  • Background: This report determines the effects of a neurofeedback program on patients with breast cancer through a study of psychogenic factors(distress, depression, anxiety). Design: Randomized controlled trial. Methods: The study selected 28 patients with breast cancer and divided them into two groups: 14 subjects in the neurofeedback program group and 14 subjects in the exercise intervention program group. Both groups conducted one-and-hour training per session five times a week for a total of five weeks. The experimental group performed neurofeedback, and the control group performed a exercise intervention. The distress was measured using the distress management Test. Beck's Depression Inventory was used to measure depression. Beck's Anxiety Inventory was used to measure Anxiety Results: Both the experimental and control groups showed significant differences in distress, depression, and anxiety after the intervention (p<0.05) in the within-group comparisons. It was found that the experimental group showed more significant differences in distress, depression, and anxiety than the control group (p<0.05) when the two groups were compared. Conclusion: The results obtained in this study show that the neurofeedback program had a positive effect on distress, depression, and anxiety of life in patients with breast cancer. The study thereby proposes that the neurofeedback program should be applied as an intervention method for clinical use on patients with breast cancer.

  • This study was executed to examine the effect of group-psychotheray oriented psychodrama on child's depression. For this study self-reporting Kovacs's children's depression inventory(C.D.I) was administered for primary school children. and 8 children were selected in experimental and control group each. The experimental group acted the psychodrama for 15 session. The first follow-up test was executed at 8 weeks after pre-test and second follow-up test at 10 weeks after first follow- up. Every time children acted the psychodrama all behaviors had been recorded. Also in order to find out any changes in daily life after the psychodrama their parents class teachers and children themselves were interviewed. Basal depression level was 23.38 for experimental group and 23.63 for control group. Depression level of experimental group was reduced to 12.38(p<0.01) There was significant difference in depression level between experimental and control group (p<0.01) Reducing effect of experi ental group by the psychodrama was maintained as well. As a result group psychotherapy oriented psychodrama was effective to reduce depression level of childern. Group psychotherapy oriented psychodrama program for children need to be developed for more effectiveness.

  • Nowadays, most companies seek after the greatest profit by means of offering the goods which consumers want timely and efficiently and minimizing the cost of inventory and distribution channel which amounts to the great portion of total cost. And according as EC(Electronic Commerce) market has increased rapidly, SCM(Supply Chain Management) for EC become one of the most important facts for companies, therefore this paper suggest SCM scheme which EC, especially B to C, is added to the existing commerce system. This paper uses internet for information integration of distribution channel which is away from one another and applies TOC(Theory of Constraint)'s DBR(Drum-Buffer-Rope) Scheduling for synchronization through the whole supply chain. It is possible to synchronize the whole supply chain by means of making the speed of manufacturing and distribution to be controlled by consumer's order which is received in distribution center, and inventory and loss of sales opportunities are minimized by constant. Buffer Management. If inventories in distribution center is short, then it needs to search CCR(Capacity Constraint Resource) in supply chain and to control the speed of manufacturing and distribution according to the ability of CCR. This paper applies PT(Partial Transshipment) strategy for Delivery from distribution center to store or cyber consumer. the strategy this paper suggests chooses neighbour area from area which each distribution center takes charge, and then makes product ordered by cyber consumer which lives in the chosen area to be delivered according to inventory of distribution center.

  • Following the increasing importance of logistics function in today's company operation, this work explores the mechanism for cooperation within a supply chain, especially between a firm and an independent logistics supplier. We first characterize the optimal linear logistics contract based upon the recent developments in contract theory, and then investigate the effect of such a contract on the firm's inventory policy. The results indicate that the order quantity becomes smaller and the lead time becomes shorter and under the optimal contract than without the incentive scheme. Accordingly, the service level under the optimal contract becomes higher. These findings are in accordance with the literature on vertical control and JIT (Just in Time) philosophy.

  • It is difficult to determine an appropriate discount price for daily perishable products to increase profit from a long-term standpoint. Even if the discount pricing is efficient to increase profit of the day, consumers memorize the sales price and they might hesitate to purchase the product at a regular price the following day. The authors discussed the inventory clearance pricing for a single period in our previous study by constructing a mathematical model to derive an optimal sales price to maximize the expected profit by considering the reference price effect of demand. This paper extends the discussion to handle the discount pricing for multiple periods. A mathematical analysis is first conducted to reveal the properties on an objective function, which is the present value of total expected profits for multiple periods. An algorithm is then proposed to derive an optimal price for asymmetric consumers. Numerical experiments investigate the characteristics of the objective function and optimal pricings.

  • The purpose of this study was to investigate the relationship between internal locus of control in children and parents' child rearing attitudes which children perceive. For this purpose, 198 fifth grade boys and 163 fifth grade girls were randomly selected and their perception of their parents' child rearing attitudes and their locus of control were measured. Children's locus of control was measured by A Locus of Control Scale For Children of Nowicki & Strickland (1973) which was translated into Korean and item analysis of which was done. Ami Children's perception of their Darents' child rearing attitudes measured by Parent-Child Relationship Inventory which was constructed in Korean Testing Center. For the data analysis, t-test and two-way analysis of variance were applied and Pearson correlation coefficient was computed. The results of the present study were as follows; 1. The correlations between children's perception of their parents' child rearing attitudes and locus of control in children were significant partly. Especially, internal children reported their parents as showing less rejective attitude and less different child rearing attitude between father and mother. 2, Sons were more influenced by their parents' child Learing attitudes than daughters in the development of locus of control 3. Maternal child rearing attitude was more influential than paternal child rearing attitude in the development of locus of control.

  • Purpose: The purpose of this study was to examine the effects of music therapy on anxiety of patients in emergency room. Methods: The study was designed using a noneqivalent control group nonsynchronized design. For 20 minutes, the experimental group(22 patients) had listened to music and the control group(23 patients) had bed rest. A six-item state anxiety scale developed by Marteau and Bekker, which was based on Spielberger's State-Trait Anxiety Inventory, blood pressure and pulse rate were measured to all study participants before and after the intervention. The data was analyzed by the SPSS 12.0 program. Results: 1) The experimental group's state anxiety level were significantly lower than the control group's(t=2.220, p=.032). 2) There were no significant differences in both group's diastolic(t=-.495, p=.623) and systolic blood pressure(t=831, p=.411). 3) The experimental group's pulse rate was significantly lower than the control group's(t=2.363, p=.023). Conclusion: Music therapy may be applied as a nursing intervention to decrease anxiety in emergency room.
