This study is an attempt to provide some answers to question about how characteristics and general recognition regarding internet use in Korea and Japan influence fostering and maintaining on-line social network in each of countries. Survey is used to compare Korean internet users and Japanese internet users in terms of characteristics of on-line social network, individual's propensity for internet use, including their recognition on internet. The study's main findings go as follows. First, Korean internet users tend to be more active in using internet than Japanese internet users do, thus having larger on-line social network and more intensive internet use than Japanese internet users do. However, there is a commonality that majority of internet users in both countries use internet to connect them to person with whom they have private relationship but they cannot meet frequently. Second, for Korean internet users, individual's propensity, characteristics, and recognition regarding internet use is not related to how to contact others. To the contrary, for Japanese internet users, how to contact others in on-line setting seems to vary according to whether or not they have relation-oriented internet use and how they recognize the availability of internet. Third, a commonality regarding the size of on-line social network is found between Korea and Japan that the total numbers of people enrolled as network increases if people use internet in order to get information. This confirms previous finding that relationship based on weak tie is instrumental in fostering on-line social relations and likely produces advantage in getting information. Finally, for Japanese internet users, the degree of risk recognized in on-line setting, that is the degree of interpersonal trust, appears to greatly influence overall relationship -building in on-line.
During the term of June, 7 to August 11, the noises in the maine engine room in terms of the r. p. m. of the Pung-Yang Ho (4,500 H. P.), the Chuk-Yang Ho (3,800 H. P.), the Dong-Bang Ho (3,000 H. P.), the Oh-Dae San Ho (2,690 H, P.), the Kwan-Ak-San Ho (1,000 H. P.) and the Back-Kyung Ho (850 H. P.) (Refer to Table 1) were measured with the use of sound level meter, which has measuring range 37-140 dB and the results obtained are as follows : 1. Capacity of the engine room becomes large according to the total H. P. of the main engine, but the vessels are using of a type of engine, i.e., 6 cylinder, and thus the noise, pressure has shown a tendency to become lower except Kwan-Ak-San Ho, Chuk-Yang Ho and Dong Bang Ho where the noise pressure was higher by 3 dB than curve of mean value. 2. The maximum noise pressure appeared even before the main engine reached the maximum r. p. m. and while the percentage of the r. p. m. varied depending on the vessel, the maximum noise appeared at around the $67-75\%$ of the r. p. m. 3. The maximum of noise pressure in the respective engine room ranged between 93.5-105 dB while it was between 72-81 dB at the fish process room in the stern trawl vessel where the oral communications were possible.
The 167 plus tree clones of Pinus koraiensis in clone bank planted in 1983 were investigated for time of flowering, rate of flowering, and number of flowering from 1986 to 1989. The results were as follows : 1) There were clones in the minority which do not cross in natural pollination between earlest flowering female clones and latest shedding male clones. 2) The rate of male flowering appeared less than rate of female flowering and received influence of genetic more than rate of female flowering. 3) The numbers of flowering in female and male flower were affected by small number of clones. 4) The flowering number for female strobili was not related to the flowering number of male flower. The 42 clones among 167 clone had not male flower. 5) The flowering number of 167clones were classified three groups in female flower and four groups in male flower by L.S.D 5% test. 6) The clones with abundant female and male flower were selected based on the component analysis. 7) As Based on flowering rate and number of female, the juvenile phase of plus tree clones appeared to be until four years after grafting ; the transition period appeared to be from five to seven years after grafting ; the adult phase appeared to begin from eight years after grafting, 8) The grafted trees of Pinus koraiensis appeared early flowerring about six years compared with seedling trees.
I will critically argue the Mencian idea of sharing pleasure with the people in the light of happiness as emotion. Happiness as a subjective mental state can make troubles with good life in being at odds with real lives. Thus, what pursues genuine happiness goes back to a classical question of how one ought to live for good life over the subjective mental state. For this, I will focus on concepts of 'pleasure alone (tongnak)' and 'sharing pleasure with the people(yeomin-dongnak)', which can be seen in the dialogue between Mencius and King Xuan of Qi. I will show that king Xuan's pleasure as subjective happiness has discord with his good life because of the hierarchy of his desire. I will explain how to unify good life with pleasant one by the idea of sharing pleasure with the people provided by Mencius and examine certain dynamics of sympathy and mutual understanding under solidarity. Moreover, I will investigate how such power of sympathy as compassion can be connected with sharing pleasure with the people. Compassion and yeomin-dongnak can be captured by the golden rule of a measure to gauge others(shu). I will delve into how to differ from one another and summarize Confucian idea of yeomin-dongnak as happiness in terms of the theoretical frame related to good life(welfare). I briefly conclude how subjective happiness can contribute to making our lives better.

This study aims to explain the key concepts and principles of text-based generative artificial intelligence (AI) that has been receiving increasing interest and utilization, focusing on its application in science education. It also highlights the potential and limitations of utilizing generative AI in science education, providing insights for its implementation and research aspects. Recent advancements in generative AI, predominantly based on transformer models consisting of encoders and decoders, have shown remarkable progress through optimization of reinforcement learning and reward models using human feedback, as well as understanding context. Particularly, it can perform various functions such as writing, summarizing, keyword extraction, evaluation, and feedback based on the ability to understand various user questions and intents. It also offers practical utility in diagnosing learners and structuring educational content based on provided examples by educators. However, it is necessary to examine the concerns regarding the limitations of generative AI, including the potential for conveying inaccurate facts or knowledge, bias resulting from overconfidence, and uncertainties regarding its impact on user attitudes or emotions. Moreover, the responses provided by generative AI are probabilistic based on response data from many individuals, which raises concerns about limiting insightful and innovative thinking that may offer different perspectives or ideas. In light of these considerations, this study provides practical suggestions for the positive utilization of AI in science education.
This research aims to make people realize the importance of styles of father's communication and ego-resilience in school life adaptation and, furthermore, provide necessary data for the communication between father and children by confirming the mediation effect of ego-resilience in the relationship between the styles of father's communication, which the child recognizes, and the school life adaptation. The selected research questions to achieve such research purpose are like the following. First, what is the correlation among school life adaptation, ego-resilience, and communications styles of father that child recognizes? Second, does the ego-resilience show mediation effect in the relationship between the school life adaptation and communication styles of the father that child recognizes? The subjects for this research were 345 children in 5thand 6thgrades from B elementary school in Seo-gu, Incheon. SPSS 18.0 program was used for the collected data, and correlation analysis was performed in order to discover the relationship among variables. Regression analysis was performed to verify the mediation effect of ego-resilience. The summary of this research is like the following. First, as the result of the correlation analysis of the father's communication styles, ego-resilience and the school life adaptation, which the child recognized, the three variables showed statistically significant correlation. Among the functional and dysfunctional communication styles that child recognized, the placating style showed positive correlation with ego-resilience and school life adaptation, and among dysfunctional communication styles, the intellectualizing style, distracting style, and blaming style showed negative correlation with ego-resilience and school life adaptation. Ego-resilience and school life adaptation showed positive correlation. Second, after looking at the mediation effect of ego-resilience in the relationship of the father's communication style and school life adaptation, the result showed that ego-resilience had partial mediation effect in the relationship of the father's communication style and school life adaptation. In this research, it has significance in the aspect that it confirmed the relationship and route between the father's communication styles, school life adaptation, and ego-resilience, which child recognized. Therefore, the effort is required to research and apply desirable communication method between fathers and children in order to help students to adapt well in school life, and moreover, it is also required that ego-resilience improvement program gets developed and applied at the school field.
Purpose - This study aimed to investigate the correlation between the social activity of the elderly and recognition of family cohesion of the elderly who are exposed to the current aging society. In addition, the study has delved into the method of family cohesion improvement through the differences between groups based on the mediator effect of how the results have effects on the elderly's self-control capabilities. Research design, data, and methodology - This study has targeted the elderly who are attending the elderly university among users in seven community centers located in Seoul and Gyeonggi-do area. The study has also conducted a survey by the format of a half-structured questionnaire. It is aiming to investigate the elderly's family cohesion with children and their self-control capability, and understand their satisfaction of social activity to help successful elderly life. The study has suggested the following as mentioned. First, the study analyzed that the perceptual factor of family cohesion with children would be deducted based on advanced researches. Second, the influencing relationship would be analyzed through the relational analysis between the elderly's family cohesion and social activity. Results - The family cohesion with children has a significant effect on psychological happiness and it showed the influencing relationship with improvement of the elderly's self-control capability. Therefore, creating fellowship through meaningful conversation with children would be needed. In addition, various programs and consultant service would be offered to build healthy relationship between aged parents and their children. Through this, the elderly will be able to have not only better relationships with their family, but also increased psychological health and well-being as well. Conclusions - It is needed that not only supporting policies for children who take care of aged parents but also that the elderly who need long-term care could meet their children whenever they want through increased numbers of sanatoriums operated by cities and countries. In addition, the nation would offer financial and administrative support continuously so that people receive the benefits from sanatoriums located in the locality of children's residence beyond the elderly's residence. Moreover, social infra would be established as well.

The purpose of this research is to share the experience of reflective practice of a Home Economics teacher professional learning community(PLC) operator and to share better suggestions through reflection on PLC operation. All conversation in the 18 sessions of the PLC totally from May 31st 2013 to May 19th 2014 was recorded and transcribed. All materials of PLC activity were qualitatively analysed. Its themes were grounded on its coding and categorization scheme. Findings and conclusions of this study are as followings. The experience of learning the PLC for a year has found that it is the power to keep the PLC alive: courage and anxiety to face anxiety and anxiety about new challenges, the importance of theme selection, a teacher with a reckless challenge, shares of becoming a leader. Through reflection, I learned that concerns require attention to other teachers and the need for a 'New Round' for ongoing meetings. I, as a operator, did not fully consider participant's different interest as well as a program for a new round due to the lack of management experience. It led to the low participations in latter sessions of PLC. Suggestions are put as solutions to improve these problems; (1) grouping participants by school levels when collecting participants, (2) setting operation period and program applying participants' opinions, and (3) operating short-term PLC with certain themes to immerse reaching goal and satisfaction in short time.
In this study, noise arresting effect of the noise control room from the transmission of surrounding noise was tested when the packing noise control rooms were set up in the test room in which the prerecorded noise from an engine room was reradiated at the same level as the original pressure. The inner space of control room A is $3.389m^3(1.19\times1.19\times2.14m)$ having walls furnished with plywood board 9mm in thickness and noise control room door$(60\times45cm) $ and illumination lamp are placed. In case of the control room B, noise absorption board(10mm fiber board which holds the corntype concavity with diameter of 5mm, depth 5mm, space 15mm) is adhered to the internal ceiling and styrol foam boards(20mm) to the walls. The other struction is same as the control room A. Type C is the same as B except wool board(Glass Fiber, 33mm) on the walls. Type D is same as type A except that the thickness of wall is 12mm and wood pyramid type cone$(5\times5\times13cm)$ is adhered to the ceiling ana walls(Fig. 1). When the recorded noise and vibrated noise were controlled in various levels. The noise pressure which passed through the control rooms was measured by sound level meter(Bruel & Kjar 2205, measuring range 37-140dB). In order to calculate the absorption rate in the control rooms the noise pressure was measured at different distances when the recorded noise pressure was radiated. The followings are the results obtained from the experiment. 1. When the noise pressure of the test room was 60dB, transmission rate of type A was $69.7\%$ and increased $3.3\%$ per 10dB. At the same condition, the rate was $53.9\%$ and increased $4.5\%$ per 10dB in type D. Type D was the most effective in noise arresting of the four and the effect was D,C,B and A in order(Fig.2). 2. When the oscillator sound and vessels noise were radiated in 1,000Hz, at one meter distance to the type A and D, the oscillator sound pressure were 77dB and 73dB, while the vessels noise pressure were 73.3dB and 66.2dB respectivley(Fig.3). 3. Refering to the influence of the frequency to the lower oscillator sound(1,000Hz) pressure, both type C and D were almost same at 140cm but type C was 0.3dB lower than type D at 20cm distance(Fig.4).
The study was intended to investigate how dentists in private dental clinic thought on the present claim and review of dental insurance to reflect it in future establishing dental insurance policies. 1,465 dentists who were running own dental clinic in Pusan Metropolitan City and the south part of Kyungsang province were surveyed in February, 2004. A total of 406 copies of finished questionnaire were finally retrieved and analyzed. The findings are as follows. 1. About insurance claim affairs : Most of the subject of insurance claim was by dentist himself or dental hygienist(nurse). Agency claiming was carried under 20% of total insurance claim. 2. The degree of attendance on insurance lecture : The degree of attendance on insurance lecture was relatively low. 3. Filing a protest against insurance claim : Filing a protest against insurance claim was reavealed about half-and-half for "have been" or "have not been". 4. Private clinic dentist,s opinion about the regulations affecting review of dental insurance : Private clinic dentists opinion about current guide for insurance review of dental fee was“the guidance is difficult and unfair cutback of claim fee may be carried”. 5. The affairs about health insurance review agency : About 70% of private clinic dentists have dissatisfaction on health insurance review agency. 6. Standpoint of private clinic dentists about issuance of receipt for dental fee : About 70% of private clinic dentist have an difficulty in issuance of receipt for dental fee. 7. The affairs about change insurance noncoverage treatment to insurance coverage treatment : Most of private clinic dentists hoped that insurance coverage about full mouth scaling, pit and fissure sealant, fluoride application. But they do not hoped that insurance coverage about geriatric denture, prothodontic treatment except precious metal, photopolymerization resin treatment.
