In sample surveys, we expect preferred samples that reduce the survey cost and increase the precision of estimators will be selected. Goodman and Kish (1950) introduced controlled selection as a method of sample selection that increases the probability of drawing preferred samples, while decreases the probability of drawing nonpreferred samples. In this paper, we obtain the controlled plans using the maximum entropy principle, and when the order of nonpreferred samples is considered, we propose the algorithm to obtain a controlled plan.

The reinforcing steel process is composed of the development of placing drawing, cutting and bending, and the placement and fabrication of the reinforcement, and is participated in by reinforcement detailer, the fabricator and placer. Because the reinforcing steel process-from estimating and rebar detailing, to production, material tracking, billing, and general accounting-is conducted by many participant, reinforcement details based on building code and reinforcing bar detailing standards are essential. The process, however, holds some problems. Building code has been revised recently, and the utilization of placing drawings was proved to be low, and the reinforcement estimating in early stage of the process is below what is required for placement. Therefore, in this study, a survey was conducted to the reinforcement detailer, the fabricator and placer of domestic construction industry. According to the analysis of the survey, the reinforcement details on site was not standardized. The improvement in reinforcing steel detailing standards was sought by analyzing the results of the survey including reinforcement constructability.

현재 수치지도를 비롯한 모든 공간정보의 속성정보를 취득하기 위한 방법으로는 현장에서 직접적인 조사를 수행하는 지리조사가 일반적이다. 그러나 수치지도 제작을 위한 지리조사는 수치지도에서 표현하는 모든 지형지물에 대한 현장 직접조사를 수행하여야 하기 때문에 지리조사의 범위가 매우 광범위하다. 또한 현재의 지리조사는 지리조사원도(종이지도)를 이용하여 수작업에 의한 조사방법을 이용하기 때문에 조사에 많은 인력, 경비, 시간이 소요되고 있다. 최근 일부 지리조사를 휴대용 및 차량용 MMS(Mobile Mapping System)를 이용하여 전산화 정보를 수집하고 있으나, 직접적으로 수치지도의 제작에 이용하기 위해서는 해결해야 할 문제점들이 있다. 본 연구에서는 현행 지리조사 기준 및 방법의 문제점을 분석하고 국내 외 공간정보 구축 및 서비스 기관의 지리조사 방법을 조사하여 수치지도 제작에 적합한 지리조사 기준 및 방법을 제시함으로써 수치지도 제작 업무의 효율성을 높이고 수치지도의 최신성 및 신뢰도 향상과 지리조사 자료의 활용성을 증대시켜 전국기반 수치지도의 활용성을 극대화 하고자 한다.

The purpose of this study is to understand the transition process of Korean architecture and urbanism from traditional state to modern state, by investigating the development of modern survey and the characteristics of survey drawings during the Great Han Empire (大韓帝國), the early modern Korea. The governmental efforts of the Great Han Empire to introduce a modern survey system named Gwangmu Land survey (光武量田事業) ended in failure. After the Russo-Japanese War (露日戰爭, 1904-1905), the Residency-General (統監府) held the hegemony of Korean Peninsula. It reintroduced a modern survey system for the survey of land and buildings all over the country and enforced the Land and Buildings Certification System (土地家屋證明制度). Since then, the land and buildings survey was propagated rapidly and the modern system for land use was gradually organized. With the progress of modern survey, the survey bureau of Cabinet (內閣) and Department of Royal Household (宮內府) created survey drawings that had some characteristics of colonialism. Takjibu (度支部) produced cadastral maps of major cities, with which the modern land system was developed. In addition, the Royal Property Bureau (帝室財産整理局) produced survey drawings of land and buildings owned by the Royal Household which were finally converted into modern facilities.

Purpose: Somatotype drawing developed by Sorensen et al.(1983) has been evaluated as a simple instrument of obesity level without real somatic measuring as height and weight. This study was designed to validate somatotype drawings for obesity assessment by bioelectrical impedance body component analysis. Method: At first questionnaire of somatotype drawing was done. Subjects were measured body component by bioelectrical impedance analysis as weight, BMI(body mass index), WHR(waist-hip ratio), body water, protein mass, mineral mass, body fat mass, skeletal muscle mass, soft lean mass, fat free mass and percent body fat. We evaluated correlations between these data and somatotype drawings and tried to grouping of somatotype drawings with the means of major body component value. Result: The data were collected from 205 college women whose height and weight were $161.2\pm4.8,\;55\pm8.3$. Spearman's correlation coefficients of somatotype drawing were 0.74 with BMI, 0.68 with weight 0.69 with body fat mass, 0.65 with WHR. 0.64 with percent body fat after adiusted age. The grade of somatotype drawings were grouped as 1-2, 3-4, 5-6. 7-9 by BMI, body fat mass, weight, 1, 2-4, 5-6, 7-9 by WHR and 1-2, 3-4, 5-9 by percent body fat(ANOVA and Duncan's method). Conclusion: So quick instrument using somatotype drawings were useful tools for evaluation of obesity level and is applicable to screen degree of body fat in self-administered questionnaire survey.

Fishery sea anchor is widely used for many fishing vessels. However, standardization of the dimension and terminology of the fishery sea anchor has not been achieved, reducing the reliability of the performance and safety of the fishery sea anchor. Therefore, this study researches the reality of usage of fishery sea anchor and then attempts to suggest the development direction of the standard draft as basic data. As a result of the survey on the reality of usage show that various terms were used for each part of the fishery sea anchor (including the incorrect form of non-standard words derived from Japanese) and that the production of this product in the fishery sea anchor market was concentrated on one specific manufacturer. In addition, the main specifications of the fishery sea anchor are set and manufactured based on conventional experience without standards. In the field, there was no standardized drawing for fishery sea anchor and users had low awareness of the main specifications of fishery sea anchor. Therefore, this study suggested the following regarding the fishery sea anchor: standard terms for each part including Korean and English names and standard drawing of sea anchor. It is hoped that this study will contribute to research for the standardization of fishery sea anchor, which will increase in reliability and lead to increased interest in standardization in the fishery field.
