9.484, p<0.001). Scores of sociotropy and auton-omy subscale of PSI-II were higher in AD patients (t=3.454;p<0.001, t=3.454;p=0.001, respectively). Self-esteem of AD patients had negative correlations with sociotropy (r=-0.229, p<0.01) and autonomy (r=-0.294, p<0.01) of PSI-II. There was no significant difference in the INDCOL score between two groups. Conclusion:Our study findings show a mixed presentation of heightened sociotropy and autonomy of AD patients. From these findings we suggest that patients with AD may overly in-vest in interpersonal relations as a source of their self-esteem on one hand, and in maintaining a sense of separatedness and independence from others on the other hand.
