Objective : The purpose of this study is not only to examine the negative functions of alcohol, but also to examine the positive functions and look at it with a balanced perspective. Methods : We investigated the number of times the word "酒"(alcohol) appears in 《Hwangjenaegyeong》 and 《Gyeongakjeonseo》. The meaning of alcohol was divided into seven categories. The number of positive and negative functions of alcohol was counted and the ratio was calculated. Results : 1. In the 《Hwangjenaegyeong》, the word alcohol appears 23 times, of which 9 times has positive functions, 10 times has negative functions, and the remaining 4 times does not correspond anywhere. The ratio of positive functions is 39.13% and negative functions 43.48%. 2. In the 《Gyeongakjeonseo》, the word alcohol appears 1,487 times, of which 1,140 times (76.66%) has positive functions, and 327 times (21.99%) has negative functions. Conclusions : 1. In 《Hwangjenaegyeong》, the number of comments about positive and negative functions of alcohol is similar. 2. 《Gyeongakjeonseo》 has commented a lot about the positive functions of alcohol. However, it has more mentions to negative functions of alcohol except for those related to herbs and prescriptions (48 to 64 chapter). 3. It is somewhat unreasonable to judge the emphasis on the positive and negative function of alcohol according to the number of references to alcohol in oriental medicine classics. But in these books, we can find a balanced approach between the two sides, not a one-sided biased view. 4. From a curative point of view, it is desirable to know and to use the positive and negative functions of alcohol, and drink alcohol as appropriate control.

Purpose: This study examined the effects of an insight-oriented nursing program on schizophrenic patients' insight, positive and negative syndromes, and depression. Method: A non-equivalent control group non-synchronized design was utilized. For this research, a total of 34 subjects were selected at a psychiatric hospital in Daegu during the period ranging from Oct. 1st, 2005 to Feb. 11th, 2006 (experimental group=17, control group=17). Result: After the treatment, between the experimental and control groups, there wasa significant difference in the level of SUMD(t=-4.52, p=.000) and positive syndrome(t=6.97, p=.013), but no significant difference in the negative syndrome(t=-1.81, p=.079) and depression(t=2.23, p=.145). Conclusion: The results of this study show that the insight-oriented nursing program works well for schizophrenic patients. Therefore, it is recommended that this program should be used in clinical practice as an effective nursing intervention for schizophrenic patients.

This paper focuses on study on PWM converter control under unbalanced network condition. Voltage unbalance in a three-phase system causes the performance deterioration by producing 120 Hz voltage ripples in the DC link and 120 Hz ripple in reactive power. To eliminate the ripples, both positive and negative sequence currents should be controlled simultaneously. In this paper four PI controllers on synchronous reference frame is implemented to control D and Q currents in both positive and negative sequence. Positive and negative sequence signal extraction is done using delay signal cancellation method. Simulation results show satisfactory performance in suppressing 120 Hz ripples.

A static synchronous compensator (STATCOM) applied to rapidly changing, highly unbalanced loads such as electric arc furnaces (EAFs), requires both positive-sequence and negative-sequence current control, which indicates fast response characteristics and can be controlled independently. Furthermore, a delta-connected STATCOM with cascaded H-bridge configuration accompanying multiple separate DC-sides, should have high performance zero-sequence current control to suppress a phase-to-phase imbalance in DC-side voltages when compensating for unbalanced load. In this paper, actual EAF data is analyzed to reflect on the design of current controllers and a pioneering zero-sequence current controller with a superb transient performance is devised, which generates an imaginary -axis component from the presumed response of forwarded reference. Via simulation and experiments, the performance of the positive, negative, and zero-sequence current control of a cascaded H-bridge STATCOM for EAF is verified.

The purpose of this study is to examine the online WOM effect of blog review depending on brand awareness and message direction. The theory of planned behavior was applied to understand online WOM acceptance. A survey was conducted targeting female in 20s and 30s and 312 questionnaires were used for analysis. Frequency analysis, reliability analysis, t-test, and regression analysis were conducted using SPSS ver. 18.0. The results are as follows. First, purchase intention and online re-WOM intention are higher when brand awareness is higher. Second, subjective norm, perceived behavioral control, WOM acceptance intention, purchase intention and off-line re-WOM intention show higher values when negative information is afforded. Third, in type 1 (high brand awareness/positive message) and type 3 (low brand awareness/positive message), attitude, subjective norm and perceived behavioral control have a positive effect on WOM acceptance intention. In type 2 (high brand awareness/negative message), subjective norm and attitude have a positive effect on WOM acceptance intention. In type 4 (low brand awareness/negative message), subjective norm and perceived behavioral control have a positive effect on WOM acceptance intention. Forth, in type 1 and type 3, WOM acceptance intention has a positive effect on purchase intention, offline re-WOM intention and online re-WOM intention. In type 2 and type 4, WOM acceptance intention has a negative effect on purchase intention, and a positive effect on offline re-WOM intention. The results show that blog review has ripple effect on consumer behavior by affecting purchase intention and offline re-WOM intention.

Objectives : The purpose of this study is to investigate effects of Syzygium aromaticum (SAE) spread on the allergic contact dermatitis caused by 2,4-dinitro-chlorobezene (DNCB). Methods : Forty-two mice were divided into six groups ; normal, negative control (DNCB-treated), positive control (DNCB + 1% pimecrolimus), experimental group I, II and III. control and experimental groups were induced allergic contact dermatitis by DNCB. Experimental group I(DNCB + 0.2% SAE), II(DNCB + 1% SAE) and III(DNCB + 5% SAE) were spread SAE and positive control was spread the 1% pimecrolimus. In this study, effect of SAE on clinical aspects on the skin, histopathological change, the blood level of IgE, cytokines, histamine were investigated. In addition, effect of SAE on spleen $CD4^+/CD8^+$ T cell subset was investigated. Results : 1. In experimental group I, II and III, erythemas and edema were more reduced than negative control. 2. In experimental group I, II and III inflammatory edema and the numbers of infiltrated inflammatory cells were more reduced than negative control. 3. In experimental group I, II and III, clinical skin score was more reduced than negative control. 4. In experimental group II and III, the thickness of skin was statistically significant reduced than negative control. 5. In experimental group II and III, histamine release was statistically significant reduced than negative control in dose-dependantly. 6. In experimental group II and III, cytokines (IL-1${\beta}$, TNF-${\alpha}$, IL-4, IL-6, IL-10) were statistically significant reduced than negative control in dose-dependantly. 7. In experimental group I, II and III, the level of total IgE was statistically significant reduced than negative control in dose-dependantly. 8. In experimental group III, $CD4^+$ and $CD8^+$ T cells were statistically significant decreased similar to the positive control. Conclusions : According to above experiments, Syzygium aromaticum(SAE) was effective on allergic contact dermatitis.

Objectives : The purpose of this study was to evaluate the potential of the test substance, SU-Eohyeol Pharmacopuncture (SUEP), to induce micronuclei in bone marrow cells of Sprague-Dawley (SD) Rats. Methods : The dose range preliminary study was performed first. 1 ml/animal was selected as the high dose of this study. Two additional lower dose levels (0.5 and 0.25 ml/animal) were produced by applying a geometric ratio of 2. In addition, the positive and negative control groups were set. Then, after intramuscular administration (1 ml/animal) of SUEP to 8-week-old male SD rats, an in vivo micronucleus test was performed to evaluate the induction of micronuclei in SD rat bone marrow cells. Results : As a result of the main study, the incidence of micronucleated polychromatic erythrocytes (MNPCE) in polychromatic erythrocytes (PCE) in the test substance SUEP groups was not statistically significantly different from the negative control group. In addition, the ratio of PCE to total erythrocytes in the test substance SUEP groups was not statistically significantly different from the negative control group. In the positive control group, the incidence of MNPCE in PCE was statistically significantly increased when compared to the negative control group. The ratio of PCE to total erythrocytes in the positive control group was not statistically significantly different from the negative control group. Conclusions : Based on these results, the test substance, SUEP, did not have any potential to induce micronuclei formation in bone marrow cells of rats under the conditions of this study.

To determine the efficacy of postoperative adjuvant chemotherapy with paclitaxel plus cisplatin (Taxol + DDP, TP therapy) for stage IIA esophageal squamous cell carcinoma (ESCC) and to investigate the expression of RUNX3 in lymph node metastasis-negative esophageal cancer and its relationship with medical prognosis, a retrospective summary of clinical treatment of 143 cases of stage IIA esophageal squamous cell carcinoma patients was made. The patients were divided into two groups, a surgery alone control group (52 patients) and a chemotherapy group that received postoperative TP therapy (91 patients). The disease-free and 5 year survival rates were compared between the groups and a multivariate analysis of prognostic factors was performed. The same analysis was performed for cases classified as RUNX3 positive and negative, with post-operative specimens assessed by immunohistochemistry. Although the disease-free and 5 year survival rates in control and chemotherapy groups did not significantly differ and there was no significance in RUNX3 negative cases, postoperative adjuvant chemotherapy in the chemotherapy group was shown to improve disease-free and 5 year survival rate compared to the control group in RUNX3 positive cases. On Cox regression multivariate analysis, postoperative adjuvant chemotherapy (P<0.01) was an independent prognostic factor for RUNX3 positive cases, suggesting that postoperative TP may be effective as adjuvant chemotherapy for stage IIA esophageal cancer patients with RUNX3 positive lesions.
