The purpose of this study was to investigate implications of self-directed learning experiments in elementary science education through understanding elementary school students' awareness of their experiences in self-directed learning experiments. Twenty students joined the school science club voluntarily and conducted self-directed learning experiments. We collected data through observation of the experiments, interviews, and questionnaires. The students who participated in the club showed high satisfaction with self-directed learning experiments. The participants were aware that their scientific interest and knowledge, and the confidence in conducting experiments were increased. The students felt positive about the inquiry process of conducting self-directed learning experiments with their own subjects. They also felt a sense of achievement in attempting their experiments in defiance of several failures. The participants realized that the self-directed inquires led to increased declarative and procedural knowledge of science. The students stated that they had some difficulties in coping with the different results contrary to expectations and preparing laboratory materials and instruments. Nonetheless, they showed the promotion of their scientific literacy during overcoming those difficulties. We suggest that self-directed learning experiments can be a more effective way in science learning to make students experience the nature of science than existing school experiments. This can be implemented through a creative experience activities such as science clubs.

The purpose of this study is to examine the effects of soccer club teachers' leadership behavior types on elementary and middle school students' psychological factors. The subjects in this study were 561 students who consisted of 245 elementary and 316 middle school students - from 15 elementary and 17 middle school teams. All the teams are registered in the Busan Sports Club. The findings of the study were as follows : Autocratic behavior must be used rarely because it causes great anxiety. Positive feedback behavior is needed to improve students' confidence. Positive feedback behavior and training and instruction behavior are needed for achievement motivation. For this reason, teachers must coach students through positive feedback behavior, training and instruction behavior and social support behavior to build confidence, achievement motivation and cohesion. Since confidence, achievement motivation and cohesion depend on careers, coaching student's early helps students perform better.

The structure of skin of a mud loach Misgurnus anguillicaudatus was described in relation with their histochemical nature from four regions of the skin. The epidermis has a strongly thick layer of two glandular cells, consisting of a elongate mucous cell and club cell, and a thin layer of superficial layer. The secretion of the elongated mucous cell was acid mucopolysaccharides in nature but the club cell did not give any histochemical reaction. A well defined lymphatic system, comprising small lymphocytes was present in the stratum germinativum layer of the epidermis. A pit organ of a pear-shaped structure was present below the epithelial cells and lie directly on the basement membrane. The organ has blood vessels serving the sense organs of the epidermis. There was a definite area showing acid mucopolysaccharides in the stratum laxum layer of the dermis. Small scales are present deep in the dermis except the top of the head. A great number of blood capillaries were found just under basement membrane. These structural features of skin in M. anguillicaudatus seem to be closely related with cutaneous respiration using air.
