The purpose of this study was to examine the relationship between social networks and perceived self-competence. The subject were 350 third and sixth graders selected from a public elementary school in Seoul. The children were administered the Pattison Psychosocial Network Inventory and The Self Perception Profile for Children. Three major questions are addressed; l)age changes 2)sex differences, and 3) the relation between the characteristics of social networks and self-perceived competence. Data were analyzed by pearson's product moment correlation, one-way ANOVA. Proportion measures were also used since they had allowed for the observation of relationship between two subsets of people within given categories(e.g.,the number of relatives divided by the number of relatives plus nonrelatives). The effects of age and sex of child on the number and daily contact with kin, nankin, peers, adults, males, and females were found. Sixth graders had a larger number of adults than third graders. While children had a greater number of adults than peers, they had more contact with peers than with adults in their network. It was found that boys had greater number of people in their network than girls. And boys had a larger number of and more contact with males, and girls had a larger number of more contact with females. The structure of childrens' social networks structure were correlated with perceived self-competence.
The objectives of the present study were to investigate the relationship between self-concept and clothing buying pattern in accordence with their self-concept. The method employed to conduct this study was normative-descriptive survey using questionnaires. Subjects were 438 high school girls in Seoul and the survery was implemented from the begining of May 1998 to the end of June 1998. The questionnaires were completed by students during class. Mean Standard Deviation Chi-Squeare and t-test were employed to analize the data gathered. The results are summarzed as follows: (1) The group who has the higher score in total positive self, self identity self satisfacton self behavior physcial self moral ethical self personal self and family self cares more about economical efficiency of clothing than the group who has the lower score. (2) The group who has the higher score in total positive self, self satisfaction personal self and family self attachs greater importance to the practical use of clothing than those who scored lower with in said categories of self concept. (3) The group who has the higher total positive self score cares originality more than the group who has the lower score when they purchase outdoor garment. (4) The group who has the lower social self score cares modesty and ostentation more than the group who scored higher in social self. (5) The group who has the higher score in positive self behavior personal self and family self cares about convenence in care and maintenance of the clothing than the group has the lower score. (6) Friends buying and use experiences of herself and the observation of other's attire are the main source of fashion information for the present Korean high school girls. The group who has the higher score in total positive self personal self family self, self identity self satisfactio self behavior used their own experiences more often as a source of fashion information than those who scored lower with in said categories of self concept. The group who has the higher score of total positive self personal self family self, self identity self satisfaction self behavior uses family members more often as a source of fashion information than those who scored lower with in said categories of self concept. The group who has the higher score in self identity and self behavior uses store displays more often than the group who scored lower. (7) Bonded processing goods stores or fancy goods shops(haberdashery) located in trendy shopping district discount stores and outlet stores of the famous manufactures are main places where Korean high school girls buy their outdoor garments.

This paper aims to excavate and make storytelling of cultural landforms around Shincheon, Geumho river in Daegu and then to build the strategy for making its application. The main results are as follows. 1) There are main cultural landforms such as Yongdubawi(龍頭岩, river cliff), river cliff, rock shelter(岩蔭), sheeting joint landform, river cave, tor, etc. around Shincheon. 2) there are main cultural landforms such as riverine wetland, ferry, point bar, river cliff, Hwadam(畵潭, pool), Donghwacheon(stream), Mutae(無怠), Chimsan(hill), Yeonamsan(hill), Sanghwadae(river cliff), etc. around Geumho river. 3) It is necessary to excavate and restore cultural landforms around Shincheon and Geumho river for protection, Also the valuable cultural landforms should be designated as cultural assets in order to prevent damage. 4) Considering from application of cultural landforms around Shincheon, natural observation site need to be designed for experiencing culture, history and ecological environment. However, in viewpoint of application of cultural landforms around Geumho river, it is much better to plan a few of Geumho river cultural landform trails for self-guided tour.
Purpose: The purpose of this research was to develop and train caregivers in tracheostomy tube care using a self-management program to assist patients with an 'at home' tracheostomy procedure. Caregivers' self-efficacy and knowledge of tracheostomy management before and after the training was also identified. Methods: Research participants were the main caregivers for patients with tracheostomies who were affiliated with a 'Home Healthcare Center'. Training and observation were done at 'A Hospital' and 'G Hospital' both affiliated with 'K University' in Seoul. Data were collected from May 3, 2010 to January 25, 2011 and analyzed using Wilcoxon signed rank test with SPSS program version 12.0. Results: Significant differences were found for the pre and post evaluation of the 'self-management program' for the implementation of tracheostomy care. The development and implementation of the 'self-management program' improved the main caregivers' knowledge of tracheostomy tube management (Z=-3.599, p<.001). Conclusion: Results show that this program has identified an effective nursing intervention for promoting the caregivers' knowledge of tracheostomy care and self-efficacy. We recommend that further research should be done to test primary caregivers' maintenance of knowledge and self-efficacy in tracheostomy tube management and identify factors affecting knowledge and self-efficacy in the care of these patients.
The Korea Astronomy and Space Science Institute (KASI) has been developing a next-generation coronagraph (NGC) in cooperation with NASA to measure the coronal electron density, temperature, and speed simultaneously, using four different optical filters around 400 nm. KASI organized an expedition to demonstrate the coronagraph measurement scheme and the instrumental technology during the 2017 total solar eclipse (TSE) across the USA. The observation site was in Jackson Hole, Wyoming, USA. We built an eclipse observation system, the Diagnostic Coronal Experiment (DICE), composed of two identical telescopes to improve the signal-to-noise ratio. The observation was conducted at four wavelengths and three linear polarization directions in the limited total eclipse time of about 140 seconds. We successfully obtained polarization data for the corona but we were not able to obtain information on the coronal electron temperature and speed due to the low signal-to-noise ratio of the optical system and strong emission from prominences located at the western limb. In this study, we report the development of DICE and the observation results from the eclipse expedition. TSE observation and analysis with our self-developed instrument showed that a coronagraph needs to be designed carefully to achieve its scientific purpose. We gained valuable experience for future follow-up NASA-KASI joint missions: the Balloon-borne Investigation of the Temperature and Speed of Electrons in the Corona (BITSE) and the COronal Diagnostic EXperiment (CODEX).
Objectives: This study analyzed the perception towards clinical practice education content held by dental hygiene students in dental institutions and their perceived importance of dental hygienists' clinical duties. Methods: The subjects of this study were 182 dental hygienists who were working at dental institutions in Seoul, Gyeonggi, and Chungcheong areas. A survey was conducted with a self-administered questionnaire. In the questionnaire, the clinical practice contents were classified into observation, preparation, and performance, and the importance of clinical duty was measured with a 3-point scale. For the clinical practice contents and the importance of duty, descriptive statistics and chi-square test were performed, and the study results were analyzed using STATA 11.0. Results: With regard to clinical practice contents, observation was mainly performed in oral & maxillofacilal radiology, preventive dentistry, periodontal medicine and oral medicine. In primary care and infection control, practice and observation were mainly performed. In the department of orthodontics and pediatric dentistry, observation and preparation were mainly conducted, while in oral surgery, conservative dentistry observation, preparation and practice were all conducted. With regard to clinical practice contents according to the dental institution, there were statistically significant differences in the type of dental institution and the duty (p>0.05). In terms of the importance of dental hygienist's duty, infection control, toothbrushing education for each patient, removal of plaque, and patient education after surgery were considered important. Conclusions: For clinical practice of the dental hygiene department, the education contents should be standardized in accordance with the importance of the dental hygienist's duty, a protocol for operation of practice should be developed, and a method of standardization of evaluation should be sought in the future.

This paper presents the variable perturbation and observation(VPO) maximum power point tracking(MPPT) control of the photovoltaic(PV) system considering the shadow influence. The output characteristics of the solar cell is a nonlinear and affected by a temperature, the solar radiation and influence of a shadow. MPPT control is a very important technique in order to increase an output and efficiency of the solar power generation. Conventional perturbation and observation(PO) and incremental conductance(IC) are the method finding MPP by the continued self-excitation vibration. The MPPT control is unable to be performed by rapid output change affected by the shadow. To solve this problem, this paper proposes the VPO MPPT algorithm which changes step size according to output variation. The response characteristics of VPO MPPT algorithm proposed in this paper compares with response characteristics of conventional MPPT algorithm about the radiation, temperature and shadow influence. The validity of the algorithm proposed in this paper prove through the results of the comparisons.
