Purpose: The purpose of this study is to identify the effect of the disease duration on depression change in cancer survivors between the middle and old age groups. Methodology: To that end, we analyzed 275 patients using the Korea welfare panel survey from 2011 to 2016 jointly developed by the Korea Institute for Health and Social Affairs and Seoul National University. The duration of the elapsed and the experienced was measured as a independent variable. CES-D was used as a dependent variable. Frequency, paired t-test, ANOVA, and logistic regression analysis were conducted using Stata 14.0 for statistical analysis. Findings: Studies have shown that as the duration of the elapsed and the experienced increases, people under 65 are 1.17 times and 1.84 times each more likely to be included in depression-increase group than in depression-reduction group. The group that has been maintaining economic activities continuously since 2011 was significantly less likely to belong to the depression-increase group than the group that did not have economic activities in 2016. For those aged 65 and older, there was no significant difference in the duration of the elapsed and the experienced. The higher the likelihood of low-income households being included in the family of depression was 2.58 times higher than for ordinary households. Practical Implications: It is suggested that close policy management of the employment and working environment of cancer survivors is necessary, as both cancer survivors of productive age as well as older cancer survivors are analyzed to be beneficial to depression management. In addition, a systematic management program related to the mental health of cancer survivors is believed to be necessary for normal social recovery in the future.

Pleural effusion means the inflammation of pleura which has a majority of respiratory disease. The main clinical manifestation is pleural effusional pain, dyspnea, cough, fever, etc. and at present the Tuberculous pleural effusion has the most frequency in which exists exudate in our country. And during studying oriental medical treatment about Tuberculous exudative pleural effusional patient, we found the clinical case about The Combination therapy of Chinese traditional and Western medicine at journal of traditional Chinese Medicine and considered it would be help in oriental medical treatment, so we adjust and report now. This study was performed by analyzing the six papers reported centering around the clinical case of The Combination therapy of Chinese traditional and Western medicine in journal of traditional Chinese Medicine published between 1990-1996. As these papers have no mistakes on diagnosis because it obtained pleurocentesis, tuberculin test positive reaction on choicing clinical case, definite results on X-ray, ultrasound as well as clinical basis, so it considers an apt conclusion. The results were as follows: 1. Western medical treatment uses chemical remedy same with pulmonary tuberculosis, and in case of tubercular pleuritis, it needs thoracic duct pyorrhea, and according to simple exudation also operates therapheutic pleural paracentesis. 2. In case of hydrothorax absorption about tuberculous pleural effusion, prescription of purge the heat accumulated in the lung and eliminate the retention of fluid with powerful purgatives shows considerable effects. 3. The latter period treatment of tuberculous pleural effusion needs Supplement qi and active the collaterals, Nourishing yin and clearing heat in addition to Supporting healthy energy to eliminate evils. 4. In case of curing tuberculous pleural effusion, The Combination therapy of Chinese traditional and Western medicine shows more considerable effect than single western medical treatment in absorption of hydrothorax. 5. In case of curing tuberculous pleural effusion, The Combination therapy of Chinese traditional and Western medicine shows more considerable effect than single western medical treatment in prevention of disease reappearance. 6. In case of curing tuberculous pleural effusion, The Combination therapy of Chinese traditional and Western medicine shows more considerable effect than single western medical treatment in vitality recovery at the latter period of disease.

This study was done to investigate stress and coping methods of mothers with brain disease children. The subjects for this study were obtained by taking a sample of mothers with brain disease children hospitalized in neurosurgery ward of K medical center in Seoul from Nov. 20, 1992 to Mar. 10, 1993. The collected date were analized by S.P.S.S. program(frequency, percentage, mean, t-test, ANOVA, Pearson Correlation). The results of the study were as follow. 1. The mean of the degree of mothers' stress was 3.681. Of the stress categories, illness treatment (4.216) was highest, and the next were in order of ill-ness status and prognosis(4.154) , family relation-ships and personal roles(3.202), interpersonal relationships(2.916). 2. The mean of the degree of mothers' coping method was 2.930. Of the coping method categories, communication with medical team or parents in similar situations(3.332) was highest, and the next were in or-der of family cooperation and optimistic thought about the situation(3.241), reforcement of self esteem and maintenance of psychological stability(2.538). 3. There was not seen a stastically significant correlation between stress factors and coping methods of mothers. But with categories, the higher the stress to illness status and prognosis was, the hight coping methods' degree of communication with medical team or parents in similar situations was shown a positive correlation, if not high (r=.2776, P=.046) . And the higher the stress to illness treatment was, the higher coping methods' degree of communication with medical team or parents in simial situations was shown a positive correlation, if not high (r=.2727, P=.049). 4. With the difference of stress according to mothers' general characteristics, religion and monthly income shew a statically significant difference. The mothers' group who have a religion shew the higher degree of stress(t=-3.17, P=.003), The group who get the most income shew highest degree of stress (F=.4693, P=.0156). With the difference of coping according to mothers' general characteristics, the most support-ing person, satisfaction with husbands and mothers' own health status shew a statistically significant difference. The group who get the most support from parents-in-law(F=3.7508, P=.013), the group who are much satisfied with husband(F=3.589, P=.016), and the group whose health status are good(F=3.3675, P=.046), shew the highest coping degree. 5. There were no significant difference in degree of stress and coping by children's characteristics The significance of the study will be concluded as follows. 1. Investigating the stress factors, which mothers are perceiving, it will be utilized as the basic materials of nursing plan so as to reduce the stress of mothers. 2. In searching for the ways of mothers' more helpful coping methods, it shows the necessity of the active nursing intervention for the mothers in the process of coping with their stress. That is, the nurse should serve the earnest nursing as counselor, supporter, educator, and information - provider. 3. Recogning mothers as well as children with brain disease as a client, the nurse will be able to help the mother, who is taking care of the children, cope with the stress situation well, and to make a contribution to the recovery, rehabilitation, and health of the children and to the enhancement of the family' health.

Physiological activity of osteoblast including bone formation is known to be closely related to the increase of intracellular $Ca^{2+}$ activity($[Ca^{2+}]_i$) in osteoblast. $Ca^{2+}$ is an important intracellular messenger in diverse cellular functions, and regulation of its level is mediated by the transmembrane $Ca^{2+}$ movement via $Ca^{2+}$ channels, $Na^+-Ca^{2+}$ exchange, and by intracellular $Ca^{2+}$ movement through the intracellular stores. The purpose of this study is to investigate how the intracellular $Ca^{2+}$ is regulated in osteoblast-like cells(OLCs) by measuring $Ca^{2+}$ activity with cell imaging technique. OLCs were isolated from femur and tibia of neonatal rats, and cultured for 7 days. Cultured OLCs were loaded with a $Ca^{2+}$-sensitive fluorescent dye, Fura-2, and fluorescence images were monitored with a cooled CCD camera. The images were processed and analyzed with an image analyzing software. The results were as follows. (1) $[Ca^{2+}]_i$ of OLC decreased as the $Ca^{2+}$ concentration in the superfusing Tyrode solution was lowered. When $Na^+$ concentration in the superfusing solution was decreased, $[Ca^{2+}]_i$ increased.. These suggest that $Ca^{2+}$ flux occurs via the $Na^+-Ca^{2+}$ exchange mechanism. (2) When $Na^+$ in the superfusing solution was removed. a transient $Ca^{2+}$, increase($Ca^{2+}$ spike) was occasionally observed. However, $Ca^{2+}$ spike was not observed after adding 1 ${\mu}M$ thapsigargin. This implies that the generation of $Ca^{2+}$ spike is mediated by the release of $Ca^{2+}$ from endoplasmic reticulum(ER). (3) As the $Ca^{2+}$ concentration in the superfusing solution was raised, the frequency of 0mM $Na^+$-induced $Ca^{2+}$ spike increased, suggesting that $Ca^{2+}$-induced $Ca^{2+}$ release(CICR) mechanism exists. (4) After $[Ca^{2+}]_i$ was decreased with the superfusion of $Ca^{2+}$-free solution containing thapsigargin, the recovery of $[Ca^{2+}]_i$ with reperfusion of 2.5mM $Ca^{2+}$ solution transiently exceeded the control level, suggesting that the depletion of $Ca^{2+}$ in ER induces $Ca^{2+}$ influx from extracellular medium via store-operated $Ca^{2+}$ influx(SOCI) mechanism. (5) $[Ca^{2+}]_i$ was not affected by the superfusion of 25mM $K^+$ Tyrode solution. These results suggest that intracellular $Ca^{2+}$ activity in osteoblast is regulated by transmembrane $Ca^{2+}$ flux via $Na^+-Ca^{2+}$ exchange, $Ca^{2+}$ release from the internal store (ER) via $Ca^{2+}$-induced $Ca^{2+}$ release, and store-operated $Ca^{2+}$ influx across the cell membrane.

Objectives: We did research in the cause of the Pitchers' injury and their recovery process to make a detailed injury list for the purpose of finding the cause of the Korean professional pitchers' injury and its classification. We drew the conclusion through the results as following. Methods: We posed a question to the 80 pitchers playing in the first team of the eight Korean professional baseball team and analyzed the 62 pieces of question paper except the paper having a mistake. We used SAS/PC statistical package in analyzing the data. Results: In the frequency of the pitchers' shoulder injury in the last three years, the injured of all the players were 61.3$\%$ and the injury free players were 28.7$\%$. The cause of the injury was 45.2$\%$ wrong pitching motion, which was the highest value. For the shape of a pain when injured, the reverberation ache feeling when he is hit in the weight commanded an absolute majority as 19.4$\%$. Those who had muscular pain were 17.7$\%$, which was felt mostly at the pitching motion. The most trouble name of the injured shoulder was bicepstendinitis as 16.1$\%$ while the injury of shoulder joint was the lowest as 1.6$\%$. As the most widely used treatment, 25.8 percent of all the players had taken an electronical thraphy after injury. 14.5 percent of the players who had an injury to the shoulder told that they have an operation and 85 percent of them didn't. As a sort of the operation, a repairing of labrum was 44.4 percent, which is the highest value and the 77.8 percent pitchers are performing a normal pitching through rehabilitation after the operation and 22.2 percent of them are undergoing rehabilitation training. Conclusion: The research have shown that the main cause of the injury, concerning the Korean professional pitchers throwing lots of ball in both matches and practices, is overuse syndrome, bad mechanism, muscle weakness and instability of balance. I think that the role of trainer, physical therapy, and team physician taking charge of the players' injury must learn physical test method by heart exactly to check up the state of the injury definitely at the initial phase. Moreover, when the cause of the injury part after a close examination is discovered, the scientific and good surgery is essential to the rehabilitation success and making a classification of shoulder instability is useful to make a operation plan as well as the players' rehabilitation, treatment.
