I-123 labelled fatty acids are suitable for investigation of regional myocardial metabolism, so they are on the clinical trial. However, the precise properties of these materials are not characterized yet. We have synthesized phenylpentadecanoic acid and labeled this compound with I-123. The purpose of this study was to examine the stability, biodistribution, metabolism and SPECT imaging of [I-123]15-(p-iodophenyl)pentadecanoic acid(I-123-IPPA) that we made. The stability test of I-123-IPPA in serum of rat, mouse and human showed no free I-123 after 1 hour. In biodistribution study in mice for various time intervals after injection(5, 10, 15, 30, 60 minutes), uptake in myocardium was 14.5%ID/g(5 min), and 1.9%ID/heart(5 min), while uptake in muscles was 2.6%ID/g(5 min). Myocardium to blood ratio and myocardium to lung ratio increased for 5 min after injection and then decreased rapidly. Chromatographic data of rat blood and urine showed that little PPA was found in blood and urine at 15-20 min after injection. The myocardial I-123-IPPA SPECT images of a dog with myocardial infarction showed defects similar to those of Tc-99m-MIBI and F-18-FDG. These data suggest that I-123-IPPA is quite stable in vitro and shows favorable biodistribution in mice. SPECT imaging with I-123-IPPA demonstrated infarct zone as photon defect in dog model of myocardial infarction. I-123-IPPA may be used for the evaluation of fatty acid metabolism in clinical trials in Korea.

The purpose of this preliminary study was to investigate the validity of the 'Attachment Q-set' as a measuring tool for 5 years attachment stability. The subjects comprised 18 boys and 15 girls aged 5 in a daycare center in G city, in Kyongnam. The instruments used in this study were 'Attachment Q-set', ASCT, and IPPA-R. Based on experts' rating, the Q-set was modified, reducing it from 90 to 75 items, and used a Likert 5-points scale. ASCT scores as well as types were compared with the scores of the Q-set and IPPA-R. The attachment type was classified into either secure or insecure. The IPPA-R score of the secure infants was significantly higher than the insecure, and correlated with the ASCT score. However, there was no significant correlation between the Q-set score with the attachment types or the ASCT scores. The Q-set scores were partially correlated with the IPPA-R. This results were discussed in terms of the Q-set's invalidity for rating attachment levels of 5 years as well as the limitations imposed by the subjects' restrictive numbers.

This study focused on the investigating of the improving measure of marine traffic system around Pyung-Taek Pilotage area. First, we analyzed the marine traffic environment on the study area based on the expert point of view of pilot and shipmasters. Then suggested the following countermeasures to improve the traffic safety according to the analytic results of the hazardous items on the Jangan-Seo and Ippa pilot embarking/disembarking area. We suggested to establish Mokdeok-do TSS and TSS in Ando area, and to adjust the width of Jangan-seo TSS to improve the congestion on the TSSs. Also suggest to put lightbuoys along the outer limit of the TSS. In addition, recommend to establish traffic safety specific area on the Jangan-seo/Ippa-do water, and to suggest expand the anchorage area of Ippa and Jangan-seo anchorage. It is anticipated to improve the traffic safety on the study area through the marine traffic system improvements.

This research was to investigated correlation between the mother and father's attachment and the parent motivation. The subjects were W university student 223 of Jeon-buk province. They took the parent-child relation courses. The questionnaire were IPPA[Inventory of Parent and Peer Attachment) and Parent Motivation Scale. The data were analyzed by t-test, Pearson correlation using the SPSS Program. The results were as follows: First, the university students who perceived the mother's attachment higher than the father's. Second, Parent motivation of the university students who perceived higher medium and the sex difference were no significance. Third, parent attachment were positively correlated with parent motivation. The finding from above results were that pre-parent education program of university students considered with the content that promotion to the parent attachment.

The primary purpose of this study was to explore the parent and peer attachment of both American parenting and nonparenting adolescents. Do parenting adolescents differ from nonparenting adolescents in their attachment to their parents and peers? A convenience sample of 190(81 parenting and 109 nonparenting) adolescents were recruited and participated in the current study. The short form of The Inventory of Parent and Peer Attachment(IPPA) developed by Armsden and Greenberg(1987) was used to measure attachment to their parents and peers. Overall, both parenting and nonparenting adolescents had more positive relationships with their peers than their mothers and only one significant difference in attachment between parenting and nonparenting adolescents were found in the present study. Parenting adolescents reported having less communication with their peers/friends than nonparenting adolescents. Implications and recommendations for future research are presented.

This study investigated the structural relationships between attachment, social competence, and emotion regulation. A survey was administered to 233 children of elementary school age(5th-6th grades) in G-city, Korea, using the IPPA-R, the Social Competence Inventory and an Emotion Regulation Scale. The collected data were then analyzed using a Canonical Correlation Analysis. First, the relationship between attachment and social competence was analyzed. The results showed that attachment and social competence have a positively correlated relationship. Peer attachments strongly affect the attributes of social competence when using a canonical variate analysis. Secondly, the relationship between attachment and emotional regulation was analyzed. The results showed that attachment and emotion regulation are also positively correlated. Maternal attachment particularly strongly affected the attributes of emotion regulation. Thirdly, the relationship between social competence and emotional regulation was analyzed. The results showed that social competence and emotional regulation have a positive relationship.

This study examined the relationships among children's attachment to the mother, trait anger, anger expression style, and emotional-behavioral problems in children. The subjects were 384 5th and 6th graders at elementary schools in J and G cities of Jeonbuk-Do. The instruments were Revised Inventory of Parent and Peer Attachment (IPPA-R), Stat-Trait Anger Expression Inventory - Korean version (STAXI-K), and Strength and Difficulty Questionnaire (SDQ). The major results are as follows; The level of children's attachment to the mother was negatively related to anger and emotional-behavioral problems, and the level of trait anger was positively related to emotional-behavioral problems. Children who have high anger expression and anger suppression tended to show more externalized behavior problems. Finally, the regression analysis showed that children's attachment to the mother and anger are revealed as significant factors in emotional-behavioral problems.
