Objectives : Insomnia may be one of the risk factor for suicidal ideation, but little is known about the mechanism by which sleep disturbances confer risk for suicide. The aim of this study was to investigate examine whether insomnia severity would be associated with resilience and suicidal ideation, and whether resilience would mediate the relationship between insomnia and suicidal ideation. Methods : A total of 432 community-dwelling adults(227 male, 205 female,) completed the self-report questionnaire that covered basic socio-demographic data. To assess the psychological variables, the following instruments were applied: Insomnia Severity Index(ISI), Korean Version of the Connor-Davidson Resilience Scale(K-CD-RISC), Beck Hopelessness Scale(BHOP) and Scale for Suicidal Ideation(SSI-Beck). People with an ISI score of 8 or higher were defined as insomnia. Results : Greater insomnia symptom severity was significantly associated with higher level of suicidal ideation and lower level of resilience, adjusting for hopelessness, age, sex, presence of family members living together, and household income. Additional analysis revealed that disturbance of sleep initiation and disturbance of sleep maintenance were significantly associated with suicidal ideation. Mediation analyses revealed that resilience significantly accounted for the relationship between insomnia symptom severity and suicidal ideation. Conclusions : These findings suggest that the evaluation and control of insomnia and resilience may be needed to reduce the risk of suicide.

Regular activity program is needed for managing chronic disease and obesity and preventing falls as a nursing intervention. It seems that serious game will be very important for older people to keep them active with fun to improve their health. This study was conducted to explore the correlations between health problems and computer game needs in the elderly. This was a cross-sectional study. A questionnaire was developed and administered to a convenience sample of adults who are older than 55 years, recruited from several places through trained research assistants and research center that has online pools in Korea. 778 subjects (mean age: $61.4\;{\pm}\;5.6$) were participated in this study. The majority of subjects was male (68.6%). We found that there was higher needs for exercise or serious game in the group of ma1e(55.4%), below undergraduate(66.2%), under two family members(32.5%), over 350,000 won of pocket money/month (40.1%), mild depressive symptom (51.7%), and online responser(68%). Especially, they wanted to overcome physical limitations through games. Higher education, more experiences and skills of using computer/internet was statistically and positively significant to the needs for exercise or serious game. In conclusion, there exists a potential market within this demographic group for the use of serious games. Thus, we need to develop senior games in Korean to improve quality of life and health promotion.

The purpose of this study is to examine the effect of the quality of performance on audience satisfaction, and to verify the mediating effect of service value and traditional image in this process. The subjects of this study included 211 male and female adults who experienced the Korean opera performance in Seoul, Korea in October. Collected data was used as a model of path coefficients obtained through analysis of covariance structure and hypothesis test. As a result of verification, program quality, physical environment quality, and quality of the stage performance perceived by the audience showed a statistically significant positive correlation with performance experience attributes. The path coefficient between performance attribute and service value, performance experience attribute and traditional image were also positively and statistically significant. Further, the path coefficient between performance experience and audience satisfaction showed a positive relationship. The service value and traditional image, service value and audience satisfaction, and the path coefficient between traditional image and audience satisfaction were statistically and positively significant. Finally, all hypotheses were adopted and study results confirmed the effect of service quality and experience attributes on audience satisfaction for the popularization, modernization and marketing strategy of the Korean opera. In this process, it is meaningful to verify the role and function of service value and traditional image.

Objective: To analyze clinicopathological characteristics, prognostic factors and survival rates of the patients with urological soft tissue sarcomas treated and followed up in Turkey. Materials and Methods: For overall survival analyses the Kaplan-Meier method was used. From medical records, nine prognostic factors on overall survival were analysed. Results: For the 53 patients (34 males, 19 females) whose charts were reviewed, the median age was 53 (range 22 to 83) years. Most frequently renal location (n=30; 56.6%) was evident and leiomyosarcoma (n=20, 37.7%) was the most frequently encountered histological type. Median survival time of all patients was 40.3 (95% CI, 14.2-66.3) months. In univariate analysis, male gender, advanced age (${\geq}50years$), metastatic stage, unresectability, grade 3, renal location were determined as worse prognostic factors. In multivariate analysis, metastatic stage, unresectability and grade 3 were determined as indicators of worse prognosis. Conclusions: Urological soft tissue sarcomas are rarely seen tumours in adults. The most important factors in survival are surgical resection, stage of the tumour at onset, grade and location of the tumour, gender and age of the patients.

The present study aimed to find the most sensitive placement of the skull to perceive speech through the bone vibrator in various protection methods while being exposed to noise. Twenty young normal-hearing adults (10 male and 10 female) participated in the study. As stimulus, Korean spondee words were presented via one of five skull locations (i.e., jaw angle, condyle, temple, mastoid, and vertex), while the participants wore one of four protection methods (i.e., ear form, ear plug, ear muff, and ear form and muff together) against white noise in one of four noise directions (i.e., 0, 90, 180, 270 degrees). The results showed: 1) there was a significant difference among the five skull locations with condyle being the most sensitive placement; 2) there was a significant difference among the four protection methods, with the ear form plus ear muff condition (or dual protection) providing the lowest threshold; 3) when exposed to noise from 90 degrees, the significantly lowest threshold was found; 4) there was no significant difference in results by gender. The pattern of results suggests that the communicative condition via the condyle bone conduction and the dual protection of the air conduction under any noise direction might be ideal for preventing noise-induced hearing loss, although further studies should be undertaken in this area.

Background: Improvement of lumbo-pelvic stability can reduce the compensatory action of the quadratus lumborum (QL) and selectively strengthen the gluteus medius (GM) during side-lying hip abduction (SHA). There are abdominal draw-in maneuver (ADIM) and abdominal bracing (AB) as active ways, and pelvic compression belt (PCB) as a passive way to increase of lumbo-pelvic stability. It is necessary to compare how these stabilization methods affect the selective strengthening of the GM. Objects: To investigate the effects of ADIM, AB, and PCB during SHA on the electromyography (EMG) activity of the GM, QL, external oblique (EO) and internal oblique (IO), and the GM/QL EMG activity ratio. Methods: A total of 20 healthy male adults participated in the study. The subjects performed three conditions in side-lying in random order: SHA with ADIM (SHA-ADIM), SHA with AB (SHA-AB), and SHA with PCB (SHA-PCB). To compare the differences among the three conditions, the EMG activities of the GM, QL, EO and IO, and GM/QL EMG activity ratio were analyzed using one-way repeated ANOVA. Results: The EMG activity of the QL was significantly higher in SHA-AB than in SHA-ADIM and SHA-PCB. The GM/QL activity ratio was significantly higher in SHA-PCB than in SHA-ADIM and SHA-AB. In addition, the figure for SHA-ADIM was significantly higher than that for SHA-AB. In the case of the EO, the figure for SHA-AB was significantly higher than corresponding values for the other two conditions. The figure for SHA-ADIM was significantly higher than that for SHA-PCB. The EMG activity of the IO was significantly higher in SHA-AH than in SHA-PCB. Conclusion: It can be suggested that wearing the PCB can more selectively strengthen the GM than to perform ADIM and AB during SHA. In addition, the ADIM can be recommended when there is a need to strengthen abdominal muscles during SHA.

The purpose of this study was undertaken to determine the effects of orthognathic surgery on speech. The hyposis stated herein is that functional behaviors of the dentofacial complex, such as speech production, may be adversely affected by deviations of a structural nature(especially, Class III malocclusion). Twenty adults with Class III malocclusion(13 female and 7 male) were studied preoperative, immediate postoperative and either 6 or 12 months postoperative lateral cephalograms. They had mandibular prognathism and had undergone mandible setback operation. The position of tongue, soft palate(Uvula), hyoid bone, respiratory track width, and pharyngeal depth were assessed on lateral cephalograms with 23 cephalometric variables, ANOVA, Paired t-tests and Pearson's product-moment correlation coefficient tests were used to evalute the operative changes in all cephalometric parameters. A experienced speech and language pathologists performed narrow phonetic transcriptions of tape-recorded words and sentences produced by each of the ninth patients and the recording tapes were analyzed by phonetic computer program(Computerized Speech Lab(CSL) Model 4300BI(U.S.A.)) These judges also recorded their ratings of each patient's overall consonants, hypernasality, hyponasality, and articulation proficiency. The results obtained are as follows; 1. There were significant changes in distance of posterior pharyngeal wall to tongue (TI-TW2, TS-TW3) after the surgery at 6 months postoperatively(each p<0.01 p<0.05). 2. The posterior tongue point(TI, TS, PPT) moved posteriorly after surgery and remained to its changed position at 6 months postoperatively(p<0.05). The displacement of tongue was correlated with the movement of mandibular setback amount(p<0.05). The hyoid bone moved posteriorly superiorly after immediate postoperative period. There was significant changes in hyoid bone movement after immediated postoperative period(p<0.05), but returned to its original position during the follow-up period(p>0.05) 3. The soft palate was displaced posteriorly superiorly after immediated operative period and remained to its changed position at 6 months postoperatively(p<0.05). ANS-PNS-SPT angle increasing, PPU-PPPo distance narrowing was showed after surgery, and remained its appearance 6 months postoperatively(p<0.05). 4. There were significant changes in formant value and squre diagram of vowel sound after the orthognathic surgery and the follow-up period. There were significant changes in /ㅅ/sound and posterior tongue sound. 5. The posterior movement of tongue and the posteriosuperior movement of soft palate was correlated with mandibular setback amount after orthognathic surgery. On the vowel squre diagram, the author found that the place of articulation after operation moved downward, backward, upward. 6. In assessing speech abnormalities, dental occlusion should be considered as a contributing factor. The vast majority of subjects with preoperative misarticulations eliminated or reduced their errors following orthognathic surgery. There was significant difference in speech impovement between pre- and postoperation.

Progressive transformation of germinal centers (PTGC) is mostly a disease of young adults and it presents as unexplained, asymptomatic, localized or generalized lymphadenopathy that is usually persistent or recurrent over a period of many years. PTGCs are larger than regular germinal centers and they contain a variable proportion of small mantle zone lymphocytes and so they become progressively transformed and they may result in the loss of clear demarcation between them and the mantle zone. PTGC may resemble the nodules of nodular lymphocyte predominant Hodgkin's disease (NLPHD) and it may be mistaken for NLPHD. Histological and immunohistochemical studies are helpful in differentiating these diseases. Because of the relatively frequent recurrences of PTGC, follow-up and repeat biopsy are indicated. Although PTGC is not considered to be a premalignant condition, PTGC may occur prior to, concurrent with or following NLPHD. This emphasizes the need for ongoing follow-up and repeat biopsy. Although PTGC is reported in 3.5% to 10% of the cases of chronic nonspecific lymphadenopathy, oral & maxillofacial surgeons are not widely aware of this condition and its clinical implications. Herein, we present a case of PTGC. A 24-year-old male without any history of immunodeficiency or autoimmune disease was admitted to the Department of Oral & Maxillofacial surgery at Ulsan University Hospital for evaluation of a right submandibular swelling. He had another mass on the right thigh that was noticed about 1 year ago. The submandibular lesion was completely resected and biopsied. The histological findings and immunohistochemical stains (CD3, CD15, CD20, CD30, CD57, BCL-2, EMA) were consistent with PTGC. He was followed up without any other complaints for 9 months.

The purpose of this study is to observe the effects of ice-pack application on different body areas and to note which body area produces the best results according to age, room temperature, sex and disease. Seventeen patients, including six men and eleven women, hospitalized at Seoul National University Hospital from May 22 to August 29, 1971, ranging in age from 15 through 60 years with an oral temperature of 38℃ or over, were chosen for this study. They were observed with regard to the effect of the ice-packs after applications for 30, 45 or 60 minutes. Four ice-packs, 7.6inch by 9 inch, were applied on the chest and the abdominal surface in the control group and the same size and number of packs on the axillae and political regions in the experimental group. The study results were reviewed in a statistical method to obtain the following findings 1. There was no significant difference in the change of the body temperature between the control group and the experimental group after applying the packs for 30, 45 or 60 minutes. 2. Individually, there was a significant difference in the change of body temperature between before and after application for 30, 45 or 60 minutes. 3. The difference of room temperature also had no merle influence on the body temperature taken immediately before applying the ice-packs. Even when ice-packs were applied for 30, 45 or 60 minutes, the room temperature did not influence the reduction of temperature in the patient. 4. There was a significant difference in the change of the body temperature, according to the sex, after application for 30, 45 or 60 minutes. Male patient's body temperature decreased far more noticeably than the female patients and the degree of reduction became more pronounced the longer the packs were applied. 5. In regard to age, in adults, the degree of reduction in the body temperature by the application of ice-packs was similar after appling them for 30, 45 or 60 minutes and did not depend upon the length of application. 6. Regardless of the disease, there was no great difference in the reduction of body temperature when the ice-packs were applied for 30 or 45 minutes, except for patients with typhoid fever when a striking decrease in the fever resulted after a 60 minute application of the ice-pack.

This descriptive study was under taken to explore relationships among the quality of life, health locus of control and perceived state of health persons with cancer to contribute theoretical understanding about these phenomenon of interest to the quality of nursing care. The subjects of this were 200 persons with cancer (100- in patients and 100- out patients), both male and female, between 30 and 59 years of age. Data were obtained using a convenience sample technique from two university hospitals in seoul from August, 1989, to June, 1990. The instruments used for this study were the Quality of life scale developed by Ro, You - Ja and the Health Locus of Control scale developed by Wallston & Wallston. Data were analyzed using a SAS program for ANOVA, t-test, Schefffe test, Pearson Correlation Coefficients and Stepwise multiple regression. The results were as follows : 1. The scores on the quality of life scale ranged from 95 to 191 with as mean of 147.85(range 47 to 235). The Mean scores(range 1-5) on the different dimensions were family relationships 3.50, relationships with neighbours 3.48, self - esteem 3.17, physical state and function 2.99, economic life 2.93 and emotional life 2.91. 2. Significantly higher scores on the quality of life and demographic characteristics were as follows : the quality of life for women(t＝2.80, p＝ .006), for those without complications(t＝2.54, p＝ .013), and for those who perceived their illness as mild(F＝4.85, p＝ .009). Higher scores on quality of life were correlated with the following : 1) emotional state and the age group 50-59(F＝3.43, p＝ .34). 2) economic life and higher income(F＝6.72, p＝ .002), those without complications(t＝2.68, p＝ .00), and those who perceived their illness as mild(F＝3.11, p＝ .05). 3) self-esteem and marriage(F＝3.64, p＝.028), those without complications(t＝2.18, p＝.03), and those who perceived their illness as mild(F＝7.72, p＝.000). 4) physical state and funciton and the age group 30-39(F＝4.65, p＝.010), those without complications (t＝2.00, p＝.05), and those who perceived their illness as mild(F＝3.38, p＝.04). 5) family relationship and those who live with their spouse(t＝2.82, p＝.005). 3. There was a significant positive correlation between the subjects perceptions of their current state of health and the quality of life score(r＝.4364, p＝.0001). 4. There was no relationship between Locus of control and quality of life in this sample. 5. Stepwise multiple regression analysis showed that: 1) the perception of current health status was the main predictor and accounted for 20.11% of the total variance. 2) sex and educational level accounted for an additional 21.71% of the total variance. 6. The quality of life and the perception of their current health status of these patients with cancer were generally lower than those of healthy adults as noted in previous studies. In conclusion, the quality of life for these cancer patients was generally low especially in regard to their emotional state. The current perceived state of health, sex, complications and perceived degree of illness were important variables relatiog to quality of life.
