There are need to develop of merchandise of value added fresh ginseng because of high consciousness level of consumer and enlarge of markets for high quality products. The fresh ginseng after harvest was distributed to farmer partually but in general, it was to market by consigner or wholsaler directly after harvest. There were a high difference on storage period of fresh ginseng in different harvesting seasons. The reduction of value of commodities of fresh ginseng for storage period was caused by decomposition and tender of tissue. The storage temperature was under the freezing point and the packing method was sealing tightly by plastic film. As the quality of fresh ginseng was defined by naked eye, it was difficult to sort the quality of ginseng directly harvest.

The purpose of this study is to examine the viability of PDL cells in rat molars by using MTT assay and to verify the MTT assay through the histologic observation. Thirty of Sprague Dawley white female rats of 4 weeks old with a body weight of about 100 grams were used. Groupings are as follows : Immediate Group : Positive control group(n=10) after extraction immediately. Dried Group : Negative control group(n=10) after drying for an hour under warm dry. ViaSpan Group : 1hour ViaSpan group(n=10) after storing in ViaSpan at 4℃ for 1hour. Ten teeth of each group were treated as same as above and replanted to the original socket of experimental animals. After two weeks of replantation. all the experimental animals were sacrificed. And after fixation, extracted maxillary jaw was dimineralized. After it was embedded in paraffin. serial section by ViaSpan was carried out and for construction of specimen, hematoxylin eosin dye was used. The mean MTT measurement of immediate group(positive control) is 2.81 and the mean measurement of dried group(negative control) is 0.98 which is significantt differnt(P<0.05), The mean measurement of ViaSpan group is 2.65 and there is significant difference between dried group and ViaSpan group(P<0.05), However, there is no difference between immediate group and ViaSpan group. The average resorption points of immediate group is 3.03 points. In the dried group, average 6.44 points resorption and 2.68 points showed resorption in the ViaSpan group. Unlike with MTT assay, there was no significant difference between the immediate group and ViaSpan group. The usage of MTT assay as a viable cell marker may give us a better indication of the maintenance of periodontal ligament cell vitality.

Background: The aim of this study was to determine whether the conventional subcostal approach is suitable for emergency pericardiocentesis in patients with cardiac tamponade or impending cardiac tamponade. Methods: This study was a prospective, observational study conducted at the emergency department of a tertiary hospital, Patients who had symptomatic pericardial effusion and who needed emergency pericardiocentesis in the emergency department were included in this study. We measured the epicardium-to-pericardium distance at the subcostal, parasternal, and apical area with two-dimensional echocardiography to determine the appropriate puncture site for pericardiocentesis. An epicardium-to-pericardium distance of more than 1.0 cm was considered as the primary safety factor in determining the Puncture site for pericardiocentesis. The skin-to-pericardium distance was considered as secondary safety factor. Results: Ninety-five consecutive patients(55 males and 40 females; total mean age: 53 year old) with cardiac tamponade or impending cardiac tamponade were enrolled in this study. The puncture site for pericardiocentesis, as determined by echocardiography, was the subcostal area in 43 patients(45%), the apical area in 40 patients(42%), the left parasternal area In 11 patients(12%), and the right parastemal area in one patient(1%). Pericardiocentesis failed in 2 patients(2%) with the subcostal approach and in one patient(1%) with the apical approach. The average epicardium-to-pericardium distance was 31 ±21 mm in patients with the subcostal approach and 21±8 mm in patients with other approaches. There were no differences in the amount of pericardial fluid and in the intraperical pressure among patient groups according to puncture site. There were two procedure related complications: a puncture of the right ventricle with the subcostal approach and a ventricular tachycardia with the apical approach.

본 연구는 휠체어농구선수와 장애가 없이 휠체어농구를 하는 선수 간 심리기술 및 자기관리의 수준과 심리기술이 자기관리에 미치는 영향력을 알아보고자 하는데 목적이 있다. 본 연구는 2008년 현재 대한장애인농구협회에 등록된 모든 선수를 대상으로 실시하였으며, 응답이 부실한 설문지를 제외한 총 106명의 설문지를 대상으로 자료를 분석하였다. 설문에 응답한 106명 중 휠체어농구선수 집단은 59명, 장애가 없는 휠체어농구선수 집단은 47명이었다. 본 연구의 조사도구는 유진(1996)의 운동선수 심리기술 검사지와 허정훈(2003)의 운동선수 자기관리 검사지를 사용하였다. 조사도구에 대한 타당성 검증은 탐색적 요인분석을 실시하였고 신뢰도 검증은 Cronbach's α를 실시하였다. 조사한 자료의 분석은 two-way ANOVA, Multiple Regression analysis를 실시하였으며, 유의수준은 α<.05로 설정하였다. 자료 분석 결과, 첫째, 장애유무와 포지션에 따른 심리기술에서는, 휠체어농구선수집단이 집중력과 불안조절에서 장애가 없는 휠체어농구선수 집단보다 높은 수준을 나타냈다. 둘째, 장애유무와 경력에 따른 심리기술 중 목표설정과 심상에서 경력이 짧은 집단은 장애가 없는 휠체어농구선수집단이 높은 수준을 나타냈고, 그와 반대로 경력이 오래된 집단에서는 휠체어농구선수집단이 높은 수준을 나타냈다. 또한, 경력 4-6년 집단이 목표설정과 심상에서 제일 높은 수준을 나타냈다. 셋째, 선수들의 심리기술이 자기관리에 미치는 영향에서는 몸관리에서 목표설정과 팀조화가 영향을 미쳤고, 대인관리에서는 팀조화, 심상, 의지력이 영향을 미쳤으며, 훈련관리에서는 의지력, 심상, 목표설정, 팀조화가 영향을 미치는 것으로 나타났다. 이에 따라, 경기력 향상을 위해서는 휠체어농구 선수들에게 체력훈련과 기술훈련 외에 심리훈련을 병행 실시해야 할 것이다. The purpose of this study was to examine the level and relative influence of the psychological skills and self-management of wheelchair basketball athletes and able-bodied wheelchair basketball athletes. The subjects in this study were carried with every athlete who registered with the Korea Wheelchair Basketball Federation. After a survey was conducted, the answer sheets from 106 participants were analyzed except for incomplete ones. Out of the 106 respondents, 59 persons were WA group, and 47 persons were AWA group. The instruments used in this study were Yu Jin's Athlete Psychological Skills Inventory and Heo Jeong-hun (2002)'s Athlete Self-Management Inventory. To verify the validity of the instruments, an exploratory factor analysis was carried out, and Cronbach alpha coefficient was utilized to test their reliability. For data analysis, two-way ANOVA, one-way ANOVA and multiple regression analysis were employed, and the level of significance was set at α<.05. As a result of data analysis, First, as for the relationship of the presence or absence of disabilities and position to psychological skills, the WA group was ahead of the AWA group in concentration and anxiety-control. Second, concerning the relationship of disabilities and career to psychological skills, the less-experienced athletes of the AWA group excelled their counterparts of the WA group at goal-setting and imagery, which were two of psychological skills. In the event of the experienced athletes, however, the WA group surpassed the AWA group in those regards. The athletes who had served as athletes for four to six years were most excellent in goal-setting and imagery. Third, the grade of skills made no difference to their level of psychological skills and self-management. Fourth, as to the impact of psychological skills on self-management, their healthcare was under the influence of goal-setting and teamwork; and teamwork, imagery and will-power had an impact on interpersonal skills. Training-management was affected by will-power, imagery, goal-setting and teamwork. Consequently, in aim to advance the athletic performance, it should co-apply psychological practice for the wheelchair basketball players in accordance with physical training and technical skill.
