Purpose - The purpose of this study is to clarify the mediating effect of profitability and activity in the relationship between productivity and stock return, assuming that the productivity of the company will affect share prices with the parameters of profitability and activity. Design/methodology/approach - The study extracted productivity indicators, profitability indicators, activity indicators, and share price-related indicators from 1999 to 2018 of non-financial enterprises listed on the securities market, and then classified them into three factors: productivity (labor productivity LP, capital productivity CP), activity (TT), and profitability (net profit rate NI, operating profit ratio OI) through the factor analysis method, and analyzed the impact of each factor on the stock return through steps 1 to 3. Findings - The regression analysis shows that productivity has a significant positive effect on the stock return through the full mediating effect of profitability and activity. Research implications or Originality - In a situation where the relationship between productivity and profitability is not clear, this study is meaningful in that it has empirically analyzed that productivity has a positive effect on the stock return by mediating effects of profitability and activity.

Zung’s self-Rating Depression scale (SDS) were applied to two hundreds & ten military high sh-cool students (MHSS) and 165 Non-military high school male students (NHSMS) in order to evaluate the quantitative and qualitative aspects of depression. Mean depression scores and score of various depressive items obtained from the each group were statistically analyzed. 1. The mean SDS scores were 43.90±8.36 for MHSS and 43.58±8.08 for NHSMS. (no signi-ficant differences) 2. The most frequent depressive signs found am-ong the all grades of MHSS were retardation, confusion, indecisiveness, and dissatisfaction, and decresed appetite were included for the second grade, and decreased appetite for the third grade, while retardation, decredsed lib-ido, confusion, and indecisiveness were the most frequent among NHSMS. 3. There was significant differences between the 1st grades of MHSS and NHSMS in pervasive affect (p<0.01). In each groups, 1st grades showed lower pervasive affect significantly (p<0.01) than the other two grades. The results suggested that the depressive trends of mili-tary high school students were within normal limits. And these conditions were considered as the effects due to especial interests of com-manding system and complete mental examin-ation as well as physical examination before entrance.
Rorschach 檢査에 依한 不安神經症 假神經症樣精神分裂症 및 妄相型精神分裂症의 比較硏究

When Rorschach gave us his test-his blots, his way of administering the experiment, as he called it, and interpreting the results he also left us a system of scoring the responses. Since Rorschach's death, other hands have worked to expand and perfect the scoring, but mostly this has meant increasing its differentiation and making explicit the criteria for assigning particular scores. Attempts to work out a theoretical rationale of the test, or to construct new scoring systems on a theoretical basis have been few indeed. Robert R. Holt and Joan Havel attempted to develop one of such supplementary methods, which they called as "A Method for Assessing Primary and Secondary Process in the Rorschach." In this paper the author has made a comparative study on anxiety neurosis, pseudoneurotic schizophrenia and paranoid schizophrenia according to the data of Rorschach results which were analyzed by the above mentioned robert R. Holt and Joan Havels' method. In the study the materials were comprised of 99 cases(32 males, 67 females) of anxiety neuroses, 42 cases (30 males, 12 females) of pseudo-neurotic schizophrenia and 40cases(26 males, 14 females) of paranoid schizophrenia, all of whom were seen and treated at the department of neuropsychiatry, Soo Do Medical College hospital during the period from August 1964 until July 1966. The results of the studies are as follows. 1. The mean of total Rorschach responses among the three groups were; anxiety neuroses, 19.8±8.51, pseudoneurotic schizophrenia, 23.9±12.42 and paranoid schizophrenia, 21.8±12.57. 2. The number and percentage of responses of ideational drive representations in the content variables among each group were; in anxiety neuroses, 374(18.9%) out of total 1977 responses 93(4.7%) of primary process thinking productions and 281(14.2%) of secondary process thinking productions, in pseudoneurotic schizophronia, 279(27.8%) out of total 1004 responses 150(14.9%) of primary process thinking productions and 129(12.9%) of secondary process thinking productions, in paranoid schizophrenia, 184(21.1%) out of total 872 responses 30(3.4%) of primary process thinking productions and 154)17.7%) of secondary process thinking productions. 3. The percentage of responses motivated by libidinal aims and aggressive aims among each groups were in anxiety neuroses, 37.2% of responses of libidinal aims and 37.4% of responses of aggressive aims, in pseudoneurotic schizophrenia, 63.8% of responses of libidinal aims and 23.8% of responses of aggressive aims and in paranoid schizophrenia 36.4% responses of libidinal aims and 42.4% of responses of aggressive aims. 4. In the formal variables the number and percentage of deviated structural responses among each groups were in anxiety neuroses, 219(11.1%) out of total 1977 responses which were subdivided into 105(5.3%) of primary process thinking productions and 114(5.8%) of secondary process thinking productions, in pseudoneurotic schizophrenia, 198(17.1%) out of total 1004 respenses which were subdivided into 124(10.8%) of primary process thinking productions and 74(6.3%) of secondary process thinking productions and in paranoid schizophrenia, 225(25.8%) out of total 872 responses which were subdivided into 129(14.8%) of primary process thinking productions and 96(11.0%) of secondary process thinking productions. 5. From these results the author might well suggest that the Robert R. Holt and Joan Havel's method for assessing primary and secondary process in the Rorschach would become a good tool not only for experimental studies but in clinical uses also.
