This study was performed to compare the transcultural differences on perimenstrual discomforts, menstrual attitudes and sex role acceptance between Korean and American college students. The subjects, 2557 nursing students were selected from 13 universities all around Korea, and 4 universities in the eastern, western, and middle areas of the United States. The data were collected using the MDQ (Menstrual Distress Questionnaire by Moos), the MAQ(Menstrual Attitude Questionnaire), and the Sex Role Acceptance Scale, the subjects answered the MDQ for three points (premenstrual, menstrual, intermenstrual based on their recollections) between July, 1996 and April, 1997. The findings are as follows : 1. There were significant differences in the age of menarche, duration of menstruation, and menstrual cycle between the Koreans and the Americans. 2. As for sex role acceptance, Americans more frequently denied the traditional female role than did Koreans. 3. There were significant differences between the two groups on five categories of menstrual attitude (menstruation is a phenomena that weakens women physically and psychologically, menstruation is a bothersome phenomena, menstruation is a natural phenomena, menstruation onset is a predictable phenomena, and menstruation is a phenomena that does not influence womens' behaviors non is expected to). 4. For the menstrual discomfort scores, there were significant differences between the two groups on all six categories of the MDQ(pain, attention deficit, behavioral changes, AMS response, water retention, and negative emotion) for the three points (premenstrual, menstrual, intermenstrual period). 5. The most common complaints for the Korean women were pain during the perimenstrual period and fatigue during the intermenstrual period. In contrast, for the Americans the most common complaint was negative emotions during the perimenstrual period, but less pain than the Koreans, and a similarity to Koreans during the intermenstrual period. 6. Regularity of the menstrual cycle was positively correlated with age of menarche, menstrual cycle, and duration of menstruation. 7 For the interrelationship between of Perimenstrual discomforts, menstrual attitudes, and sex role acceptance, there were significant correlations for both group as follows : First, the MA category "menstruation is a bothering phenomena" was negatively correlated with sex role acceptance, second, the MA category "menstruation is a phenomena that weakens the women physically and psychologically" was positively correlated with the MA category "menstruation onset is a predictable phenomena." For the further research, it is recommended that efficient nursing intervention programs for perimenstrual discomforts, be developed and qualitative research to demonstrate the cultural differences as the feminism view point be done.

Purpose - This study analyzes the effects of types of leadership on the employees of Italian restaurants, its efficacy, and organizational citizenship behavior, utilizing a causal assessment model. In this study, independent variables such as the type of leadership perceived in the manager or chef by an Italian restaurant's employees, and its efficacy were parameters, and the organizational citizenship behavior and organizational effectiveness were the variables representing the results in the hypothesis. The study aimed to draw implications by verifying the leadership via efficacy and the impact on organizational citizenship behavior of Italian restaurants. Research design, data, methodology - For the purpose of this analysis, specific questionnaire items were configured according to the theory and efficacy of the study. From a questionnaire used in organizational citizenship behavior comprising 22 questions, six were modified to suit the research purpose of this study. The configured questionnaire comprised 5 parts and 40 items. A Likert (Likert) 5-point scale was utilized to measure responses to the questionnaire items from the employees of an Italian restaurant in Seoul who participated in the survey. For data collection, 400 questionnaires were distributed, and 344 collected. Factor analysis and reliability verification were conducted using SPSS18.0 and AMOS18.0. A covariance structure analysis was conducted to test the research hypotheses. Results - Based on the results of the analyses, the summary and suggested implications of the research are as follows: The covariance structure analysis used to analyze the kind of effect transformational and transactional leadership styles in Italian restaurant employees had on self-efficacy, group-efficacy, and organizational citizenship behavior, indicated that among the characteristics of transformational leadership (such as, idealized influence, inspirational motivation, individual consideration, and intellectual stimulation), idealized influence and individual consideration had a positive influence on self-efficacy. Idealized influence, individual consideration, conditional reward, and management by exception also positively influenced self-efficacy and altruistic and conscientious behavior (organizational citizenship behavior). Conclusions - Results suggest that with regard to self-efficacy and group efficacy, managers in different departments and chefs should provide team members with a vision for the future, increase their confidence in their abilities, and build their trust in the organization. By evaluating employee performance and experiences, management can demonstrate leadership and encourage organizational citizenship behavior through enjoyable, voluntary participation. Transformational and transactional leadership is effective in group processes that include social-exchange relationships, self-efficacy and group efficacy, and organizational citizenship behavior. However, as this research study utilizes only self-reported data, it has several limitations, such as a vulnerability of errors caused by the various experiment types. A significant limitation of this study is the lack of potential for the duplication of results. The covariance structure analysis, however, provides complementation to limit the impact of errors from self-reporting studies. A future study can extend this research by utilizing different data collection methods.

This Study was done to design and test an instrument to measure the health status of the elderly including physical, psychologyical and social dimensions. Data collection was done from July 18 to August 17, 1990. Subjects were 412 older persons in Korea. A convenience sample was used but the place of residence was stratified into large, medium and small city and rural areas. Participants located in Sudaemun-Gu, Mapo-Gu, and Kangnam-Gu, Seoul were interviewed by brained nursing students, and those in Chungju, Jonju, Chuncheon, and Jinju by professors of nursing colleges. Rural residents were interviewed by community health practioners working in Kungsang-Buk-Do, Kyngsang- Nam - Bo, Jonla Buk -Do, and Kyung Ki- Do. The tool developed for this study was a structured questionnaire based on previous literature and then tested for reliability and validity. This tool contained 20 physical health status items, 17 mental-emotional health status items and 38 social health status items. Physical health status items clustered in to six factors such as personal hygiene, activity, home management, digestive, sexual, sensory, and climination functions. Mental-emotional health status items clustered into two factors, mental health and emotional health. Social health status items clustered into seven factors, grandparent, parent, spouse, friend, kinships, group member and religious role functions. Data analysis included percentage, average, S.D., t-test and ANOVA. The results of the analysis were as follows : 1. The tool measuring the health status of the elderly and developed for this research had a relatively high reliavility indicated by a cronbach＝0.97793. 2. Average score of the subjects physical health status was 4, 054 in a 5 point likert scale, mentalemotional health status was 3.803, social health status was 2.939 and the total average was 3.521. The social status of the subjects was the lowest and the next was mental-emotional health status ; physical health status was the highest. 3. Educational background, perceived health status, the amount of pocket money were related to physical and mental-emotional health status and family structure was related mental-emotional physical and social health status. Occupation was related to physical and mental-emotional status. Area of residence was related to metal-emotional and social status. Source of living in the expeneses was related to physical and mental-emotional health status marital status to mental-emotional and social health status, and the number living in the home physical health status and religion to social health status. The following conciusions were derived from the above results ; 1. The health status of Korean elderly was relatively sound but social health status was the most vulnerable. The Social activity for Korean elderly is needed to improve social health. 2. Educational background, perceived health status and the amount of pocket money must be considered in the health assessment criteria of the elderly, Family structure, marial status, occupation, residence variables and sources of living expense must also be considered as significant. 3. A health education program based on the educational background of the elderly, and provision of an occupational socioeconomic welfare policy will be useful in order to increase social health status of Korean elderly.

The purpose of this study were to identify the quality of life for the mothers of hospitalized chronic pediatric patients, and to explore the factors affecting the QOL of those mothers. The subjects were 201 mothers whose children had hospitalized at one University hospital with chronic diseases. Data were collected from the December, 1997 to December, 1998. We used a revised QOL instrument consisting of 34 items, 5 point likert scale based on the Noh's QOL instrument. The revised QOL consists of six subscales, those are physical status and function, self esteem, emotional status, economic status, relationship with family members, and relationship with neighborhood. Data were analyzed by t-test, ANOVA, Pearson's correlation using SPSS-PC. The results were as follows: 1. The mean score of quality of life for the mothers of chronic pediatric patients was 100.31, and item mean was 2.95. In subscale analysis, item mean of economic status was the lowest, and that of relationship with family members was the highest. 2. Correlations between characteristics of chronic pediatric patients, their mothers and QOL of mothers were as follows; 1) Total QOL of mothers had a significant positive relationship with progressing time relapse after diagnosing and age of mothers. There was a significant negative relationship between the total QOL of mothers and number of hospitalization of their children. 2) QOL on self esteem and economic status had a significant relationship with age of pediatric patients, the time relapse after diagnosis, and age of mothers. Total number of family members and QOL on economic status showed a significant positive relationship. QOL on emotional status, economic status, and relationship with family members of mothers showed negative correlations with the number of hospitalization of their children. 3. Followings were the result of difference in QOL among different demographic cha- racteristics of the subjects. 1) QOL on economic status of mothers was significantly higher when fathers of pediatric patients had jobs. 2) Total QOL score, QOL on emotional status, and QOL on relationship with neighborhood were significantly higher when mothers of pediatric patients had spouses. 3) QOL on self esteem of mothers was significantly higher when mothers had religion. 4. Followings were the result of difference in QOL among different diagnosis of the children. 1) Total QOL score of mothers whose children had congenital heart disease was higher than that of mothers whose children had leukemia and cancer. 2) QOL on emotional status, economic status, and relationship with family members of mothers whose children had congenital heart disease were higher than those of mothers whose children had leukemia, cancer, and epilepsy.

The purpose of this descriptive study was to identify the homecare needs of patients with cancer and to provide a basis of interventions. One hundred and two patients at one general hospital in Gyeongnam responded to a questionnaire developed on the basis of care needs perceived by nurses caring for hospitalized patients with cancer. The questionnaire was a Likert type 5 point scale with 56 items on five need categories ; 1) informational 2) physical care : 3) emotional care 4) socioeconomic care and 5) special care needs. Internal consistency of this questionnaire was Cronbach's $\alpha$＝.9101 for total items. The data was collected from March 1st to May 31th, 1998, by two graduate nurses. In the data analysis, mean & standard deviation were calculated to identify the degree of care need of each item, and the t-test & ANOVA were done to determine the effects of patients' demographic background on their care needs. The findings are summarized as follows ; 1) The mean score of total of need items was 3.048. Of the four need categories the highest score was informational at 3.4, followed by emotional care, 3.063, physical care, 2.623, and socioeconomic care, 2.599. 2) In the informational need category there were four subcategories with 19 items. Medication and pain control had the highest score, 3.755 ; second was diet and exercise, 3.613 ; third was disease and treatment process, 3.337 ; and last was personal hygiene and infection prevention at 2.687. 3) In the physical care need category there was nine items, IV infusion for nutrition and management of treatment complication was above 3.2 points and the remaining items were in the 2.847-2.070 score ranges. 4) In the emotional care need category there were seven items. The highest need was in support for relationships with health personnel, 3.673. The need for support of religions beliefs and support for having a religion were low at about 2 points. 5) In the socioeconomic care need category there were six items. Support for medical insurance expansion and financial support were above 3 points. Legal support and support for caring of children were low in the care needs. 6) In the special care need category the there were 15 items. Informational need about immunization and informational need about effects of disease on growth and development were high, above 4.1 points. Need for decubitus care and prevention, sitz bath and incontinence care were low, below 2 points. 7) There were significant differences in degree of care need according to admission rate, education level, marital status, religion and caregiver's religion. In conclusion, homecare needs perceived by hospitalized patient's with cancer was moderate, but informational need was higher than direct care need, leading to the conclusion that the provision of sufficient information to patients with cancer at discharge is needed. Nursing interventions should be developed considering the patient's background.

This research attempts to qualitatively evaluate the intensity change by radiopharmaceuticals and obtain computed tomography using phantom injected with various nuclide. Cylindrical phantom is used for comparing and analysing the effect on diagnosis image during radiopharmaceuticals inspection. Inside of the phantom, water is injected and computed tomography image is scanned. During nuclear medicine invitro, frequently used radiopharmaceuticals, $^{99m}TcO_4$ 20 mCi and $^{18}F$ 14 mCi, is diluted in the water phantom and scanned in the same method. Traverse image obtained by CT scan is divided into six traverse image in the same slice of each scanned image. CT-number(HU) value of 10 measuring point is measured in 2 cm interval based on the center of the phantom. Measured HU value, based on the water phantom, is compared with the image after injecting $^{99m}TcO_4$ and $^{18}F$. Average scale of water is 2.8~1.6 HU, $^{99m}TcO_4$ is 3.0~1.6 HU and $^{18}F$ is 1.2~0 HU. Average of water is $2.3{\pm}0.17$ HU, $^{99m}TcO_4$ is $2.2{\pm}0.85$ HU and F-18 is $0.7{\pm}0.95$ HU. Based on water, reduced value of about 0.1 HU and about 0.5 HU is acquired from $^{99m}TcO_4$ and F-18. Radionuclide used in nuclear medicine inspection utilizes 100~200 KeV energy and obtains image through scintillation camera and PET-CT utilizes 511 KeV positron annihilation energy to obtain image. What we learned from this research is that gamma rays from these energies used in CT scan for diagnosis purpose or radioactive therapy plan can change the intensity of the image. The nuclear medicine inspection for reducing the effect of emitted gamma ray diagnosis image should be obtained after a period of time considering half-life which would be reduced distortion or changed in image.

This study was conducted to suggest potential future directions in the effective operations of food safety information on the internet. This study consisted of two sections. The first section was a survey that was performed by 186 dieticians in Daegu and Gyeongbuk area. The second section was the assessment of the quality of food safety information on the internet. 163 web sites that provided food safety information on three major searching engines using the search words 'food safety' and 'HACCP' were investigated. The trained panels evaluated the contents of the web sites using a 3-point scale assessment tool. The data collected data from the questionnaires were statistically analyzed using the SPSS package program (version 14.0). The results of this analysis were as follow. The primary purpose of internet usage by detitians was to search for information (87.2%). In addition, the detitians' satisfaction degree of food safety information on the internet was 3.17 out of 5 points. The operators of web sites that were evaluated by the researchers were business and industries (76.1%), public organizations (15.3%), and individuals (8.8%). The following four items, update of content, offer scientific basis or explanation of content, offer useful information and new informations, should be improved immediately. Among evaluation items, six items were shown to be significantly different according to the operators of web sites. The evaluation scores of web sites that were operated by public organizations were significantly higher than those of web sites operated by individuals or business and industries. In conclusion, regular and consistent qualitative evaluation of web sites is needed to improve the quality of information that is provided via the internet. In addition, web sites that provided information on food safety should be actively operated by public organizations.
