일반아나 학습 부진아를 대상으로 진행된 많은 선행 연구에서 출생월에 따른 학교입학연령이 아동의 학업성취에 중요한 영향을 미치는 것으로 밝혀 왔으며, 우리나라 영재아를 대상으로 진행된 본 연구에서도 이러한 양상은 그대로 적용되는 것으로 나타났다. 과학영재교육원 초 중등 영재선발 과정에 응시한, 그리고 영재로 선발된 아동의 구성원이 학교입학연령에 따라 어떠한 양상을 나타내는지 알아본 결과, 2006, 2007학년도 영재선발 응시자 및 합격자 그룹 모두 각 학년에서 나이가 가장 많은 봄 출생아의 수가 월등히 많은 것으로 나타났다. 또한 이러한 초등학교 입학연령은 초등학교뿐만 아니라 중학교 단계에까지 아동의 학업성취에 영향을 미친다는 점이 밝혀졌다. 이러한 연구 결과들을 바탕으로 학교입학연령에 따른 아동의 학업성취의 차는 이들의 성숙의 차를 의미할 수 있다는 결론을 내리게 되며 또다른 아동에 비해 일찍 학교를 입학한 상당수의 아동이 학업성취에 있어서 열세하다는 시사점도 얻게 된다. 이 외에도 이러한 요인이 일반아와 부진아뿐만 아니라 영재선발에까지도 중요한 변인으로 작용한다는 결론은 우리가 주의 깊게 고려해 보아야 할 부분일 것이다.

This study was conducted to find qualitative approaches to occupational reference to group health practices. In-depth interviewing was done on 8 subjects health monitor members, owners and occupational nurses, respectively). The major findings were as follows; 1. Visiting health management Useful services were 'health counseling', 'medical examination', 'providing informations about managing diseases', 'agency business in relation to Labour Ministry' and 'giving a recognition about occupational health service to owners'. Insufficiencies were 'lack of treatment service after medical examination' and 'lack of follow up services constantly'. 2. Occupational nursing service Useful services were 'providing health information' and 'counselling about health'. Major contents of occupational nursing services were 'management of occupational and adult diseases' and 'explanation of the results after medical examination'. Insufficiencies were 'deficiency of the place where group health education could be performed', 'lack of additional or closer examinations needed in counselling' and 'discontinuous selection of additional or more exact examinations'. 3. Health monitor members Health monitor members in industries were classified into two. Some were selected by owners and the others were selected simply by considering their administrative abilities such as proficient management of documents. Their major tasks were to connect workers with occupational health management agencies. This study suggests that programs should be developed which enable health monitor members to cooperate with occupational nurses.

The major cause of Concrete Spalling at high temperatures can be divided into the Vapor Pressure Rising, caused by the increase in free water temperature within the concrete, and Pore Pressure Rising induced by the vapor moving into dense pores within the concrete. Although the occurrence of spalling within concrete caused by these pressure increases can be assessed experimentally, a close examination into Mechanistic influence against various spalling factors shall be carried out first by using Mathematical Modeling and Theoretical Equations. The Spalling Prospect Process by theoretical mechanism is expedited in order of the following; selection of heating condition (fire strength and flame heating direction), a selection of constituent elements, an analysis of heat transmission, an analysis of moisture movement, distribution of water content, an analysis of pore/vapor pressure, and assessment of spalling occurrence.

This paper addresses a problem of machining determination of input quantity in a multi-stage flexible flow system with non-identical parallel machines considers a subcontracting, machining restraint, and machine yield. We develop a nonlinear programing with the objective of minimizing the sum of in-house processing cost and subcontracting cost. To solve this model, we introduce a single-processor parallel genetic algorithm(SPGA) to improve a weak point for the declined robustness of simple algorithm(SGA). The efficiency of the SPGA is examined in comparison with the SGA for the same problem. In of examination the SPGA is to provide the excellent solution than the solution of the SGA.

To identify and evaluate the risk factors in WMSD work, a number of ergonomic workload evaluation methods have been developed. In the legal examination of WMSD risk factors, simple observational workload evaluation methods are widely used instead of using costly measurement equipments such as EMG and motion analyzer. The simple workload evaluation methods can be categorized into three groups; risk factor checklist methods, posture observation methods, and manual material handling task evaluation methods. In terms of the categories, this survey summarized several representative workload evaluation methods and compared them each other. Then some industrial application cases referring each the workload evaluation methods were surveyed. Due to the characteristics of each method, the selection and application procedure of workload evaluation method should be appropriate for the corresponding work. Therefore, some guidelines for the selection and application procedure of workload evaluation method were suggested.

The safety and effectiveness of colonoscopy in the investigation of lower gastrointestinal tract pathology in children has been established for more than 2 decades in Korea. The skill and experience have since advanced to the point that both diagnostic and therapeutic colonoscopy are now routinely performed by most pediatric gastroenterologists. Pediatric colonoscopy differs significantly from its adult parallels in nearly every aspect including patient and parent management and preparation, selection criteria for sedation and general anesthetic, bowel preparation, expected diagnoses, instrument selection, imperative for terminal ileal intubation, and requirement for biopsies from macroscopically normal mucosa. Investigation of inflammatory bowel disease, whether for diagnosis or follow-up evaluation, and suspected colonic polyps are the most common indication for pediatric colonoscopy. The child who presents with signs and symptoms of lower gastrointestinal disorder should undergo colonoscopy with biopsy to make the diagnosis, as well as to help determine the appropriate therapy. This review introduces practical information on pediatric colonoscopy, the author's experiences, and the role of colonoscopic examination in the diagnosis and treatment of pediatric lower gastrointestinal disorders.
