The purpose of the study is to suggest a conceptual framework for the vacation reading programs in promoting children's love of reading in public libraries. Within the conceptual framework of free voluntary reading (FVR), the study identified the concept of reading that public libraries should pursue in developing children's reading programs and analyzed current vacation reading programs that four public libraries in Seoul held during winter and summer vacations of 2013. More specifically, the study analyzed (1) their purposes, (2) durations, targeted children groups, the number of children users, (3) their instructors, (4) the content design of the programs, (5) selected books, and (6) completion certificates and rewards for participation. Lastly, the study discussed whether the programs satisfied the characteristics for promoting free voluntary reading and played the roles for vacation reading programs in public libraries. The results of the study suggest the need for shifting the current vacation reading programs to be more inclusive, so that more children can develop to learn love of reading.

The objective of this study is to develop the self-regulation program for senior class students of elementary school to improve willpower. The data on basic need for the self- regulation program was collected using a five-point Likert scale and the participants were 93 students from the fifth-grade and sixth-grade of elementary school. And 32 elementary school teachers participated in this study. The need-survey was conducted for the contents analyses and process elements of this program. Eight experts accomplished program structure and contents design performed by 2 tests on validity. This program consisted of making the student complete one target-behavior that caused him into developing willpower. Self-monitoring and rewarding are the strategy to develop willpower and the students who executed this program developed good attitudes.

일반적으로 사출성형법은 유동, 보압, 냉각과정등 크게 3단계로 나눌 수 있는 데 유동해석에 관한 수치해석은 Tadmor 등이 FAN(Flow Analysis Network) 방법을 도입하면서 실제 적용에 활발히 쓰이고있다. 그리고보압은 후충전 과정으로써 충전이 끝난후 수축된 부분을 보상하기 위해서 수행되는 단계이다. 본 연구에서는 실제 사출금형 제작 시 결정해야 될 냉각 채널의 위치, 크기, 수동에 대한 설계기준을 얻을 수 있는 냉각해석 프로그램을 개발하였다. 이를 위하여경계 요소법(Boundary Element Method)을 이용하였으며 일반적인 냉각 채널 즉, Annual, Baffle 및 Bubber등 에 대한 해석이 가능하도록 하였다.

A flywheel system which can compensate electric power is presented. The designed system has a capability of providing real and imaginary power instantaneously as well as storing energy. In this paper, a control algorithm is designed. The designed algorithm is to control the secondary side current of the wound rotor induction motor using voltage-based PWM inverter. The flywheel system has advantages in converter size and power quality improvement comparing to the conventional system.

본 논문에서는 NOP 이 차지하는 슬롯에 의미 있는 명령어를 중복 할당하여 자료의존 관계를 해소하고 프로그램 실행 사이클을 단축시키는 명령어 중복 스케줄링 기법을 적용할 수 있는 VLIW 구조인 TiPs(Tiny Processors) 구조를 제안하였으며 TiPs는 회로의 복잡도를 증가시키지 않으면서 실행시간을 단축시켜 가상의 바이패싱 회로를 추가한 효과를 얻을 수 있다. 실험 결과 TiPs에서 명령어 중복 스케줄링 기법을 적용할 경우 8% ～ 25%의 성능 향상 효과가 있음을 알 수 있었다.

Previously, studies on compensation material to increase the signal intensity have been conducted which does not affect the reading of images. However, the compensation material has a concern on patient infection as it is attached directly on the skin. Therefore, in this study, we tested an indirect attachment of the compensation material as an alternative method of the direct attachment. The silicon compensation material was fabricated in the form of a cylindrical bar and attached to each element of the 8 channel head coil. Then the signal intensities of the water phantom pre and post application of the silicon were measured. T1 and T2-weighted images were acquired using an 8-channel head coil and a 3.0T superconducting MRI. Signal intensities were measured by using an image measuring program. Paired t-test was used to verify if there were significant differences. The signal intensity before application of the silicon was significantly increased by 3.39% and 2.62% in T1 and T2 weighted images, respectively. Although the indirect attachment method had a limitation to completely replace the existing method, it was considered to be useful in patients with infectious diseases such as diabetic complications since it had a meaningful improvement in signal intensity based on the filling factor increase.

This study compared the activities satisfaction factors between volunteer firefighters and general volunteers in Sejong City. For this purpose, 112 volunteer firefighters and 227 general volunteers working in Sejong City were surveyed. In the questionnaire, the independent variable was the motivations, the interpersonal relationships, and the rewards and the dependent variable was the activities satisfaction. The reliability of the survey data in questionnaire design was analyzed by the SPSS 20.0 win program. The factor of the motivations, interpersonal relationships, and rewards had a significant positive influence on the activities satisfaction of volunteer firefighters and general volunteers (<0.05). The activities satisfaction of the volunteer firefighters was influenced in the order of the motivations, rewards, interpersonal relationships, and activities satisfaction of the general volunteers was influenced in order of the motivations, interpersonal relationships, and rewards.

This paper suggests a new algorithm which minimizes the bit dimension of control memory considering the flexibility for reprogramming in the microprogrammed digital systems. The algorithm can not only minimize the bit dimension but also compensate the loss of flexibility by giving a highest MOP the unique field in the process of bit minimization. Also, programming the algorithm, that result and previous works are compared and reviewed. Then the bit reduction and the improvement of flexibility are proved.

현재 PWR에서는 반응도 변화를 보상하기 위해서 강한 중성자 흡수체인 수용성 붕소가 사용되고 있고 수용성 붕소내의 $B^{10}$은 연소하게 된다. 최근 대부분의 발전소가 장주기 운전전략을 채택하고 있고 발전소 이용률이 증가하고 있어 $B^{10}$ 연소의 중요성이 부각되고 있다. 본 연구에서는 국내의 웨스팅하우스형 3-Loop 발전소에 대해 $B^{10}$의 연소거동을 모사하는 프로그램을 개발하여 $B^{10}$ Percent를 연소도의 함수로 계산하였고 실제로 냉각재내의 $B^{10}$ Percent를 측정하여 검증하였다. 또한 $B^{10}$ Percent 변화에 따른 Boron Letdown Curve를 보정하여 측정값과 비교, 검증하였다. 검증결과 $B^{10}$ 예측 프로그램의 예상값과 측정값이 비교적 잘 일치하는 것으로 나타났다. 따라서 발전소에서 나타나고 있는 임계붕산농도의 설계값과 측정값 간의 일반적인 차이에 대한 원인이 규명되었고, $B^{10}$ 연소에 의한 상대적인 흡수체의 감소는 정지여유붕소량 계산시 고려되어야할 필요성이 있는 것으로 나타났다.
