Purpose: The purpose of this study was to assess the efficacy and safety of radiofrequency ablation (RFA) to treat hepatic metastasis in patients with colorectal carcinoma. Materials and Methods: Between May 1999 and July 2002, a total of 45 tumors in 24 patients with colorectal cancer were treated with RFA. Thirteen patients received systemic chemotherapy after the RFA procedure. The ablation was performed percutaneously under ultrasound guidance using cool-tip or expandable electrodes and an RF generator. The medical records as well as the CT scan results taken every 3 months were retrospectively reviewed. Results: The median follow-up duration of the surviving patients was 11.7 months (4.6~32.2 months). Complete tumor necrosis was achieved in 17 patients (70.8%) on an immediate (〈24 hrs) CT scan. The median survival was 17.1 months. The 1- and 2-year survival rates were 80.5 and 25.8%, respectively. In a univariate analysis, complete necrosis, tumor size and post-RFA chemotherapy were significant factors for survival. Nineteen of the 24 patients developed a recurrence or progressed (79.2%). The median progression free survival was 5.5 months. There were no treatment related deaths or serious adverse effects, with the exception of one case of respiratory failure. Conclusion: These results suggest that RFA is a well-tolerated and effective method to treat hepatic metastasis in colorectal carcinomas.(Cancer Res Treat. 2004;36:128-131)

한국과 미국 성인자녀의 노부모와의 관계의 질과 부양행동 비교연구

최정혜(Choi, Jeong Hye) 한국노년학회 2009 한국노년학 Vol.29 No.2

The purpose of this study is to compare in the U.S. and Korea regarding adult children's quality of relationship and care provision for their elderly parents. The study sample consist of 320 adult children in the U.S. and 554 adult children in Korea with at least one parent living. The U.S. study sample is drawn from the State of California, and the Korean sample is drawn from Gyeongsangnamdo Province. The study result shows that the U.S adult children score higher than the Korean adult children in the quality of relationship measure for their elderly parents. And Korean adult children score higher than the U.S. adult children in the care provision measure for their elderly parents. It is found that the most significant factor influencing American adult children's care provision is caregiving attitude for elderly parents, while for Korean adult children, it is the quality of the relationship between adult children and elderly parents. This study results can serve as a foundation for understanding the U.S. and Korean differences regarding adult children's support for their elderly parents and for providing a solution to caregiving issues for elderly parents. 본 연구는 한국성인자녀와 미국성인자녀의 노부모와의 관계의 질과 부양행동을 비교하였다. 이를 통하여 한국과 미국 두 나라의 성인자녀와 노부모와의 관계 및 부양에 대한 문화적인 차이를 살펴보고, 나아가 우리나라 노부모 부양의 발전 방안모색에 유용한 자료를 제공하고자 한다. 연구대상자는 만 60세 이상의 노부모가 적어도 1명이상 살아있는 성인자녀로서, 미국 캘리포니아 주의 성인자녀 320명과 한국 경상남도의 성인자녀 554명 이다. 연구결과, 성인자녀의 노부모와의 관계의 질은 미국 성인자녀가 한국 성인자녀보다 더 높게 나타났으며, 성인자녀의 노부모 부양행동은 한국 성인자녀가 미국 성인자녀보다 더 높게 나타났다. 성인자녀의 노부모부양행동에 가장 영향을 미치는 변인은 미국은 노부모부양의식으로 나타났으며, 한국은 노부모와의 관계의 질로 나타나 나라간 차이를 보였다. 본 연구 결과를 통하여 노부모 부양행동에 있어서 미국의 경우 성인자녀의 노부모부양의식의 중요성을 알 수 있었고, 우리나라의 경우 성인자녀와 노부모의 세대 간 관계의 질이 중요함을 알 수 있었으므로 향후 우리나라의 노부모 부양정책 방안과 관련하여 성인자녀- 노부모 관계의 질을 강화할 수 있는 프로그램 모색이 필요하다하겠다.

User-generated contents (hereafter, UGC) are the contents produced by individual users. In addition to the conventional role of individuals as consumers, nowadays individuals can play an additional role as producers. Individual producers create their own virtual contents and share them with others, and some active producers try to communicate with their UGC users. As information technology advances and diffuses over space and time, this UGC-related market has grown substantially with the growing numbers of participants and the high quality contents. The popular UGC platform sites include: Youtube.com, Twitter.com, Facebook.com, and Wikipedia.com, which in fact belong to the top 10 Internet sites according to site traffic(Alexa Internet Inc., 2012). There has been much effort to understand the mechanism by which online performance is determined. Well-studied measures include product sales(Van den Bulte and Joshi, 2007; Dellarocas et al., 2007), sales ranks(Chevalier and Mayzlin, 2006), company profit(Liu, 2006; Chan et al., 2011). Key factors to derive online performance include product quality(Dichter, 1966), word-of-mouth among consumers(Liu, 2006), producers` particiation(Schwartz et al., 2011). For example, it is well known that product popularity has a positive influence on product sales(Kohler et al., 2011). Here, product popularity serves as a proxy for product quality and performance is measured using consumers` choices. UGC platformsites provide users opportunities to not only select but also engage by reviewing products and making recommendations, and this kind of behavior can reflect consumers` engagement(O`Hern et al., 2011; Schmitt et al., 2011). Thus, this research extends performance measures beyond choice-based ones and incorporate consumers` engagement-based measure. On the UGC platform sites, producers can easily observe communication among users, and some producers participate in consumers` conversation(O`Hern et al., 2011). Despite this growing producers` participation, there is limited research on its effect on performance. On the one hand, producers` communication with users can improve the relationship with users, which in turn increases users` interest and promote product choice(Doney and Cannon, 1997). On the other hand, producers` participation can inhibit consumers from speaking out(Kohler et al., 2011). Therefore it is needed to understand whether producers` participation improves or deteriorates UGC performance. This research collects data from Youtube.com in the category of `how to & style` using snowball sampling. On Youtube.com, users can view videos and leave comments, and also upload video clips. All the video-related and users` activities are collected and analyzed. The empirical analyses support all the proposed hypotheses. First, producers` participation has the positive impact on the choice-based performance and this positive effect strengthens with increasing product popularity. This means that when producers of popular products communicate with consumers, the choice-based performance improves(Kohler et al., 2011). On the contrary, producers` participation has the negative impact on the engagement-based performance and this negative effect gets stronger as products become more popular. This means that when producers of popular products participate in consumers` conversation, consumers are demotivated and do not express their opinion(Dellarocas et al., 2010). Producers` particition has the positive effect on consumer choice but the negative effect on consumer engagement. Therefore, in order to understand to what extent producers participate, both performance measures must be considered simultaneously. Further empirical investigation provides the following practical guidelines to decide on the level of producers` participation. First, producers of popular UGC should activily communicate with users. Avid participation by producers of popular UGC increases consumers` choices to the much greate

The purpose of this study is to investigate effects of Script Role Play on reducing problematic behaviors of elemental school children with school maladaptation. For the purpose, this researcher made the following hypotheses. First, the experimental group who participates in Script Role Play will show a statistically significant decrease in problematic behaviors than the control group who does not. Second, the experimental group who participates in Script Role Play will show a statistically significant increase in sociality quotient(SQ) than the control group who does not. To verify these hypotheses, the researcher surveyed 275 students in their 4th, 5th and 6th grades from H elementary school located in Busan. Out of the children, 38 whose score from School Maladaptation Test was 70% of full score or over(157 or over) were first selected. Out of the 38, then, 20 whose score from Problematic Behavior Test was 70% of full score or over(56 or over) were finally selected to be experimented here. The finally selected children were divided into experimental and control groups, each consisting of 10 members. The experimental group was asked to participate in total 14 sessions of Script Role Play. But the other group didn`t receive any treatment. Regarding measurement devices, School Maladaptation Test and Problematic Behavior Test were used to select children to be subjects. And Problematic Behavior Test and Social Maturity Test were used in the pre- and post-tests. Data were statistically processed using SPSS Program. The hypotheses made here were tested in the following ways. Homogenity between the experimental and control groups was analyzed through an independent-sample t-test of results of the pre-test(Problematic Behavior Test, Social Maturity Test). After the experiment, another independent-sample t-test of score difference between the pre- and post-tests was made to determine whether Script Role Play was effective in reducing problematic behaviors and improving sociality. Results of the study can be summarized as follows. First, the experimental and control groups were homogeneous to each other since there was no statistically significant difference between them. Second, in both the experimental and control groups, difference between scores from the pre- and post-tests was analyzed using t-test at the significance level of 0% to know how effective Script Role Play was in reducing problematic behaviors. As a result, it was found that in the experimental group, there was a significant difference between scores from the pre- and post-tests. Thus the program of Script Role Play had positive effects on reducing problematic behaviors by children with school maladaptation. Third, in both the experimental and control groups, difference between scores from athe pre- and post-tests was evaluated through t-test at the significance level of 5% to determine effects of Script Role Play on enhancing sociality. As a result, it was found that in both of the groups, score from the post-test was higher than that from the pre-test, but with no statistically significant difference. Thus the program of Script Role Play had no effect on the sociality quotient of children with school maladaptation. To make Script Role Play positively affect reduction in problematic behaviors by children with school maladaptation, it should be supported by school instruction that help those children`s better emotional development and behavioral formation. In addition, subsequent studies should be systematically made from the long-term view to make the play more helpful to improving those children`s sociality.

In January 2017, discolored black oat seeds were found in the storage depot of a farmhouse in Jeongeup. Pyrenophora sp. was detected in 45% of the oat seeds surveyed. All Pyrenophora isolates obtained from the seeds were identified as Pyrenophora avenae based on the sequences of internal transcribed spacer (ITS) rDNA regions and glyceraldehyde 3-phosphate dehydrogenase (GPDH) gene and validated by morphological and cultural characterization. A phylogenetic tree constructed using the ITS and GPDH sequences showed that the Korean isolates of P. avenae comprise of four genetically distinct groups. Pathogenicity test validated that the fungus is an infectious agent responsible for discolored black seeds and leaf blotch in oat plants. This is the first study report that P. avenae causes leaf blotch disease of oat in Korea.

Peanuts in storage were estimated for mycotoxigenic fungi and mycotoxins. Peanut samples collected from storages in Gochang were mainly contaminated with Fusarium (17.2±28.0%), Penicillium (12.4±28.0%), and Aspergillus (8.0±7.6%). Other genera, including Talaromyces, Rhizopus, Rhizoctonia, Trichocladium, Clonostachys, Mucor, Chaetomium, Trametes, Epicoccum, and Humicola, were also found. Although aflatoxins were not detected in the peanut samples, 29 strains of Aspergillus flavus were identified using molecular marker genes. Among them, 17 selected isolates produced aflatoxins in solid culture media ranging from 0.61-187.82 μg/kg. All of them could produce both aflatoxin B₁ and B₂ and some (n=5) produced additional G₁, G₂, or both. This study is the first report that A. flavus stains obtained from Korean stored peanut are aflatoxigenic.

최정혜(Choi, Jeong Hye) 한국노년학회 2000 한국노년학 Vol.20 No.3

본 연구는 최근 사회에서 관심의 영역으로 급증하고 있는 노인 문제 및 부부폭력문제와 관련하여 노인부부의 부부폭력에 있어서 성별로 어떠한 양상을 보이는지 그 실태를 파악함으로써 우리사회 노인부부폭력 문제의 해결방안을 위한 기초자료를 제공하고자 하였다. 본 연구자료는 경남지역에 거주하는 60세 이상의 남자노인 97명, 여자노인 257명으로 총 372명의 자료가 분석되었으며, SPSS WIN 7.5를 이용하여 통계처리 하였다. 분석결과 남자노인들이 배우자로부터 받는 부부폭력은 대부분 언어ㆍ상징적 폭력을 가장 많이 경험하고 있는 것으로 나타났으며, 여자노인들 역시 배우자로부터 받는 부부폭력은 대부분 언어ㆍ상징적 폭력으로 남자 노인과 같은 경향을 보여 주었다. 한편 남자노인들이 배우자로부터 경험한 신체적 폭력은 '주먹으로 맞았다'는 것이 가장 많았고, 여자노인들 역시 같은 경향으로 나타났으며, 경미한 신체적 폭력은 남자노인이 여자노인보다 더 많이 경험하는 경우도 있었으나 심각한 신체적 폭력은 모두 여자노인이 더 많이 경험한 것으로 나타났다. 성별에 따른 노인부부폭력에 대한 경험정도의 차이에 있어서는 여자노인이 남자노인보다 더 많이 경험하고 있는 것으로 나타났다. 또한 성별에 따른 노인부부폭력 경험은 사회ㆍ인구학적 변인에 따라 거의 차이가 나타나지 않았으며, 성장시의 부모폭력 경험 유무만 남녀노인 모두에게 영향변인으로 나타났다. 이상의 연구결과는 노인부부폭력 문제를 개선하고 삶의 질을 높이기 위해서는 노년기에도 지속적으로 부부가 서로를 존중할 수 있는 노인부부 재교육 프로그램의 필요성을 시사하며, 특히 성장시 부모폭력 경험 유무의 중요성을 감안하여 예방차원에서 이러한 면이 보완될 수 있는 교육적, 정책적 지원이 모색되어야 하겠다. The purposes of this study is to explore the conjugal violence of elderly couples in different sexes. The data are obtained through 372 men and women living in gyeongnam area whose ages are over 60.

최정혜(Jung Hye Choi),김태현(Tae Hyun Kim) 한국노년학회 1991 한국노년학 Vol.11 No.2

This research is written in light of the fact that under the present circumstance research on solidarity between aged parents and adult children is almost non-existent. This research intends to compare the city and country. The purpose of this research is to investigate the variables of the elderly problem and to provide useful suggestions on the direction of the establishment of policy relating to the elderly problem. In this research, a questionaire was used composed of a solidarity between aged and adult children index, a discord index, a self-respect index, and a self-control index. The subjects of the inquiry were elderly males and females over the aged of sixty who had one or more married children, and who lived in the rural or urban areas of Kyung Sang South Province. Finally, there were 450 questionaires used in the analysis : 225 in the city, and 225 in the country. The gathered materials were implemented using the SAS Program. The results are as follows : 1) 70.9% of aged parents felt that solidarity was on the low side when asked if their perception of solidarity with their adult children was below average. Also, 67.6% of aged parents felt that discord was on the high side when asked if their perception of discord with their adult children was above average. In addition, aged parents' discord with their adult children was higher in the country than in the city. 2) it was found that aged parents' perception of the variables exerting influence on solidarity with their adult children depended on the age of parents, economic level, type of dependence, gender, region of domicile, and existence or non-existence of spouse. 3) it was found that aged parents' perception of the variables exerting influence on discord with their adult children depended on educational level of parents, health, economic level, type of family, type of dependence, gender, and region of domicile. 4) the intermediary variables of self-respect and self-control were both found to be noticeable factors in aged parents' perception of solidarity and discord with their adult children. 5) it was found that type of family was the factor exerting the greatest power of influence on aged parents' perception of solidarity with their adult children. This was found to be the same both in the city and in the country. 6) it was found that aged parents' perception of solidarity with their adult children had a positive effect on the alleviation of aged parents' discord. 7) the results of the path analysis on aged parents perception of solidarity and discord with their children showed that the indirect path of the intermediary variable of the power. We see from the above results that in order to increase solidarity between aged parents and their adult children and to alleviate discord between them, rather than having a unilateral govermental policy of aged parents' dependence, a policy must be promulgated for elderly dependents which takes into account the differences in the actual situations found in rural and urban areas. In addition, the intermediary variables of self-respect and power of self-control are considerde to be important factors exerting influence on the alleviation of aged parents' discord.
