본 연구에서는 대학부설 과학영재교육원 소속의 중학생 과학영재 110명을 대상으로 사고 양식, 자기조절학습능력, 과학탐구능력의 특징과 수준을 조사하고, 각 하위 변인들의 관계 및 자기조절학습능력과 과학탐구능력에 유의미한 설명력을 가지는 사고양식은 무엇인지 탐색하고자 하였다. '사고양식'은 Sternberg가 정신자치제 이론에 기초하여 제안한 개념으로 기능, 형식, 수준, 범위, 경향성 등 다섯 가지 차원에서 13가지의 유형으로 구성된다. 사고 양식 검사는 Sternberg와 Wanger (1991)의 TSI를 국내에서 타당화한 검사지를 사용하였고, 자기조절학습능력은 '학습방법검사'로 명명한 자기조절학습능력 검사지를, 과학탐구능력은 국내에서 최근 개발된 과학탐구능력 검사지(TSIS)를 이용하여 측정하였다. 연구 결과, 연구 대상 과학영재들은 입법적 사고양식이 가장 높게 나타났으며 그 외 자유주의적, 외부지향적, 계급제, 사법적 사고양식이 우세하였고 보수주의적 사고양식이 가장 낮게 나타났다. 또한, 이들 사고양식은 자기조절학습능력 및 과학탐구능력과 유의한 상관을 나타내었다. 자기조절학습능력을 유의미하게 설명하고 있는 변인은 입법적, 계급제, 지엽적, 자유주의적 사고양식으로 나타났다. 과학탐구능력에 대한 설명력이 큰 변인은 입법적 사고양식인 반면 과두제 사고양식은 부적으로 나타났다. 한편, 군집분석을 통해 사고양식 유형 및 수준별로 집단을 구분한 뒤, 다변량분산분석을 실시한 결과 사고양식의 유형별 집단에 따라 자기조절학습능력과 과학탐구능력에 유의미한 차이가 나타났다.

The purpose of this study was to identify factors of intrinsic motivation that affect regular breast cancer screening and contribute to development of a program for strategies to improve effective breast cancer screening. Subjects were residing in South Korea Gangwon-Province and were female over 40 and under 69 years of age. For the investigation, the Intrinsic Motivation Inventory (IMI) was modified to the situation of cancer screening and was used to survey 905 inhabitants. Multinominal logistic regression analyses were conducted for regular breast cancer screening (RS), one-time breast cancer screening (OS) and non-breast cancer screening (NS). For statistical analysis, IBM SPSS 20.0 was utilized. The determinant factors between RS and NS were "perceived effort and choice" and "stress and strain" - internal motivations related to regular breast cancer screening. Also, determinant factors between RS and OS are "age" and "perceived effort and choice" for internal motivation related to cancer screening. To increase regular screening, strategies that address individual perceived effort and choice are recommended.

The subjects were 574 eleven-and fourteen-year-olds enrolled in elementary and junior high school in seoul. To measure subjects' depression and attributional style the childrdn's Depression Inventory(CDI) and the Childrens' Attributional Style Questionnaire(CASQ) were used. Adolescents' depression score was higher than that of children's There was no sex difference in Children's and adolescents' depression. In the children's and adolescents' depression there was significant difference according to maternal educational level. That is the lower maternal educational level, the higher children's and adolescents' depression score. As predicted by the reformulated learned helplessness theory Children and adolescents with high levels of depression score were more likely to attribute bad events to internal stable global causes and good events to external unstable specific causes. Subject who were moore depressed had significantly lower academic achievement scores than subject who were less depressed.

We study the firm's strategy to price its products and plan the spare parts manufacturing so as to maximize its profit and at the same time to fulfill its commitment to providing the customers with the key parts continuously over the relevant decision time horizon, i.e., the production plus warrantee period. To examine the research question, we developed and solved a two-stage optimal control theory model. Our analysis suggests that if the cost to produce the spare part during the warrantee period is more expensive than that during the production period, the firm should increase its sales price gradually throughout the production period to control its sales. In addition, during the production period it is optimal for the firm to produce the spare parts more than needed so that the overproduced spare parts can be used to partially meet the demand during the warrantee period. We conducted numerical analysis to investigate the sensitivity dynamics among key variables and parameters such as inventory holding cost, unit spare part production costs, part failure rate, and parameters in the demand function.

The drum-buffer-rope(DBR) system is a finite scheduling mechanism that balances the flow of the production system. DBR controls the flow of materials through the plant in order to produce products in accordance with market demand, with a minimum of manufacturing lead time, inventory, and operating expenses. This paper integrates the best of MRP push system and JIT pull system with DBR system, efficiently adapts these logics to capacity constraint resources, and contributes to the evolution of synchronous manufacturing. The purpose of this paper is, thus, threefold. The first objective is to identify the frame of theory of constraints(TOC) and the logic of DBR scheduling. The second objective is to formulate the DBR constraint scheduling problems(DBRCSP) in a job shop environments. Finally, the paper is to suggest the solution procedure of DBRCSP for embedding TOC into MRP/JIT along with an numerical expression. In addition, illustrative numerical example is given.

Fleet sizing and distribution of empty equipments are two of the most critical problems in managing transportation system. This paper develops a cost model for sizing a fleet and establishing decentralized redistribution polices of empty equipments by building from inventory theory of multi-echelon system in hub-and-spoke network. An analytical approach to determine control variables of redistribution policies in each terminal and fleet size of the transportation system is proposed and its results are validated by simulation model. Numerical experiments are conducted with respect to parameters of the model and test results for assumptions of the model are discussed.

Human blood is a perishable product : it has a legal lifetime of 21 days from collection, during which it can be used for transfusion to a Patient of the same type, and after which it has to be discarded. Therefore, blood must be supplied safely and effectively because it is one of the medical resources which keep humanlife. In this study, the effects of blood issuing policies on average inventory levels and average age of blood at transfusion are determined by simulation applied the theory of absorbing Markov chains. And as a practical study, the daily demand distribution of blood is estimated by using the data of B General Hospital. The distribution estimated follows poisson distribution and the estimator of parameter estimated from the poisson distribution is 0.762. Simulation is done by using the parameter. The most important problem when control blood is the amount of outdata. So we compared random policy with Modified LIFO and Modified FIFO by using outdata. As a results it is shown that Modified LIFO and Modified FIFO by using outdata. As a results it Is shown that Modified LIFO and Modified FIFO present better issuing policy than Random Policy.

This article reports the developmental stability of individual differences in children's attachment qualities with their mothers and the relations between the preschoolers' attachment security to mothers and maternal parenting behavior. 24 infants were observed with mothers in the Strange Situation to assess the infant-mother attachment patterns at 16 months of age. After 3 years, attachment security was assessed using Attachment Q-Set, and the modified IPBI (Iowa Parent Behavior Inventory: Mother Form) was administered to mothers to assess their parenting behavior. Analyses revealed significant differences in children's attachment security scores by infancy attachment patterns. That is 11 of 12 children's attachment to mothers qualities were stable across the 3 year periods. The attachment security scores related positively to the responsive maternal parenting behavior. Changes in child-mother attachment quality over time were related to maternal responsiveness. Collectively, these findings were consistent with predictions from attachment theory.
