The role of scintigraphic imaging has moved from the detection of lesions to the tissue-specific characterization of lesions over the past 2 decades. Major advances in nuclear medicine imaging include: 1) positron imaging, 2) improved instrumentation, such as the use of multidetector (dual or triple head) gamma cameras for single photon emission computed tomography, and 3) development of numerous new radiopharmaceuticals for positron or single photon imaging ( labeled glucose analogue, amino acids, fatty acids, hormones, drugs, receptor ligands, monoclonal antibodies, etc). These advanced have resulted in a significantly improved efficacy of radionuclide techniques for the evaluation of various of focal gepatic tumors is reviewed in this article with an emphasis on the clinical applications of various tracer studies and imaging findings.

PURPOSE: This is a qualitative study to identify dimensions of long-term care hospital care quality that provide high-level medical services for long-term care patients in Korea. METHODS: Service consumers and providers were interviewed, and collected data were analyzed into thesis, type and dimension. The focus group method was applied to two provider groups and individual interview was applied to two persons who had experienced a long-term care hospital. RESULTS: The results of analyzing the comsumers and providers was integrated into 8 dimensions: physical environment, staff, clinical care and nursing, multiplicity of activity program, atmosphere, interaction with family, nutrition, and quality improvement system. CONCLUSION: The dimensions of long-term care hospital care quality from this study can be used as a basis of quality indicators. Quantitative studies to test these dimensions are required for establishing quality management systems.

The purpose of this study is to assess dietary habits of the hazardous drinkers and the heavy episodic drinkers in Korean adults. The respondents consisted of 814 adults (415 male and 399 female) who are 20~69 years of age by random selection in partial area of Gyeonggi. A self-report questionnaire was used to cover questions regarding dietary habits, drinking behavior and physical activity. Total dietary habit scores in hazardous drinker group (63.25) was significantly lower than normal drinker group (68.61) in male respondents (P<0.001). Male hazardous drinker group less eat fruit (P<0.01), eat more processed food (P<0.01) than male normal drinker group. Female hazardous drinker group doesn't eat 3 meals a day than female normal drinker group. Total dietary habit scores in heavy episodic drinker group [occasional heavy episodic drinker (62.76), frequent heavy episodic drinker (63.77)] were significantly lower than abstainer group (69.16) in male respondents (P<0.001). Male heavy episodic drinker group less eat fruit (P<0.01), eats more processed food (P<0.01), salty food (P<0.001), sugary food (P<0.05), animal fat (P<0.01) and eats out often (P<0.01) than male abstainer group. Male heavy episodic drinker group significantly less apply nutrition knowledge to their life (P<0.05) and less exercise everyday-more than 1 hour (P<0.01) than male abstainer group. In drinking behavior index, AUDIT (alcohol use disorder identification test) score was negatively correlated with age (P<0.01). There was a positive correlation between dietary habits and physical activity (P<0.01) but there was negative correlation between dietary habits and AUDIT score (P<0.01). This study highlights that AUDIT score was negatively influenced dietary habits.

Adequate vitamin B2, vitamin B6, folate and vitamin B12 intakes are known to be important for the growth and development in infants. The purpose of this study was to evaluate concentrations of vitamin B2, vitamin B6, folate and vitamin B12 in human milk and to investigate the relationship between vitamin B levels in human milk and dietary habits and other health-related behaviors. Milk samples were obtained from 38 healthy lactating women (aged 29.0 +/- 3.2 years) who are participating in the cohort study on pregnant women. Vitamin B2 concentrations in human milk were positively correlated with maternal vitamin B2 intakes in lactating mothers. Vitamin B6, folate and vitamin B12 concentrations in human milk were not correlated with maternal B vitamin intakes. Vitamin B6 concentrations in human milk were negatively correlated with the amount of postpartum weight loss. The vitamin B concentrations in human milk were not associated with maternal age, height, weight and parity. Mothers who were exposed to indirect smoking had lower vitamin B2 concentrations, and those who reported to consume health foods had higher vitamin B2 concentrations in their milk. In conclusion, lactating women need to consume more vitamin B intakes for the growth and development in infants. Further researches are needed to find other diet and health-related factors which influence on B vitamin concentrations in human milk.

PURPOSE: This study was carried out to accumulate basic data for nursing intervention development by evaluating the stress and emotional status of patients and their families after receiving hematopoietic stem cell transplantation (HSCT), illucidating and analysing related factors in order to decrease the negative effects of HSCT on their emotion. METHODS: Data were collected using a questionnaire to 53 HSCT patients and 50 families, who were older than 18 at tertiary-care institutions in Seoul, from January, 2000 to August, 2003. RESULTS: There was a significant score difference in stress (t=-2.302, p<0.05). Correlation between stress and emotional status was statistically significant (r=0.486, p<0.01; r=0, p<0.05). Economical burden of cost had significant effects on stress of patients (F=4.194, p<0.05). The series of emotional status of patients without jobs were higher (T=-2.583, p<0.05). The emotional status of families were influenced by monthly income (F=4.036, p<0.05) and patients' diagnosis (F=3.088, p<0.05). CONCLUSION: These results suggest that the cares for families should be considered with great concern as well as the ones for patients. In addition, such factors as economical burden by medical cost, monthly income and job status should not be excluded in transplantation nursing plans.

By using (99m)Tc-Pertechnetate, we evaluated the thyroid function of 136 persons with uptake slopeindex(U.S.I.) which was calculated by computerized dynamic flow study. Also, we compared our results of U.S.I.with those of established ¹³¹I-24 hr uptake % in given materials by comparative analysis of their correlation with the hormonal values of T3, T4, Free T4. The results wre as follows: 1. The U.S.I. of euthyroidismal group and hyperthyrodismal group were 4.87±2.26, 27.67±9.56 respectively. The ¹³¹I-24 hr uptake % of above groups were29.22±10.23, and 71.45±15.51. So the differentiation of the two groups could be done more easily by using (99m)Tc-Pertenchnetate U.S.I. than by using ¹³¹I-24 hr uptake %. 2. The correlation rates between (99m)Tc-Pertechnetate U.S.I. and other laboratory hormon levels, T3, T4, Free T4, ar almost parallel with thosebetweeen ¹³¹I-24 hr uptake % and the values of T3, T4, Free T4. Also the direct correlation rate between (99m)Tc-Pertechnetate U.S.I. and ¹³¹I-24 hr uptake % was 0.898. So, the method of thyroidal function evaluation by (99m)Tc-Pettechnetate U.S.I. is very reliable. 3. The (99m)Tc-Pertechnetate U.S.I. is very helpful to evaulate thefunctions of each lobe respectively incases of having obviously different radioactivity between both lobes. 4. (99m)Tc-Pertechnetate used dynamic thyroid function study and scan can be performed during the short time without preparation and especially helpful in debilitating patient and patients under antithyroid drug therapy, who need repetitive follow-up examination.
