This paper presents the safety performance of Korean domestic construction companies including the characteristic and current status of safety management actions of the firms. Safety performance both at the head office and job sites of each construction companies, which are divided four groups by construction capacity ranking, are investigated. General recognition that there is a wide difference of safety performance among domestic construction companies by construction capacity ranking was confirmed by comparing the safety performance at the head office and the job sites of the companies under the study. Data analysis shows that the safety performance of the group I and II has the largest difference, and this difference of the group II and III and group III and IV are gradually decreased, respectively. This paper presents the safety performance improvement measures, which is applicable to safety management components consisting of both the head office and job sites safety management systems of each group (e.g., I, II, III and IV) suffering the lack of safety performance.

The objective of this study was to investigate urinary cut-off concentrations of quetiapine and risperidone for distinction between normal and abnormal/non-takers who were being placed on probation. Liquid chromatography-tandem mass spectrometric (LC-MS/MS) method was employed for determination of antipsychotic drugs in urine from mentally disordered probationers. The optimal cut-off values of antipsychotic drugs were calculated using receiver operating characteristic (ROC) curve analysis. The sensitivity and specificity of the method for the detection of antipsychotic drugs in urine were subsequently evaluated. The area under the ROC curve (AUC) was 0.927 for norquetiapine and 0.791 for 9-hydroxyrisperidone, respectively. These antipsychotic drugs are classified readily in the ROC curve analysis. The cut-off values for distinguishing regular and irregular/non-takers were 39.1 ng/mL for norquetiapine and 67.9 ng/mL for 9-hydroxyrisperidone, respectively. The results of this study suggest the cut-off values of quetiapine and risperidone were highly useful to distinguish regular takers from irregular/non-takers.

A prototypical building that represents the energy characteristics of buildings can be used as a mean of improving building energy efficiency by supporting policy makers, researchers, architects and engineers. This paper is a fundamental study for the definition of prototypical office building models of Korea. First of all, the term "prototypical buildings" was defined in the context of the representatives of building stock by examining the meanings used from many previous researches. Then, building energy related DB of Korea that is available from public and governmental organization such as MLIT (Ministry of Land, Infrastructure and Transport) and KEEI (Korea Energy Economics Institute) is analyzed in terms of materials for prototypical building definition. Finally, numerous prototypical building studies since 1990's from all of the world were classified with three criteria based on the degrees of the used DB and assumptions in defining prototypical building. The found three criteria are EDPB (Empirical Decision based Prototypical Building), HIPB (Hybrid Information based Prototypical Building) SAPB (Statistical Analysis based Prototypical Building).

최동훈은 국내에서 학문적으로 활발하게 다뤄지지 않는 경향이 있다. 하지만 그의 작품들이 어떤 이유로 흥행에 성공하고 시장에서 살아남는가라는 관점에서 본다면 새롭게 다뤄볼 여지가 있어 보인다. 여기서는 최동훈의 오리지널 시나리오이면서 케이퍼필름 장르에 속하는 두 천만 관객 영화 <도둑들>과 <암살>을 분석 대상으로 삼아, "잘 짜여진 이야기"의 측면에서 그 성공 요인을 살펴보고자 한다. 흔히 웰메이드 영화는 장르 관습적인 면과 독창적인 면 모두를 갖추고 있다. 최동훈의 영화 역시 마찬가지다. <도둑들>과 <암살>은 케이퍼필름 장르 관습을 충실히 따른다. 동시에 이 두 영화는 여러 명의 캐릭터가 각자의 이야기 패턴을 가지고 창발적으로 작용하면서 자기조직화하는 복잡적응계적인 독창성도 있다. 그리고 <도둑들>과 <암살>에서는 관습적인 면과 독창적인 면이 적절하게 공존하기 때문에, 이 두 영화는 시장적응력이 가장 높은 상태인 혼돈의 가장자리에 있는 것으로 보인다.

Accurate vital statistics are essential for a national health planning and evaluation. Among various vital statistics, birth and death rates, and infant and matemal mortality rates together with the causes of death are the very basic ones for above purposes as well as for the maternal and child health management. These statistics are based on the birth and death reports. It is required by law to report every birth and death within one month after its occurrence. However, in case of a neonatal death occurring prior to the birth report, most of the birth and death are not reported. Thus accurate infant and maternal mortality rates are not available yet in Korea. The main objective of this study is to develop a birth and infant death reporting system via computer network. We designed a new birth report form based on the current form and data from the analysis of medical record forms of 14 hospitals. A new form is basically addition of essential medical information to the current birth report form. Since a revision of the rules and regulations related wtih the birth report is necessary to use a new form, we kept the current from intact to make it acceptable to the government office for a field trial. We also developed computer programs for data input for birth and death reports at a medical faciltiy, data processing for production of maternal and child health indices at a health center, and management of maternal and child health services including immunization and postantal care at health center. The birth certificate and birth report can be printed out at a medical facility. The computer packages were programmed by Borland Delphi 3.0 and can be run under Windows 95 system. We proposed a new birth and death reporting system via computer network after a field trial for data input, transmission, and processing. The medical and demographic data o birth and death at medical facilities will be sent to health centers directly via computer network. The health center will retain the medical data for analysis and forward only the data for birth and death reports required by current regulations to the Dong, Up, or Myun Office. Once the birth or death is reported via computer network to the Dong Office, then the Dong Office will notify the baby's mother of the birth report and request to submit the baby's name by mail. When the baby's name its submitted. the Dong Office will forward the birth reports to the Common Court and Statistics Agency in the same way as the current system, Upon the completion of birth registration of the Common Court, the court will issue the birth certificate to mother which will be used in lieu of the family record. The advantages of proposed birth and death reporting system via computer network ar as follows ; I) The accuracy, timing, and completeness of reporting will be improved and more accurate maternal and child health indices can be obtained, ii) The maternal and child health services of health center will be obtained, iii) Epidemiologic data for pregnancy and birth can be obtained, iv) Manpower for birth and death reporting will be saved.

In order to present basic data for the balancing improvement of safety management level in domestic construction companies the improvement index and characteristic of safety management level are offered by comparing the year 2006's safety level with the year 2001's one. The companies under concern are classified into 51 large scale companies and 61 middle and small scale ones. The safety management level of both head office and construction sites is improved for all companies without regard to the scale. Specially, the improvement index of middle and small scale companies shows the higher rate than large ones and head office higher than construction sites.

In order to find an environment-friendly method to suppress astragal stem rot caused by the isolates of Rhizoctonia solani AG 1 and AG 4, we tested an antagonistic fungus Gliocladium virens G1 was evaluated as a biocontrol agent and estimated inorganic compounds and organic materials were tested for their effect of the disease suppression. G. virens G1 effectively inhibited mycelial growth in a dual culture and caused mycelial lysis in the culture filtrate. No adverse effect was observed when examined for seed germination and seedling growth. Promoted seedling growth was observed with the seed treatment. Seeds of astragal plant were germinated higher in the sterile soil than the natural soil. Of 14 inorganics tested, alum, aluminum sulfate and calcium oxide significantly suppressed the mycelial growth and sclerotial germination. Milled pine bark and oak sawdust also suppressed the mycelial growth. Soil amended with 1% of G. virens G1 composted with pine bark (w/v) significantly controlled astragal stem rot in the glasshouse experiments.
