With the common objective to improve process productivity and product quality, statistical process control (SPC) and engineering process control (EPC) have been widely used in the discrete-parts industry and the process industry, respectively. The major focus of SPC is on process monitoring, while that of EPC is on process adjustment. The emergence of the hybrid industry necessitates a synergistic combination of the two methods for an effective process control. This paper investigates the existing studies on SPC, EPC, and the integration of the two methods. This paper also presents future research issues in this field.

Kidney and liver are the major organs of metabolism and excretion of drugs. Renal and Hepatic impairment may affect the pharmacokinetics/pharmacodynamics and the safety of drugs. Adjusting the dosage based on organ function is the essential role of pharmacists. However, differences have been noted on the recommended dosage among the literatures. We compared and analyzed the recommendations of 4 literature sources which are commonly used for dosage adjustment. From April, 2011 to August, 2011, we selected data on recommendations for dosage adjustment for impaired renal and hepatic function of 100 drugs through a protocol. We analyzed the definition terms of renal and hepatic impairment, recommendations for dosage adjustment, evidenced references in four literature sources: Korean National Formulary (KNF), American Hospital Formulary System Drug Information (AHFS), Micromedex (MM) and Drug Prescribing of Renal Failure (DPRF). We further examined the data homogeneity by comparing how drugs that required no adjustment according to one source were categorized by the other. Sources use different definition terms among themselves except DRPF. Presence or absence of evidenced references about renal/hepatic functional states are KNF (0%/0%), AHFS (78%/62.6%), MM (87.5%/65.6%) and DPRF (93.2%/no recommendation) respectively. Recommendations of specific dosage and dosing interval are KNF (24%/13%), AHFS (39.6%/12.1%), MM (50%/17.7%), and DPRF (55.4%/no recommendation) respectively. Regarding the data homogeneity, the differences were remarkable. Drugs with no adjustment according to AHFS were categorized to be adjusted/ contraindicated by KNF, MM, DPRF and the values were (44%/5.6%), (22%/0%), and (36%/0%) in renal function, (39%/6.5%), (19%/3.2%), and (no recommendation/no recommendation) in hepatic function respectively. Our study shows remarkable definite variation in definitions and recommendations about definition terms, information of dosage and interval, presence or absence of evidenced references. Especially for KNF, quantitative recommendations on dosages and dosing intervals should be made in the near future. To maximize the drug effect and safety and to minimize the heterogeneity of the literature sources, reviewing at least two sources are suggested when recommending the proper dosage adjustment based on organ function.

This study aims to investigate the effects of the Big Five Aspects on psychological adjustment and the practical use of the Big Five Aspects in personality studies. Correlations between psychological adjustment(subjective well-being, life satisfaction, anxiety, depression) and the Big Five Aspects were compared to correlations between the Big Five and psychological adjustment. The results showed distinction between two aspects within each of the Big Five that major personality traits that are actually related to psychological adjustment were found. Multiple regressions were used with subjective well-being, life satisfaction, anxiety, and depression as criterion variables to investigate the effect of the Big Five Aspect on psychological adjustment and the results are as followed. Big Five Aspects accounted for 66.2% of the variance in subjective well-being and withdrawal, compassion, industriousness, enthusiasm, assertiveness, openness significantly predicted subjective well-being. Life satisfaction and depression were significantly predicted by withdrawal and enthusiasm. Withdrawal was the only variable that significantly predicted anxiety. Multiple regression also showed that withdrawal and enthusiasm were the most consistent, accountable variables in predicting overall psychological adjustment. This findings indicate that individual's personality traits played a significant role in predicting subjective well-being and mental health as consistent with past findings, and that the Big Five Aspects can offer more detailed and specific description than the Big Five can. Finally, the research discusses implications, limitations and suggestions for further studies.

Background: The purpose of this study is to assess the degree of self-awareness, recognition of others, and adaptation to college life of dental hygiene students, and to identify the factors affecting college life adjustment. Methods: The effect size was calculated using the G*power 3.1.9.4 program, based on the data of 191 people who agreed to participate in the questionnaire. Independent samples t-test, one way ANOVA, Post HOC Scheffe, correlation analysis, and multiple regression analysis were conducted to explore the difference and correlation between self-awareness, perception of others, and college life adjustment according to general characteristics. Results: A significant positive correlation was found in self-awareness (r=.301). The highest positive correlations were with social adjustment in both private (r=.340) and public self-awareness (r=.331) (p<0.01). Recognition of others (r=-.051) showed a negative correlation with college life adjustment, though it was not statistically significant. As factors for adapting to college life, private self-awareness (β=.232) and public self-awareness (β=.254) had a positive (+) effect, and internal self-awareness (β=-.205) was found to have a negative (-) effect (p<0.01) Conclusion: The self-awareness and recognition of others among dental hygiene students influence their smooth adjustment to college life. Improvement measures are recommended to enhance adaptability to college life and develop core competencies related to their major

The performance of a modeling system consisting of WRF model v3.3 and CMAQ model v4.7.1 for forecasting $PM_{2.5}$ concentrations were evaluated during the period May 2012 through December 2014. Twenty-four hour averages of $PM_{2.5}$ and its major components obtained through filter sampling at the Bulgwang intensive measurement station were used for comparison. The mean predicted $PM_{2.5}$ concentration over the entire period was 68% of the mean measured value. Predicted concentrations for major components were underestimated except for $NO_3{^-}$. The model performance for $PM_{2.5}$ generally tended to degrade with increasing the concentration level. However, the mean fractional bias (MFB) for high concentration above the $80^{th}$ percentile fell within the criteria, the level of accuracy acceptable for standard model applications. Among three bias correction methods, the ratio adjustment was generally most effective in improving the performance. Albeit for limited test conditions, this analysis demonstrated that the effects of bias correction were larger when using the data with a larger bias of predicted values from measurement values.

Sexual life is one of the most important things for the quality of living, which nobody can ignore. Especially, spinal cord injury is one of the most typical disabilities, which can cause abrupt changes of sexuality. Hence, sexual adjustment and its subordinate problems have to be dealt with among various problems caused by spinal cord injury. The purpose of this study was to comparative sexual interest and adjustment between the married and the unmarried people with SCI. A total of 134 persons who were registered members of SCI organization and admitted rehabilitation unit between February and June 1999 were included in the study. The sample consisted of 69 unmarried and 64 married people with SCI. Participants answered the 15 items concerning sexual interest, sexual adjustment. The results are as follows: 1) The mean score of sexual interest for the unmarried was 16.4. From seven topics related to sexuality, the greatest interest was to cope emotionally with changes in sexual functioning. For the married, mean score of sexual interest was 13.8 and the greatest interest was to help a partner cope emotionally with limitation on sexual dysfunction. There were significant difference sexual interest between two groups (t=3.75, p= .00). 2) Each mean score for sexual adjustment in the married and the unmarried was 20.0, 19.6. There were no significance difference sexual interest between two groups (t=.24, p= .811). However, there was a statistically significant difference of sexual interest. 3) Sexual interests and adjustments are not correlated in case of the unmarried that have r score= .224, while they are corrlated in case of the married that have r= .398. Because the average age of the SCI becomes lower and lower, sexual rehabilitation programs should be given the unmarried as well as the married with SCI. In conclusion, the spinal injured's major concerns about their sexual life are different between the married and the unmarried-the unmarried are interested in practical problems such as methods and techniques to achieve sexual satisfaction and their fertility, while the married give priority to considerations about their spouse. Paying attention to different sexual interest according to marital status, we should make two different sexual rehabilitation programs for each group. One program including support groups with their sposes for the married, the other program to give a chance t o solve problems of sexuality for the unmarried with SCI.

Purpose: Factors related to the major satisfaction of nursing students were systematically searched and quantitatively synthesized. Methods: Meta-analysis was conducted upon 47 articles in Korean master and doctorate degree dissertations and academic journals. Meta-analysis of major satisfaction-related variables was conducted using Comprehensive Meta-Analysis (CMA) 2.0 program. The effect size of the related variables was analyzed by converting the statistic r value to Fisher's Z. Results: The overall average effect size of major satisfaction was the largest effect size (ES=.49), followed by cognitive factors (ES=.58), affective factors (ES=.45), and psychomotor factors (ES=.31). The cognitive factors were in the order nursing professionalism(ES=.70), nurse's image (ES=.65), and critical thinking disposition (ES=.36). The affective factors were self-esteem (ES=.59), emotional intelligence (ES=.55), career identity (ES=.49), self-efficacy (ES=.48), college adjustment (ES=.45), practice satisfaction (ES=.45), resilience (ES=.42), (ES=.40), grit (ES=.34), and stress (ES=.26). The psychomotor factors were clinical performance ability (ES=.38) and career search behavior (ES=.31). Conclusion: The results of this study are valuable when giving consideration to the variables related to nursing students' major satisfaction, for developing a strategic model to enhance the satisfaction of nursing students.
