The purpose of this study was to find the effects of long-term combined exercise on regional bone mineral density(BMD) and cardiovascular disease(CVD) risk factors in the elderly with osteoporosis(OP). For the purpose, the subjects of this study were separated by two groups with thirty-one elderly women, who the first group was combined exercise group(CEG, n=16) and second group was non exercise group(CON, n=15). The combined exercise program was made up of warm-up (10min), work-out (aerobic; 30~45min/HRR 40~60%, resistance; 1RM * 50-70%, 8-10 * 2set ~ 10-15 * 1set), and cool-down (10min). Exercise group of the inspection have been trained 5 times a week for 1years. The results : At first, the variables of regional BMD were significantly different to pelvis, spine, trunk and T-score in two groups. At second, the variables of CVD risk factors were significantly different to SBP and DBP as well as TC, TG, LDL-C and HDL-C in two groups. As results of these conclusion, this study have positively effect shown that CEG was superior to CON in regional BMD(pelvis, spine, trunk and T-score), blood pressure(SBP, DBP) and plasma lipids(TC, TG, and LDL-C). Especially, the long-term combined exercise was provides a striking overall health quality of life with improving BMD and reduced CVD risk factors in the elderly with OP. In the future, other researches should deal with specific measures that reduction in mortality due to chronic disease and improvement quality of life for the development of programs in multiple researches of osteoporosis and chronic diseases.

The impact of a central place on daily living over wide outlying territory has been one of traditional subjects in the field of urban geography. The flow of rural population toward the central city of Chinju characterizes the population movement in Western Kyungnam, where the spillover of urban population into outlying areas, an especially prominent phenomenon in American society, does not occur. The central city of Chinju is supposed to be the most favored settlement area in Western Kyungnam. More than two thousands of teachers. who live in Chinju, cross the city boundary each morning to do their jobs in Western Kyungnam. But only ninety teachers living outside Chinju commute to the workplace in the city. The teachers willingly spend hours commuting each day to enjoy better quality of life in the central city. In fact, the central city of Chinju functions as bedroom communities for many middle-class workers in Western Kyungnam. On the basis of teachers' commuting behavior, four levels of Chinju's urban spheres are identified in Western Kyungnam. As Table-6 and Figure-2 show, the first-order level of Chinju's sphere includes most Myuns of Sanchung/Hadong Guns and some Myuns of Sachun/Gosung Guns. The second-order level comprises Sanchung/Sachun Eubs and many Myuns of Sachun /Gosung Guns. The third-order level is made up of Samchunpo, Hadong/Gosung/Eryung/Namhae/Habchun/Hamyang Eups, and many Myuns of Eryung/Namhae/Habchun Guns. And all of Guchang Gun and most Myuns of Hamyang Gun belong to the fourth-order level of Chinju's sphere. The influence sphere of Metropolitan Chinju is extended farther in the direction of less competition with other metropolises. Such a situation occurs to the west and south of Chinju. Daily commuting, defined as the journeys to and from work, is an excellent indicator for delimiting urban spheres of influence.

Human gastric adenocarcinomas are fixated with low energy of microwave (LEM) to study fixation effects in level of ultrastructure and antigenicity of the cancer. For the Ag-Ab reactions , the LEM fixated sdenocarcinomas are incorporated with monoclonal mouse anti-human p53 (IgG2b, kappa) and rabbit anti human cerbB-2. The retrieval of antigenicity are easily recognizable in the LEM fixated sections compared with that of frozen sections which show often diffused colour reactions. And the LEM fixation methods have preserved ultrastructures of the adenocarcinoma, but it was often difficult to maintain constancy in fixation effects. For the constancy, LEM was coupled with low concentration of chemical fixatives, such as glutaraldehyde (<1%) and $OsO_4$ (<0.5%). The results were acceptable, but there are tendencies that the adenocarcinoma requisitioned rather weak microwave energy to come into the optimal fixation effects. Therefore , cultured HeLa cells were fixated with lower energy of microwave than that used to the adenocarcinoma. The ultrastructures of the single HeLa cell have been preserved. The results may imply that a different energy levels of microwave are requisitioned in accordance with kinds of cells and tissues for the optimal fixation effects. It is reported and discussed that the fixation methods of LEM used in this work could be applied routinely to conceal a insufficient diffusion rate of chemical fixatives into some kinds of cancer without compromising the ultrastructures as well as to improve antigenic quality of frozen sections.

In order to improve the storage ability of Spur Red Delicious apple, calcium ingredients were applied to the apple tree during the growing period, and then the effects of calcium on appearances and respiratory activity of harvest apples were investigated during the storage period. The results of this work were summarized as follows: 1. The freshness of apples treated by calcium compounds reached $73{\sim}78%$, but that of control group was 68% by March of next year. 2. The respiratory rate of the apples that had been applied the high concentration of ammonium sulfate in field during the growing period, was accelerated rather than control group, and that of calcium treatment groups was continuously inhibited during the storage period. 3. The direct foliar application of calcium compounds in the field was more effective than dipping apples in calcium chloride solution for better quality and improving storage ability after harvest. 4. The freshness and hardness relatively not much decreased in calcium treatment groups even after 5 month storage.

Background: The impairment of the appearance is a major problem for patients with carcinomas of the oral cavity. These patients want to recover their preoperative facial appearance. Some do not realize that this is not always possible and hence develop a desire for further cosmetic and reconstructive surgery (CRS) which often causes psychological problems. Method: The desire of patients for CRS (N = 410; 26%) has been acquired in this $D{\ddot{O}}SAK$ rehab study including multiple reasons such as medical, functional, aesthetic and psychosocial aspects. They relate to the parameters of diagnosis, treatment and postoperative rehabilitation. Patients without the wish for CRS (N = 1155; 74%) served as control group. For the surgeons, knowledge of the patient's views is relevant in the wish for CRS. Nevertheless, it has hardly been investigated for patients postoperatively to complete resection of oral cancer. In this retrospective cross-sectional study, questionnaires with 147 variables were completed during control appointments. Thirty-eight departments of Oral and Maxillofacial Surgery took part, and 1652 German patients at least 6 months after complete cancer resection answered the questions. Additionally, a physician's questionnaire (N = 1489) was available. Statistical analysis was performed with SPSS vers. 22. Results: The patient's assessment of their appearance and scarring are the most important criteria resulting in wishes for CRS. Furthermore, functional limitations such as eating/swallowing, pain of the facial muscles, numb regions in the operating field, dealing with the social environment, return to work, tumour size and location, removal and reconstruction are closely related. Conclusion: The wish for CRS depends on diverse functional psychosocial and psychological parameters. Hence, it has to be issued during conversation to improve rehabilitation. A decision on the medical treatment can be of greater satisfaction if the surgeon knows the patients' needs and is able to compare them with the medical capabilities. The informed consent between doctor and patient in regard to these findings is necessary.

To estimate total burden of hospital admission over patient of gamily, we need to know the unofficial private expenses in addition to explicit hospital admission fees. This study was conducted from June 29, 2,000 to August 10, 2,000. Subjects were 104 patient at university hospital located at chungnam province. After thorough explanation of purpose and procedures, notebooks are given to each patient or guardian. They are requested to recorded all relevant expenditures occurred during hospital stay. Incomplete records were filled-up by direct personal contact or phones. Datas were summarized and analyzed using SAS statistical package. P-value less than 0.05 was considered significant. The results of the study are as follows: 1. In 96.1% of the patient, guardians stayed at hospital to take care of patients. In 38,8% one of the family members get work-leave or temporary resting from job. Average date of leave was 7.5days. 2. Average informal cost burden per patient was 204,467 won (14,330 won${\sim}$1,594,870 won). Average hospital cost paid by the patient was 1,061,807 won. The ratio of informal cost burden to hospital cost paid by the patient was 0.327. 3. According to the regression analysis, the relevant factors affection informal cost burdens were distance from home to hospital(p=0.018), and duration of hospitalization(p=0.0001). 4. Informal cost burden was composed of expenses for personal expense of care giver (126, 720 won/patient), meal (86,924 won/patient), transportation (77,648 won/patient), necessaries of life (18,789 won/patient), tests and treatments not covered by insurance (17,289 won/patient), medical supplies not covered by insurance (15,280 won/patient), treat for visitors (14,757 won/patient), TV coin (8,247 won/patient), and others (7,582 won/patient). In addition to the hospital cost paid by the patient for hospital admission, the informal cost burdens should be recognised explicitly because it is not small. Significant proportion of informal cost burden is composed of care-giver's personal expense, transportation, meal. It is suggested that some polices are to be devised and implemented enabling that this portion of informal expenses be directed to formal professional nursing care. Thus we can improve the quality of care and decrease discomfort of patient's relatives.

As the revitalization of the global maritime industry continues, the number of foreign ships navigating the maritime territories of maritime neighboring countries has rapidly increased. However, large-scale marine accidents have occurred, caused by the insufficient establishment of a system for management and operation relative to vessels' safety-condition. To address that, the IMO has granted the right to exercise port state control, especially for foreign vessels, to countries with jurisdiction over maritime territories with strengthening regulations and guidelines. In particular, the Republic of Korea, as a member of the TOKYO MOU, is conducting PSC, but as of 2020, the proportion of foreign ships was three times higher than that of national ships that called in domestic ports. However, the inspection rate was low at 9% which has not met the recommended level by the TOKYO MOU. Thus, this study conducted an IPA analysis as well as content analysis, by collecting the practical opinions and views of PSCO through objective questionnaires and written expert interviews, for improving the efficiency and effectiveness of domestic PSC. As a result, it was derived that the importance and performance related to human factors such as life on board, working environment, and response to safety accidents should be improved in to raise the quality of PSC inspection. Additionally, the work environment and performance of PSC in domestic ports for foreign vessels could be improved, if multifaceted support bases are established, for administrative unification of related tests for PSC, recruitment of PSCO, activation of the defection-reporting system, reorganization of the PSC execution group, etc.
