  • With the effectuation of Kyoto Protocol, one of the important movement throughout the world is reducing the emission of greenhouse gas which is the main reason of making global warming. The actual factor of greenhouse gas is CO2, and in year of 2002 20% of total CO2 emission was produced only through transportation throughout the South Korea. In the contrary, the recycling of municipal wastes in South Korea was 44.0% in 2002, but it will be targeted upto 53.5% in 2011. This study applied survey research for the activities affecting to the emission of CO2 and packaging wastes produced from transportation and packaging stages in logistics area. For this, survey questionary was constructed with five specific areas - strategy, transportation & distribution, custody, packaging, and information. Based on the 144 returned survey questionaries, this study analyzed 54 categories and finally suggests necessary four alternative in Korea.

  • The purpose of this study was to investigate the effects of group music therapy on the emotional stabilisation and Self-Efficacy of juvenile delinquents. The subjects, who were from age 15 to 19 as juvenile delinquents, received juvenile protection Order one (1) and three (3) or Order (4) and were placed in custody designated by the Gwang Ju Family Court. The 24 subjects were divided into the experimental group (N=12), and the control group (N=12) at random. The experimental group was given 14 group music therapy session for 90 minutes each, two times a week, and the control group was not given any. Emotional stabilisation and the Self-Efficacy scores for each adolescent was compared before and after the experiment. Statistical methods used for data analysis were mean, the standard deviation, and the ANCOVA. Results are as follows. The experimental group was significantly increased in emotional stabilisation compared with the control group. The experimental group was significantly decreased in aggressive behavior compared and in stress compared with the control group. The experimental group was significantly increased in self-efficacy compared, in self-confidence compared and in self control efficacy compared with the control group. These results suggest that group music therapy are positive effects on improving the emotional stabilisation and the Self-Efficacy of juvenile delinquents.

  • Coriolis mass flowmeter(CMF), which can measure the mass flow directly, is getting rapid attention for the industrial and custody transfer purpose. In order to study the characteristics and the applicability of CMF, it is tested with the national flow standard system. Two types of sensing tube, U-type and straight type, are employed in the test. Water, spindle oil and viscosity Standard Reference Material whose viscosities are 1, 20 and, 67 $\textrm{mm}^2$/s, respectively, are studied. It is shown that the linearity of CMF is getting deteriorated as the fluid viscosity increases, which is due to the zero drift and the relaxation time of the fluid. To test its applicability in the case of high pressured gas, it is calibrated using compressed air, It shows 1∼l.6 % deviations compared to the calibration results using water. It concludes that the fluid velocity in CMF should be lower than the sonic velocity. In addition, the effects of the vibration from the pipeline and pump on CMF as well as the long term stability are studied.

  • Orifice meter is the most widely used flowmeter in custody transfer between KOGAS and city gas companies. Absolute pressure value is needed to calculate the gas flow of orifice metering system, but the gauge pressure transmitters are mainly used in the field. In case that the gauge pressure transmitters are used, the fixed value as standard atmospheric pressure(101.325kPa) is applied for the absolute pressure value. The real, local atmospheric pressures of each metering station are different from the standard condition as the altitude and weather conditions. In this study the flow calculation errors were quantitatively analyzed through examining the atmospheric pressures of 50 stations of KOGAS. The data for analysis are such like the time data of supplied gas amount, the altitude of each metering station, the time data of atmospheric pressures and altitudes of each weather observatory. The results showed that the local atmospheric pressures were different from the standard value and the gas flow calculation errors were distributed between $-0.024\%{\~}0.025\%$ based on the supplied gas amount in the year 1999 and 2000.

  • 2000년대에 접어들어 컴퓨터가 보급화 되면서, 컴퓨터를 도구로 하는 범죄가 폭발적으로 증가하기 시작하였다. 컴퓨터 시스템에 접근하여 중요 정보를 빼돌리거나, 범죄의 목적이 되는 해킹과 같은 정보보호 침해사고가 크게 증가하였으며, 컴퓨터를 이용한 정상적인 서비스를 방해하는 형태의 디지털 범죄들이 다수 발생하기 시작하였다. 따라서 범죄 수사 과정에서 전자 매체에 대한 분석이 필수 불가결한 요소로 등장하고 있으며, 이를 분석하려는 디지털 포렌식 연구가 활발히 진행되고 있다. 특히 전자 매체에 기록되는 디지털 정보는 보관이 편리하지만 삭제와 복제가 용이하므로 디지털 증거는 매우 세심하게 다루어야 하며, 수사관에 의한 의도적인 훼손이 없었음을 증명할 수 있는 절차와 제도가 필요하다. 국내에서는 적법한 수사 절차와 무결성을 보장하기 위하여 '절차 연속성(chain-of-custody)'을 제공하는 수사 가이드라인을 제작하였으며, 체계적인 수사를 수행 하고 있다.[4] 이와 더불어 포렌식 수사 과정에서 물리적인 접근을 통해 디지털 저장 매체에 대한 복구할 수 있는 방법이 존재하며, 이에 대한 구체적인 방안을 논한다.[1]

  • The Korea now incarcerates a greater percentage of its Population than any other country : For 63,000 prisoners in 40 prisons and jails. Most inmates are mate. young, poor, and morbidity groups. Most are substance abusers with substantial physical and mental health needs. Corrections in general and correctional health care in particular have suffered negative consequence : severe overcrowding, insuffcient programs as the acquired immunodeficiency syndrome(AIDS). tuberculosis, and hepatitis. The large increase in the number of substance abusers and sick and terminally ill inmates has rendered our nation's prisons and jails physically or financially unable to deal with their current populations, much less the explosive increases the future holds. It is the magnitude of inmate health problems that threatens to overwhelm the substantial gains made in correctional health care over the past two decades. As measured by recognized standards of inmate health and health services, our correctional systems are in crisis. As a nation. we must respond to the problem of health problem with national strategies that do not overwhelm the capacity of our criminal justice system to care for its inmates.

  • Fingerprinting is a frontier technique that is the most frequently applied for human identification throughout the world. All citizens over 17 year old living in the Republic of Korea must be fingerprinted to obtain a certificate of resident registration. In Korea, for this reason, human identification through fingerprints has been far better developed and used efficiently both in crime scene investigation and in confirmation of an unidentified body. Scientific approaches have been made to accurately extract the metamorphosed fingerprints in various environments. Because most of the studies on fingerprinting have been accomplished with biometric techniques, researches on restoration of human dermal tissue and taking custody data after collecting fingerprints have been comparatively undermined. In this study, a newly innovative method for fingerprint extraction was developed using the polyester film with print powders and the high temperature-moisturizing method. Compared to the conventional fingerprinting method of paper with ink, minutiae numbers of fingerprints were greatly increased in polyester film with print powders after restoration of fingertips by high temperature-moisturization. This newly developed procedure would be an efficient fingerprinting technique which could be utilized in scientific investigation and in personal identification in the future. Furthermore, the new method for restoration and extraction of fingerprints are easy and inexpensive to practice for a number of human identification.

  • By measuring concrete temperature and strains of concrete and reinforcing bars throughout gages embedded and also by observing the crack occurrence, this study aims at the characteristics of structural behavior of subway wall structure in associate with concrete ages. The length of 23.5m, thickness of 2.0m of real subway custody line was selected as a representative structure and 7 thermocouples and 6 strain gages were installed to measure the behavior of wall structure. The results were compared and verified with analytical results using MIDAS in order to show their usefulness. It was found that only attachment of strain gages on the surface of reinforcing bars can figure out the timing of crack occurrence and hydration heat program is useful to estimate comparatively exact magnitudes of temperature. Since estimated time of crack occurrence throughout thermal stress analysis depends on the period of transferred thermal stress from concrete to reinforcing bars, however, cracks from naked eyes were identified later than analytical results. Cracks were observed first at the center of wall line and then to the end of line symmetrically.
