The purpose of this study is to provide basic data reflecting body characteristics for production of briefs by classifying lower body types of women in their 40s, 50s and 60s. The results are as follows: First, measurements for height-related items decreased while the measurements for width and depth items increased with age. However, 'hip width' and 'hip depth' items showed no significant differences among the age groups. In addition, no visible differences appeared in the length items among the age groups but 'waist to hip' and 'outside leg' lengths showed decreasing values according to age. Second, four factors were established from the factor analysis: 'obesity level around waist and abdomen', 'vertical length of the lower body', 'thickness and obesity level of lower limbs', and, 'size and shape of buttocks'. Lastly, cluster analysis resulted in the classification of the four factors mentioned above. Type 2 appeared the most, representing women in their 40s~60s. Type 1(n=257) was referred as 'slender with a short lower body', Type 2(n=443) as 'plump with short lower body', Type 3(n=224) as 'slender with long lower body', and Type 4(n=199) as 'obese around abdomen and lower limbs'.

This study analyzes on payment difference of users in sex, age, region using 23-months data by a university medical center to figure out factors which help to hospital management. The meaningful results of this study as follow. First of all, there is not statistically significant difference between men and women. Secondly, the researcher categorizes users under 40s into group A and 40s users into group B, those in 60s or older into group C. Then, researcher accepted H2 that there might be a difference on the age range of users in each group. Finally, In the results on difference analysis of the payment, there is only statistical difference between Busan and Ulsan Gyeongnam. These results is expected to provide basic information for efficient management of medical center.

This study tested customer preferences for "Fuji" apples stored using functional modified atmosphere film (30m) for 16 weeks at $0^{\circ}C$. Customers were 20-60 years of age and lived in either Seoul or Geochang. The freshness, texture, chewiness, and purchase attractiveness of apples in film packaging were judged to be significantly higher than control apples by those aged 20-29 years. The freshness, sourness, flavor, and purchase attractiveness of apples in film packaging were judged to be significantly higher than control apples by those aged 30-39 years. The flavor and sweetness of apples in film packag ing were judged to be significantly higher than control apples by those aged either 40-49 or 50-59 years (${\alpha}=0.05$). In the overall preference tests, apple freshness (P=0.0011), apple flavor (P=0.0002), and apple purchase attractiveness (P=0.0018) of apples in film packaging were judged to be significantly better than control apples by all age groups (those aged 20-59 years).

Metastatic bone tumor is the most common bone tumor and 32.5% of all primary malignant tumors are eventually metastasize to bone. Metastatic bone tumor has been more frequently encountered disease in the orthopedic fields due to the greater longevity of life of the patients with primary visceral cancers by major advances in early detection, diagnosis, and surgical/radiotherapeutic/chemotherapeutic treatment of primary and metastatic lesions. Therefore, the epidemiologic data about the incidences and the patterns of bone metastasis is important. We reviewed 417 patients who were diagnosed and treated for metastatic bone tumor at Kosin University Medical Center from 1985 to 1993 to analyse the primary lesion, age and sex distributions, location of bone metastasis, patterns of metastasis according to the primary. The results were as follows : 1. The common origin of bone metastasis were lung(29.5%), stomach(15.3%), breast(11.3%), unknown(7.7%), cervix(5.3%), liver(4.8%) in order of frequency. 2. There were 251 men and 166 women and their mean age was 54.8 years and the peak age incidence was in 6th decades. Most cases(85.3%) were occured beyond 5th decades. 3. The preferred sites of metastatic deposits were spine(64.0%), pelvis(40.5%), rib(38.8%), femur(36.7%), skull(21.1%), humerus(13.9%), scapula(13.0%) in order of frequency. In the spine, thoracic(42.1%), lumbar(39.1%), cervical(13.2%), sacral(5.6%) vertebrae were involved in order of frequency. 4. Multiple bone metastases were more common(73.1%) than single metastasis(26.9%). 5. In the lung cancer, the peak age incidence was 6th decades, and the preferred sites of bone metastasis were spine, pelvis, femur. 6. In the stomach cancer, the peak age incidence was 6th decades, and the preferred sites of bone metastasis were spine, femur, pelvis. 7. In the breast cancer, the peak age incidence was 5th decades, and the preferred sites of bone metastasis were spine, rib, pelvis. 8. In the bone metastasis with unknown primary site, the peak age incidence was 7th decades, the preferred sites of bone metastasis were spine, femur, pelvis, and the common histologic types were adenocarcinoma and squamous cell carcinoma.

This study focused on the effects of median type on drivers' subjective sense of speed and the changes in this sense by driver age. Participants were 61 drivers: 20 young (aged 20-39 years), 19 middle-aged (40-59 years), and 22 older drivers (60+ years). The participants watched each of two driving scenarios, showing either a guardrail-equipped or a concrete median. The participants were asked to push a button when they perceived speeds of 60 km/h, 80 km/h, or 100 km/h. All drivers perceived higher speeds in the guardrail condition than in the concrete condition. Perceived speeds increased with driver age in both guardrail and concrete conditions. These results mean median type affects drivers' subjective sense of speed even as driver age increases, and that drivers' subjective sense of speed tends to increase with age.

In this study three target radionuclides ($^{60}Co$, $^{137}Cs$, and $^{125}Sb$) were reacted with solid samples collected from the nuclear facility sites to investigate their sorption and mobility behaviors for preparing unexpected nuclear accidents. The highest sorption distribution coefficients ($K_{ds}$) of target radionuclides ($^{60}Co=947mL/g$, $^{137}Cs=2105mL/g$, $^{125}Sb=81.3mL/g$) were found in topsoil layer under groundwater condition, and the $K_d$ values of three radionuclides decreased in the order of fractured rock and bedrock samples under the same groundwater condition. High $K_d$ values of $^{60}Co$ in topsoil layer and fracture rock resulted from the clay minerals present, and the $K_d$ values decreased 58-69 % under seawater condition due to high ionic strength. $^{137}Cs$ sorption was controlled by the ion exchange reaction with $K^+$ on flayed edge sites (FES) of mica. The $^{137}Cs$ sorption was the most affected by seawater (89-97 % decrease), while $^{125}Sb$ sorption was not much affected by seawater. As the results of column and batch experiments, the retardation factors (R) of $^{137}Cs$, $^{60}Co$, and $^{125}Sb$ were determined about 5400-7400, 2000-2500, and 250-415, respectively, indicating no significant transport for these radionuclides even in fractured zone with groundwater. These results suggest that even in the case of severe nuclear accident at the nuclear facilities the mobility of released radionuclides ($^{60}Co$, $^{137}Cs$, and $^{125}Sb$) can be significantly retarded by the topsoil layer and fractured rock. In addition, the results of this study will be used for the safety and environmental performance assessment of nuclear facilities.

Purpose: In this study, we studied ocular disease by age in Ulsan. Methods: We checked medical record of 300 patients who visited eye clinic in Ulsan. Results: The main ocular disease on the age of 10 was keratitis, that of 20 was dry eye syndrome & keratitis, that of 30 was chalazion & conjunctivitis, that of 40~50 was conjunctivitis, that of 60 was conjunctivitis & cataract. Conclusions: The main cause of ocular disease of 10~20's are unsuitable wear of contact lenses & long-time use of smart phone as well as computer. That of 30~50's are allergic conjunctivitis and chemical material reaction as well as other several factors. Especially, attack rate of conjunctivitis of 30~50's is higher than city because of industrial area (Ulsan). The main cause of ocular disease in 50~60's is a kind of senility. Therefore, based on the results of this study, it could be used the basic data of education on ocular disease prevention in Ulsan.
