Though the history of fisheries business administration education has it's own uniqueness, the research or study of that still insufficient. And in spite of the structural shift of society and environmental diversity, there's few research that analyzing or examining the curricular constitution and change recently. The process of this research was implemented with investigating the objective and content domains concerning marine education in the fisheries and marine curriculum and changes of them. The changes of fisheries business administration education reviewed and analyzed in the view point of construction of the textbook, contents of the each changes and recency comparison of tables and figures of the high school textbook of the fisheries business administration general. The results show that most of the changes have been reflected by the demands of the society including fisheries related law, policy and distribution networks. But there are still some errors and necessity of improvements in data and descriptions. The results of this study would help develop sustainable curriculum design for further changes and give more effective guidelines for identifying the core of fisheries business administration education.

This paper presents a study on a high-performance design for a block cipher algorithm implemented on modern many-core graphics processing units (GPUs). The recent emergence of VLSI technology makes it feasible to fabricate multiple processing cores on a single chip and enables general-purpose computation on a GPU (GPGPU). The GPU strategy offers significant performance improvements for all-purpose computation and can be used to support a broad variety of applications, including cryptography. We have proposed an efficient implementation of the encryption/decryption operations of a block cipher algorithm, SEED, on off-the-shelf NVIDIA many-core graphics processors. In a thorough experiment, we achieved high performance that is capable of supporting a high network speed of up to 9.5 Gbps on an NVIDIA GTX285 system (which has 240 processing cores). Our implementation provides up to 4.75 times higher performance in terms of encoding and decoding throughput as compared to the Intel 8-core system.

본 연구는 분자생물학 기초 소양 함양을 위한 제한 효소 지도 작성의 탐구실험을 구성하였고, 일반계 고등학교 2학년을 대상으로 학생 중심의 제한 효소 지도 작성 탐구실험 수업을 통해 탐구실험 능력과 과학긍정경험에 미치는 영향을 분석하였다. 우선, 탐구실험 수업이 일반계 고등학생의 과학긍정경험에 있어 '그렇다' 이상으로 응답한 비율이 사전에 비해 사후에서 높은 것으로 보아 유의미하게 효과가 있는 것으로 나타났다. 제한 효소 지도 작성을 위한 연속의 5단계로 구성하여 적용한 결과 학생들의 과학 분야 학업에 대한 흥미 유발뿐만 아니라 학생들의 수업 참여도가 높아졌고, 구체적인 과학 학습 동기, 과학 진로 포부 및 체험 자료로도 효과적인 것으로 나타났다. 탐구실험 수업의 과학 환경이 학생들의 학습 태도와 과학긍정경험의 향상으로 이어져 수업의 집중과 수업의 질적 향상, 학생간의 적극적인 의사 소통과 상호 협력의 중요성에 긍정적인 영향을 끼쳤다. 또 탐구실험 수업이 진로 체험의 기회를 제공함으로써 분자생물학의 기초 소양 함양과 이공계 진학의 토대가 될 것이다.

Owing to generalization of design competitions since 1990s, various design methods was tried in elementary middle high school design competitions. Therefore, to analyze design characteristics of elementary middle high school is very meaningful. In this context, this study is the most important purpose for analyzing layout plans and their trends in prizewinners of elementary middle high school design competitions and for furnishing basic datum for next school design. The result of this study is following : (1) The layout patterns of school buildings are classified into 12 types. (2) Entrance design is divided into 6 types(structure, column and wall, open, half structure, general, and mixed type). (3) Square design is grouped into 7 types. (4) Pedestrian mall is sorted out 6 types(straight lineal, curve, curve and square, straight lineal and curve, and straight lineal and curve and square type). (5) Entrance types of vehicle and pedestrian are classified into 4 types(parallel, ㅡ separation, ㄱ separation, and opposite separation type) Analysis shows that the best applying for layout patterns of school buildings is ㄷ type and ㅌ type, for entrance design is structure type, for square design is ${\square}$ type and ${\bigcirc}$ type, for pedestrian mall is straight lineal and square type, and for entrance types of vehicle and pedestrian is parallel type.

This study was performed to investigate the awareness of the value on milk and the consumption pattern on milk of elementary, middle and high school students. The subjects were 453 students(129 elementary, 129 middle, and 195 high school students) living in the Seoul area. The results were as follows. The students of this study demonstrated low levels of awareness of the value of milk. They had an awareness of the value of milk about 'convenience', 'healthful', 'safety', 'diversity', and 'useful for snack'. Most students reported drinking milk two to three times a week and 13.2% of students preferred flavored milk rather than plain milk. General preference for milk was significantly higher in elementary school students than in high school students(p<0.001). The degree of satisfaction on milk was significantly higher in elementary school students than in middle and high school students(p<0.001). The respondents answered that their source of information about milk was the mass media. Their source of information from school was very low. In order to increase the consumption of plain milk, milk nutritional education is necessary in schools.

This research aims to examine the influence of Korean high school girls' perceived family adaptability and cohesion on maturity with regards to career attitude. In order to verify statistically the research questions, Cluster Sampling with Stratification was conducted among high school girls in Seoul; a total of 670 questionnaire sheets were administered to 10th graders；and Multiple Regression was used for data analysis. Subsequently, the following results were obtained： a high school girl's perceived family adaptability and cohesion significantly influenced her maturity with regards to her career attitude. Particularly, the sub-variables such as democratism, participation, supportiveness, and unity of family adaptability and cohesion had significant relevance to career attitude maturity. In general, family adaptability and cohesion had an R square of 47.3% with regards to a female 10th grader's career attitude maturity.

The Euclid metric is well-known and there are many results on the space with that metric. But there are many other metrics which gives more practical and useful results in the plane. In this paper, we introduce new metric function in the plane, which is more useful in city with subway. Finally we generalize to the general metric space and introduce a new metric on ${\mathbb{R}}^n$.

Objectives : The aim of this study is to investigate dental clinic fear and anxiety in high school students. Methods : The subjects were 311 high school students aged 19 years. They completed self-reported questionnaire including general characteristics, dental clinic experiences, dentist or dental hygienist confidence, and dental fear. Data were analyzed using SPSS 18.0. Results : Poor oral health status showed negative attitude towards dental clinic visit. Girl students tended to have more fear than boy students. Muscle tension was the most common experience and was closely related to anesthetic needles and drills. Dental anxiety was caused by lack of confidence to dentists and dental hygienists. Students were more afraid of dentists than dental hygienists. Higher score of dental anxiety seemed to be associated with infrequent visit to dental clinic. Conclusions : Frequent regular dental checkup may reduce dental fear and anxiety. Dental clinic staff should try to minimize dental anxiety in performing treatment.

We introduce a new degree reduction method for homogeneous symmetric polynomials on binary variables that generalizes the conventional degree reduction methods on monomials introduced by Freedman and Ishikawa. We also design an degree reduction algorithm for general polynomials on binary variables, simulated on the graph coloring problem for random graphs, and compared the results with the conventional methods. The simulated results show that our new method produces reduced quadratic polynomials that contains less variables than the reduced quadratic polynomials produced by the conventional methods.

본 증례는 유구치부의 치아우식증을 주소로 내원한 누난 증후군 환자의 전신마취 하 치과치료에 대한 보고이다. 누난 증후군 환자의 특징적인 안모가 관찰되었으며, 높은 아치형의 구개와 작은 턱이 관찰되었다. 성장 지연, 발달 지연, 가슴 기형, 언어 지연을 보였다. 누난 증후군 환자는 다양한 전신질환을 동반할 수 있으므로, 치과 치료 시 전신적인 상태에 대한 고려가 필요하며 이와 더불어 행동 문제를 보이는 경우가 많아 행동 조절에 대해 고려해야 한다. 누난 증후군 환자의 전신마취 시 기도 문제, 심폐 기능의 손상 등이 문제가 될 수 있으므로, 이에 대한 평가가 필요하다.
