In this paper, we use panel dataset from Korean linked worker-firm to analyse the effects of the workforce age structure on the productivity or labor costs. We measure 'labor productivity' as added value per capita, 'cost of labor' as labor cost per capita and estimate a dynamic panel model to study the effects of the workforce age structure on the productivity or labor costs. Empirical analysis results show that the workforce age structure is positively related to productivity and labor costs, but only up to the aged of 35-39. That is, we find that an increase in the proportion of younger workers or elder workers rather than the aged 35-39 has a negative effect on productivity and labor cost. In particular, the difference between the estimation coefficient of productivity and labor cost when the share of workers aged 50 or older is increased instead of the aged 35-39 is higher than the difference between the estimation coefficient of productivity and labor cost when the share of workers aged 30 or younger is increased instead of the aged 35-39. Our results exhibit that it is reasonable for firms to worry about declining productivity of elderly workers, whereas firms already used older workers efficiently, such as by adjusting their labor costs.

The purpose of this study was to examine middle school students' (N= 153) perceptions of motivational climate (teacher learning/teacher comparison/peer learning/peer comparison/peer worry) and their achievement goals (task/performance/performance-avoidance). The influence of perceptions of motivational climate emphasized by science teachers and/or peers on achievement goals was explored by stepwise regression. Although there was no difference in male/female perceptions of motivational climate, there was significant difference in their achievement goals. Regression result indicated that the pursuit of learning by peers made the strongest contribution to students' task goal. On the other hand, promotion via comparison by science teachers or peers had little effect on inducing performance goal. Anxieties about mistakes were found to be the strongest contribution to predictions on students' performance-avoidance goal. The promotion of comparison by science teachers was related to not only performance goal, but also performance-avoidance goal. Lastly educational implications for intervention efforts designed to enhance the quality of student motivational development in science education are discussed.

The purposes of this study were to investigate the eating status and to analyze expenditures of the traditional fermented foods. A structured questionnaire survey was conducted from 370 housewives in Jeonbuk province and there were 300 usable samples(81.1%) valid for analysis. For the statistical analysis, the data was analyzed by $x^2$-test using SPSSIPC 12.0 for windows. The results of this study were as follows : 1. In the investigation on the eating status of the traditional fermented foods, Kimchi showed highest intake frequency(over once a day) and next Doenjang, Gochujang, Ganjang were consumed $2\;{\sim}\;3$ times per week. Jeotgal and Jangajji consumption showed the significant difference frequencies between the age groups(p < 0.001). The frequencies of using the home-made fermented foods were either similar or decreased, while the manufactured products were either similar or increased. The reasons behind the decreasing consumption were 'because of appetite change(47.0%)', 'the effect of western food(25.2%)' and 'dislike of salty food(17.4%)'. 90.7%(Kimchi), 54.9%(Doenjang), 54.8%(Gochujang), 53.2%(Cheongkukjang) of respondents knew the methods of preparation, while 62.5%(Ganjang), 41.1%(Jeotgal,) 31.2%(Jangajji) of respondents didn't know the methods of preparation. 2. In the analysis of the expenditure for the purchasing of the traditional fermented foods, most of the respondents procured Kimchi, Doenjang, Gochujang from their families or relatives, but they bought Ganjang, Jeotgal, Jangajji in the markets. And most of the respondents bought the fermented foods in the general merchandise stores or the department store except Kimchi. The places of buying Kimchi were specialty stores(34.6%), general merchandise stores or department stores(25.0%). Overall scores of satisfaction for the quality of manufactured fermented foods showed 3.29 of 5 - point scales. The average cost per month of Kimchi was 19,550won and Gochujang 7,878won, Doenjang 5,764won, Jeotgal 5,439won, Jangajji 5,412won, Ganjang(for soup) 4,714won, Cheongkukjang 4,677won, Ganjang(for seasoning) 4,464won, and total cost was 20,920won. The reasons behind purchasing the traditional fermented foods were 'because of convenience(58.4%)', 'no time to make by oneself(23.0%)' and 'for not knowing the making methods(12.8%)'. The problems of the manufactured traditional fermented foods were 'worry about safety of the raw materials or additives(71.2%)', 'lack of sanitation(12.0%)'. The most important thing considered in purchasing was 'materials and origins(86.6%)' and next 'quality(64.1%)' was another important thing.

With the rapid growth of Chinese economy, environmental issues also became a serious problem that public and private sector have to take under consideration. For the sustainable growth of Chinese economy scholars and policy makers agree to the stronger regulation for protection of natural environment, but at the same time worry about its negative effect on economic growth. This paper primarily focus on the relationship between the factors that have the effect on green product purchasing intention and purchasing behavior. Purchasing intention was considered as mediating variable in our model and state-action orientation - as moderating variable. We set 8 hypotheses and tested with structural equation modeling. The result shows that governmental regulation and subsidy, social environment related with green product purchase, and consumer perception on the benefit of green product have positive relationship with purchasing intention, but environmental concern does not show relationship with it. We also proved that state-action orientation has moderating effect between purchasing intention and purchasing behavior. Purchasing intention with action orientation show positive and statistically significant effect on purchasing behavior. This result supports the hypothesis that the attitude of customers has the effect on ones purchasing behavior.

As the hospitalized patients will be facing new stress situation due to change of his environment from home to hospital it will be very important to understand the psychological stress experienced by hospital patients not only for helping patients in the process of recovery from illness but also fulfil1ing the objective of comprehensive nursing care by understanding the needs of the patients. There is no doubt that it would be very helpful for treatment of patients as well as for improvement of nursing care if we know more about psychological needs of patients and give them adequate support to meet these needs. The study to find out the causes and degree of stress events experienced by hospitalized patients, with the objective of instituting improvement of nursing care program based on the needs of patients, was conducted during the month of September 1974 with 60 patients randomly selected from those admitted to medical and surgical wards at Yonsei Medical Center in that period The questionnaire form included 36 questions which are considered to be stress events for hospital patients, and was devide into five areas namely, such events related to 1) disease itself, 2) hospital environment, 3) nursing care and treatment, 4) communication and human relations, and 5) family and economic problems. The results of the study were as follows: 1. It was confirmed that hospitalization considered to be a stress producing factor and most patients perceived the admission to hospital as a stress factor. 2. According to the rating scale, it was found that degree of perceived stress shows a variation according to the source of stress producing event. 3. No significant differences in the mean values were observed statistically with the perceived stress levels according to demographic and other variables of patients related to hospitalization. 4. Among the questions related to disease itself, "Admission for surgery" was perceived most frequently as a stress event (97.14%) by patients. 5. With regard to the questions related to hospital environment, "death of the patient room-mate" was the most serious stress event perceived by patients (90%) and "living with hospital regulations"was considered to be less serious stress event (23.33%). 6. As for the questions related to nursing care and treatment, "limitation of freedom" was perceived as a stress factor most frequently (70.91%) by the patients and "worry for wrong treatment" turned out to be less frequent stress event (50.0%). 7. As for the questions related to communication and human relations, "difficulty to meet doctors when wanted"appeared to be the most frequent stress event by the respondents (75.86%) , followed by "no explanation about treatment or examination"(75.0%) and "no explanation about nursing care procedures"(71.66%). 8. With regard 111 tile questions related to family and economic problems, "inadequate finances for family living due to hospitalization"and "high cost of hospitalization" were the most frequent cause of stress mentioned by the patients. (80.0%). 9. As a result of application of the stepwise regression analysis, it was found that about 89% was explained by those events associated with disease itself, hospital environment and family and economic problems. By adding those events related to "nursing care and treatment" and "communication and human relation", 100% of stress associated with hospitalization was explained.

Because many of patients seeking orthodontic treatment worry about the facial appearance and their chief motivation for orthodontic treatment is facial esthetics, it is critical to understand the influence of gender or culture on the evaluation of profile esthetics. The purpose of this study was to find out any influence of gender or culture on judging good facial profile. 4 different groups were asked to evaluate 133 facial profiles to test the influence of gender or culture on judging good facial profiles. Those 4 groups consisted of 10 Korean males, 10 Korean females, 10 Korean American males, and 10 Korean American females. 2 evaluation systems were introduced, absolute and relative. Soft tissues of selected good profile group were analyzed and statistic analysis was performed. Conclusions were as follows 1. Inter-evaluator difference for judging good facial profile was statistically significant, even if there was general agreement for the best profile among 40 raters. 2. Gender difference under the same cultural environment was not significant statistically. 3. The same ethnic groups with different cultural background showed statistically different preference on judging good Profile. 4. Good facial profile group had their own characteristics compared to remaining group in several soft tissue measurements which were vertical facial ratio, soft tissue facial convexity, and antero-posterior relative lip position.

The purpose of this study was to examine the stressors and stress coping styles of 6th grade el ementary school children and to explore the relationship between stressful life events and health symptoms and the effects of coping style which is theoretically considered to mediate the relationship between stress and health symptoms. The study subjects consisted of 329 in 6th grade elementary school children in Cheong-Ju city. Of the 329 subjects, 171 were boys and 158 were girls. For this study, three kinds of questionnaires were adopted as follows ; 1) Feel Bad Scale (FBS) by Lewis et al., 2) lazarus-Folkman's Way of coping questionnaire 3) Hee Sun Shin's Health Symptom questionnaire (HSQ) The researcher visited the school and collected data in the class using the questionnaire method after an explanation of the purpose and procedures was given to the children. Data collection was done for 10 days (from 5th to 15th of July 1997) . The data were analyzed by descriptive statistics, correlation analysis, multiple regression analysis using the SAS statistical program. The results of this study were as follows : 1. The mean score for the FBS was 211.37(range : 77-427), The most severe stressors perceived by children were parental divorce and other's smash or steal of my things. The most frequently experienced stressful life events were conflict with siblings and being scolded for other's fault. 2. The most frequently used stress coping style was the active coping (M=17.85), followed by passive (M=13.64) and magical one (M=13.42). 3. The mean score for the HSQ was 23.30(range : 0-72) The most frequently complained health symptoms were headache and having much worry about everything. 4. There was a significant relationship between stressful life events and health symptoms (r=.60, p<.001). Also, stressful life events were positively related with passive coping(r=.27, p<.001) and magical coping (r=.38, p<.001). Health symptoms were positively correlated with passive coping(r=.33, p<.001) and magical coping (r=.41, p<.001). 5. Stepwise multiple regression analysis revealed that the most powerful predictor was the variable of stressful life events. Health concerns, magical coping style, passive coping style and active coping style accounted for 49.15% of the variance in health symptoms. This study revealed that stressful life events correlated with health symptoms in 6th grade elementary school children and passive coping and magical coping had mediating effects on this relationship. The implication for nursing is that there is a need to develop supportive interventions for high risk population to decrease health problems due to stress.

This study was undertaken to find out the causal perception of rheumatoid arthritis patients, and to understand the typology. The Q-population consisted of 236 statements of causal perception were collected. Thirty eight Q-samples of causal perception were selected. The P-sample for this study were made up of 28 first visiting female rheumatoid arthritis patients from a rheumatoid arthritis specialty hospital. Each respondent responded Q-set of causal perception according to 9-point scale. The result of Q-sorting were coded and analyzed using QUANL PC program. 1) Typological Observation on Causal Perception (1) Physical Fatigue Type : Type 1 perceived that the illness occurred due to excessive work requiring physical labor or strain that had occurred from not resting after excessive physical labor, therefore, thinking the origin of the illness was from physical strain. (2) Physical origin Type : Type 2 perceived that the major cause for the illness is not only excessive physical labour but also fecundity and old age. (3) Causality to Environment Type : Type 3 perceived that rheumatoid arthritis occurred from injury to the joints or bad and humid weather. (4) Conscience of Guilty Type : Type 4 consisted of people with guilty conscience for lack of religious commitment. They perceived that the illness was a punishment from God for not praying or because of bad luck. (5) Rationally Perceiving Type : People who belong in type 5 perceived the cause of illness in light of scientific facts such as genetics, unbalanced diet or lack of exercise. (6) Psychological Stress Type : People who belong in type 6 believed that excessive stress was the cause of the illness. 2) Emotions of Rheumatoid arthritis patients Rheumatoid arthritis patients' positive emotions included determination, courage, coping, acceptance, hope, and adoption ; and their negative emotions were prostration, worry, stupor, conflicts, grievance, giving-up, resignation, depression, loss, solitariness, fear, anxiety, avoidance, anger and loneliness. Rheumatoid arthritis patients experience different level of emotions from their suffering experience from the severe pains. Rheumatoid arthritis patients also experience negative emotions when they could not perform self-care and lose their self-esteem from painful suffering ; however, they regain positive emotions when they recover from pain with the use of drugs, physical therapy or exercise. Their emotional states are closely connected to level of and presence of pain.

Objectives The purpose of this study is to understand what caregivers think advantageous and disadvantageous regarding Acupoint sticking Dog-days. Also, to know whether Acupoint sticking in Dog-days affect vital signs, and to investigate if occurrence of side effects are related to application duration, sweat, or compliance to precautionary measures. Methods Survey has been handed out to parents of the children who took Acupoint sticking in Dog-days. 10 days after the first dose was administered, survey was performed to examine any side effect occurrences, characteristics of sweat, duration of application, parents' thought about this therapy. Also, vital signs were checked before the first dose, and 10 days after to see any differences in vital signs in regards to this therapy. Results Preferable opinions about Acupoint sticking in Dog-days are 'convenient than herbal medications' (76.5%), 'less reluctance of child' (47.1%), 'reasonable price' (20.6%), 'good effectiveness' (17.6%), 'less side effect' (14.7%), 'no worry about agrochemicals or heavy metals uptake' (11.8%). Downsides were 'difficult to admit to hospital right on the Dog-days' (73.5%), 'no conspicuous effectiveness' (11.8%), 'expensive' (5.9%), 'reluctance of child' (2.9%). Vital sign differences were minimal when examined before and after Acupoint sticking in Dog-days. Side effects occurred 5 times in 34 cases, and they were erythema, itchiness, and hot sensation. There were no scars or blisters reported. All 5 cases were resolved without any interventions within 3 days. Conclusions Acupoint sticking in Dog-days doesn't affect vital signs. Severe side effect is rare, reported side effects were relatively mild, suggesting that it may be safe and well-tolerated. 'Convenience' (76.5%) is biggest advantage of Acupoint sticking in Dog-days and 'less reluctance of child' is also big advantage of Acupoint sticking in Dog-days. 'Difficulty to admit to hospital right on the Dog-days' (73.5%) is biggest disadvantage of Acupoint sticking in Dog-days.

Objectives The objective of this study was to investigate the differences in sociodemographic and clinical characteristics, temperaments, and quality of life between panic disorder (PD) patients with and without major depressive disorder (PD+MDD and PD-MDD patients, respectively). Methods We compared 411 PD-MDD and 219 PD+MDD patients. All patients who were drug-free for at least 1 month were assessed at initial outpatient visits before the administration of medication. The following instruments were used for assessment: the NEO Personality Inventory-Neuroticism (NEO-N) ; the Temperament and Character Inventory-Harm Avoidance (TCI-HA) ; the State-Trait Anxiety Inventory (STAI) ; the Intolerance of Uncertainty Scale-Short (IUS); the Anxiety Sensitivity Index-Revised (ASI-R); the Beck Depression Inventory (BDI) ; the Beck Anxiety Inventory (BAI); the Penn State Worry Questionnaire (PSWQ) ; the Generalized Anxiety Disorder for 7 item (GAD-7) ; the Albany Panic and Phobia Questionnaire (APPQ) ; the Panic Disorder Severity Scale (PDSS) ; the Early Trauma Inventory Self Report-Short Form (ETISR-SF) ; the Scale for Suicidal Ideation (SSI) ; the World Health Organization Quality of Life Scale Abbreviated Version (WHOQOL-BREF) ; the Sheehan Disability Scale (SDS) ; and the Short Form health survey (SF-36). Results Compared to the PD-MDD patients, the PD+MDD patients were younger and more likely to be unmarried. They showed higher rates of unemployment, lower levels of education and income, younger age of onset, more previous suicide attempts, a greater incidence of agoraphobia, and more previous treatments. The PD+MDD patients showed significantly higher scores on the NEO-N, the TCI-HA, the STAI, the IUS, the ASI-R, the BDI, the BAI, the PSWQ, the GAD-7, the APPQ, the PDSS, the ETISR-SF, and the SSI. In addition, the PD+MDD patients showed significantly lower quality of life than did the PD-MDD patients. In contrast with previous studies, we observed no significant differences between the two groups in terms of gender, duration until treatment, and psychiatric comorbidities. Conclusions This study showed that the PD+MDD patients have more early trauma experiences, higher levels of anxiety-related temperaments, more severe panic and depressive symptoms, and lower quality of life than the PD-MDD patients.
