The objective of this study was to examine the effects of mother's perfectionism and parenting beliefs on her preschooler's social competence. The participants were 277 mothers residing in Daejeon, Korea. Basic descriptive statistics, Cronbach's ${\alpha}$, t-test, ANOVA, and multiple regression were used for statistical treatment. The results were as follows: First, a mother's perfectionism and parenting beliefs did not differ according to her educational level. One factor of perfectionism, 'holding high standards', alone showed significant difference between highschool graduates and graduate school graduates, the latter's scores being higher than the former's. There were no significant differences in preschooler's social competence by sex or age. However, a few sex and age differences were found in sub-factors of social competence. Girls scored higher than boys on 'showing affection', and 5 year olds scored lower on 'showing affection' and higher on 'leadership' than 3 years olds. Second, a mother's perfectionism and parenting beliefs were able to explain 22.8% of variance in preschooler's social competence, the former showing more predictive power than the latter. Each of the two factors of maternal perfectionism affected five factors of preschooler's social competence in a different manner. 'Holding high standards' of perfectionism positively influenced preschooler's social competence factors such as 'social capability', 'leadership', and 'showing affection', whereas maternal 'fear of failure' had a negative impact on 'showing affection', 'disturbing'(reversed), and 'instability'(reversed). These results were discussed in relation with changes in social atmosphere and value systems, changes in child-rearing behaviors, or the construct and concept of perfectionism itself, It was suggested that these results be utilized in developing parent education programs for preschoolers lacking social competence.

The main studying problem of this study is to develop the scale which examines awareness of singleness for Korean men and women. So, firstly, study 1 fulfilled open survey related to condition for solitary life, its strengths and weaknesses and factors disturbing it for 490 unmarried and married people (244 men and 246 women) who are living in Seoul and capital area. And then, content analysis and category analysis were analyzed for their responses. As the result, each questionnaire was divided into economic aspect, relative aspect, characteristic aspect, eco related aspect, family aspect and social system aspect. Study 2 organized questionnaires for condition for solitary life, its strengths and weaknesses based on the material obtained in study 1 and then, exploratory factor analysis was conducted for total 800 adults (400 men and 400 women) who are living in Seoul, capital area, Incheon and Chungnam. As the result, the condition for solitary life extracted 5 factors including ego-maturity factor (24 questionnaires, total explanation quantity: 61.7%), strengths of solitary life extracted 6 factors including self-growth factor(29 questionnaires, total explanation quantity: 61.4 %) and weaknesses of solitary life extracted 6 factors including solitary factor(31questionnaires, total explanation quantity: 64.75 %). For verifying the suitability of the factor structure, as the result of conducting confirmatory factor analysis for 400 people (200 men and 200 women), the suitability of awareness scale model of men and women on singleness was verified. Those results were discussed from the aspect of variables and phenomenon related to singleness and marriage of Korean society.

Purpose : Cerebrovascular disease is the most frequent cause of death in Korea and it remains severe disabilities disturbing normal life, According to the previous studies, mortality of the stroke in the first one week is up to the 20% and 95% of stroke patients in the acute stage are accompanied by more than one complications. These complications affect not only the acute stage mortality but also the late stage rehabilitations. In Korea the oriental medicine is preformed in the treatment of stroke. Therefore it is important to recognize thoroughly the complications in the acute stage of stroke and to prevent them. But studies about complications of acute stage stroke is rarely presented in the fields of oriental medicine. So this study is prepared for investigating the characteristics and frequency of complications in the acute stage of stroke. And we are to assess the importance of theses acute complications by systemic reviewing the previous studies. Methods : Fifty one patients are included who had been admitted to ICU(intensive care unit) of Chenju Hospital of Wonkwang Oriental Medicine. Twenty nine patients are diagnosed as ischemic stroke and twenty one patients are diagnosed hemorrhagic stroke. Medical and neurological complications were investigated retrospectively based on medical notes excluding primary symptoms of stroke Le. motor weakness, sensory disturbance and speech disorder. And risk factors of stroke such as D.M. or hypertension are excluded. Results : Medical complications are more frequent than neurological ones. Most frequent medical complication is dysuria(61%) and constipation(45%), fever(30%) and aspiration pneumonia(22%) are followed in order of frequency. In Neurological complication dysphagia(56%), the exacerbation of infarction due to increased intracranial pressure(24%), irritability or insomnia(21%) is most frequently complicated in order of frequency. Conclusions : These complications are mostly caused by bed rest state in acute stage stroke. It is supposed that more aggressive management can prevent theses ones. And it is possible to improve the medical and neurological conditions by sticking theses study results.

Gas hydrates are ice-like crystalline compounds that form under low temperature and elevated pressure conditions. Recently, gas hydrates present a novel means for natural gas storage and transportation with potential applications in a wide variety of areas. An important property of hydrates that makes them attractive for use in gas storage and transportation is their very high gas-to-sol id ratio. In addition to the high gas content, gas hydrates are remarkably stable. The main barrier to development of gas hydrate technology is the lack of an effective mass production method of gas hydrate in solid form. In this study, some performance comparison among several cases classified by different volume sizes of solution were carried to identify the characteristics due to the volume increment. And it is found that one of the main reasons disturbing hydrate formation is related to the lack of cooling heat transfer due to the volume increase of the solution. So, three kinds of heat transfer plates which have different shapes and cross sectional areas were made and tested for the performance comparison following to the shape and area of each plate. Finally it is clarified that the heat transfer is one of the major factors effecting hydrate formation performance and the installation of heat transfer plate can enhance the formation performance especially not in terms of the quantity but the speed.

Background: Sleep-related disturbances and sleep disorders are common in Parkinson's disease (PD) and have a great impact on daily life of PD patients. This study was done to find the sleep characteristics and sleep disturbing factors in PD patients according to disease severity through clinical interview and polysomnographic (PSG) study. Methods: Fifty patients with PD (22 males, age $60.6{\pm}6.4$, Hoehn and Yahr (HY) stage $2.7{\pm}1.0$) were recruited and thoroughly interviewed about their sleep. PSG was performed on the patients taking routine antiparkinsonian medications. Patients were grouped into mild and moderate/severe group according to HY stage, and the results were compared between each group. Results: Ninety-four percent of total patients had one or more sleep-related disturbances based on the interview or PSG. On interview, the moderate/severe group complained more insomnia and REM sleep behavior disorder (RBD) than mild group. In PSG findings, the moderate/severe group showed lower sleep efficiency, longer sleep latency, REM sleep latency, waking time after sleep onset, and higher prevalence of RBD. Conclusions: In this study, most patients with PD had sleep disturbances. Clinical interview and PSG findings revealed deterioration of sleep quality along the disease severity. Our results suggest that sleep disturbances in PD patients are prevalent and warrant clinical attention, especially to the patients with advanced disease.

Pain is one of the most frequent and disturbing symptom of cancer patients. And almost of cancer patients are afraid of a attacks of pain related to cancer. Caring for the cancer patient can be divided into two phases. The phase of "active treatment" involves various interventions-surgical, chemical or radiological- that are designed to prolong the patient's life. "Terminal care" is the period from the end of active treatment until the patient's death. But in the majority of clinical settings, cancer pain is not being managed adequately results from a lack of education about how to treat the cancer pain management in the safest and most effective way during terminal phase. Althought organic factors represent the most important cause of their pain, it is also important to deal with the patient's psychological reactions and to take account of his or her social and family environment if treatment for chronic cancer pain is to prove adequate. Thus we try to evaluate a kinds of cancer related to pain, degree of pain, effectiveness of drugs, and patient's responses to management. In regard to the satisfaction for pain relief in pain clinics at Pusan National University Hospital(PNUH) are about 70% in patients and 90% in family. Average life expectancy in cancer patients are about 140 days (3 days- 5.7 years). Cancer patients are complained of several discomfortness (above 30 kinds) such as, pain associated with cancer (75%), nausea and vomitting (38%), sleeping disorder (38%), anorexia (38%), dyspnea (32%), constipation (31%), etc. Distributions of cancer associated with pain are stomach cancer (21%), lung cancer (16%), cervix cancer (10%), anorectal and colon cancer (8.6%), hepatoma (8%), pancreatic cancer (3%). About 1/3 of patients are suffer from incident pain in 3~5 times in a day especially in moving, coughing, and exercise. Methods for drug delivering system before death are transdermal fentanyl patch (42%), intravenous PCA (21%), oral intake of opioid (17%), epidural PCA (14%), etc.

Inorganic matters originated from stone quarries and manufacturing plants could alter the ecological characteristics of adjacent aquatic systems, especially the structure and function of benthic macroinvertebrate community. In such situation, the locality of stone quarry and the quantity of inorganic matters would be important factors that determined the disturbing strength to the benthic macroinvertebrate community. Locality patterns of stone quarries were classified into 3 types in relation to the stream ecosystem; stream-proximity, upstream-inclusion and tributary-inclusion type. In the result of species:abundance analysis, stone quarry B (upstream-inclusion type) showed geometric distribution, while others showed broken-stick distribution pattern. The benthic macroinvertebrate communities closer to stone quarries showed smaller species numbers and standing crops among all types of stone quarries. However the values of species evenness index were not seriously different between controls and directly affected sites. These results indicated that the effect of inorganic disturbance would differ from those of organic pollution that induced the highly dominant state occupied by tolerant species. Number of occurred species, standing crops, community indices and biotic indices indicated that the community of upstream-inclusion type was the most seriously damaged from the inorganic disturbance, and the community would be very simple and unstable. Tributary-inclusion stone quarry heavily damaged to tributary system in biologically, but influence to the main stream seemed to be depended on the scale of main stream. Among 3 types of stone quarry localities, stream-proximity type induced the least damages to benthic macroinvertebrate community, though the degrees of damage were different along with distances between stream and stone quarry.

Purpose: The purpose of this study was to identify relationships between quality of sleep, symptom cluster, depression, environmental disorder, and quality of life among hospitalized cancer patients. Methods: The subjects were 114 patients who underwent chemotherapy for colon cancer, gastric cancer, gynecologic cancer and breast cancer. They were recruited from the cancer center of a university hospital. Data were collected from August 4th to 30th, 2011. The questionnaires included the Korean sleep scale A (quality of sleep), MDASI-K (symptom cluster), the environmental sleep disturbing scale, Zung's depression scale, and the Korean version of EORTC QLQ-C30. The collected data was analyzed by t-test, ANOVA, multiple regression analysis using the SPSS 19.0 program. Results: Functional QOL was negatively associated with symptom QOL (r=-.798, p<.001). Symptom cluster, depression, & spouse (46.3%) were the most powerful predictors for functional QOL (46.3%) and symptom QOL (53.4%). Conclusion: It is evident that oncology nurses need to evaluate two dimensions of quality of life for cancer patients, for example, functional and symptom QOL. We recommend nurses develop specific protocols for relieving physical symptoms and alleviating depression, and furthermore test the effectiveness of them.

Purpose: The purpose of this study was to analyze teaching status and knowledge about children with Attention Deficit Hyperactivity Disorder (ADHD) in elementary school teachers. Methods: The participants of this study were 204 elementary school teachers in Busan. From July to September 2010, the researchers collected data by using self-report questionnaires consisted of questions about their teachers' characteristics and teaching status and KADDS (36 items) developed by Sciutto, Terjesen and Frank. Frequency, percentage, arithmetic mean, standard deviation, t-test and ANOVA were used to analyze the data using SPSS WIN 16.0 program. Results: Less than 50% of the participants had previous education on ADHD. According to this experience, there were significant differences in participants' knowledge about children with ADHD (t=4.703, p<.001). For the 36 items, participants had an average of $19.19{\pm}4.58$ points out of a possible 36. Moreover, lack of knowledge about teaching children with ADHD and communication problems with the parents of these children were considered to be the most disturbing factors. Conclusion: These results suggest that networks among teachers, parents and medical care professionals should be established. The results also indicate that educational programs for elementary school teachers should be developed in order to identify and teach children with ADHD appropriately.

Excessive input of organic matters from fish cage farming has been considered as one of the major factors disturbing benthic ecosystem, especially in semi-enclosed coastal waters. Recently offshore aquaculture in the vicinity of Jeju-do has been introduced to minimize that kind of negative impact. This study was conducted to investigate the ecological impacts of offshore aquaculture on the macrobenthic polychaete communities. A total of ten sampling works were carried out for 28 months, spanning from 10 days after starting giving feed to 3 months after stopping giving feed. During the study period, mean current velocity was quite strong with the range of 50 cm/s to 70 cm/s. TOC of surface sediment was constantly low. Significant changes in polychaete community were detected just three months after starting giving feed, which were the increase of the number of species and density at all stations. Up to 18 months after the start of farming, the amount of feed provided played an important role in the fluctuation of the number of species and density, especially at 0 m and 10 m stations. After reducing the amount of feed provided, dominance of some opportunistic species within 10 m distance from fish cages still lasted to the end of aquaculture. However, opportunistic species disappeared 3 months after the end of farming, which indicated the sign of recovery from the disturbance. From these results, the amount of food input and the period of cultivation were critical factors disturbing polychaete community and ensuing changes in this offshore and oligotrophic waters as well. In addition, study on the changes of polychaete community structure before and after fish farming showed more detailed changes in benthic ecological state than geochemical approach did.
