Human resources specialized in product development (PD) being essential in industry to enhance their competitiveness in the market with differentiated products, the PD curricula of domestic universities are in need of restructuring to better provide a comprehensive and diverse spectrum of knowledge as well as practical experiences for PD. We compared the PD curricula of selected domestic and foreign universities and identified advanced features of PD curricula. The major portion of the information used in our benchmarking of the seven, three domestic and four foreign, universities is obtained through their official websites. At domestic universities, the PD curricula comes in different sizes and is administered at the departmental level. On the other hand, each foreign university has her own unique form of PD curricula which is formulated on the firm basis of multidisciplinary collaboration among schools of Engineering, Management, and Arts with diversified program options ranging from giving course credits to offering various certificates and degrees. The industrial sponsorship in the form of financial support and mentorship at foreign universities is much more noticeable than at domestic universities. The survey results of the present study can be effectively utilized to develop an effective PD curriculum.

The analysis of beauty major students' acceptance intentions for digital new technologies revealed that subjective norms and self-efficacy significantly impact ease of use as mediating variables, and willingness to innovate and self-efficacy significantly impact usefulness as mediating variables. However, willingness to innovate did not significantly impact ease of use, and subjective norms did not significantly impact usefulness. Ease of use and usefulness significantly impacted acceptance attitude, and acceptance attitude significantly impacted acceptance intention. These results suggest that while beauty major students recognize the positive necessity of new technology application in the beauty field, they may feel somewhat burdened by learning and utilizing new technologies. Learners' fear of applying new technologies could result in a reluctance to take courses necessary for understanding and acquiring digital new technologies. To address this, it is necessary to analyze the basic knowledge level of digital technology among beauty major students and develop lower-level related courses and programs to help them easily understand digital new technologies.

The study was designed to provide the fundamental information for understanding discomfort of bone marrow donors and for promoting an individual comfort by comparing the difference on discomfort between unrelated donors and related donors. The subject of the study was fifty related donors and thirty unrelated donors who was in the C University Hospital. This survey had been carried out and collected from October, 1998 to March, 1999. The scale of discomfort of donors associated with bone marrow donation were assessed by the questionnaire deviced by Kim Sang Dol and amended by the researcher. Data was analyzed by $x^2-test$, t-test, two-way ANOVA, and Pearson Correlation Coefficients. The results were as follows. 1. Considering the general characteristics of bone marrow donors according to gender, male was consisted of $60\%$ and female was consisted of $40\%$. Of those related donors are consisted for $62.5\%$ and accounted for $37.5\%$ of those unrelated donors. Considering the classification to the job, employee of company were major donors which was $35\%$, and next order was student, individual businessman, and housewife. Considering the education level. college students were $48.7\%$ and students who have less than high school level were $42.5\%$. 2. According to the above the results regarding discomfort of bone marrow donation, it is especially shown that the major cause for discomfort of bone marrow donors is on physical factor. The concrete examples for physical factor are pain in the region of bone marrow harvest and pain in the injection part by fluid therapy and blood-sampling, an immovability of the body after bone marrow harvest, and difficulties on walking. Considering physiological factor, there are an uneasiness about leading to injure their health, vague fear about the hospital. and a tedium at hospital. Environmental factors for discomfort of bone marrow donors are insufficient explanation for needle gauge and procedure of bone marrow donation and difficulty on following medical schedule. Therefore. it is necessary to establish more effective and systematically organized program for nursing intervention based on the research results. An effective program is only useful in getting rid of discomfort of bone marrow donors.

The purpose of the study is to microscopically re-clarify the reality of renovation and conflicts that females faced within their families since the modernization period. The research method is the literature review. Families have been considered based on the formation of individual spaces for housing by husband and wife. The study will analyze changes in daily lives and housing consciousness to understand how such housing areas are transforming. The results of the study are as follows. From the perspective of symbolic interaction, in a traditional society, Korean females have been experiencing alienation and isolation in private areas in their daily lives due to family centrism and male chauvinism. Since industrialization, the female's role as the major consumer has been emphasized. Also, in terms of housing space, the symbol of family interaction was influenced more by utility, rationality, and equality than spatial hierarchy. From the perspective of the dailiness of phenomenological traditions, the modern girl's housing consciousness, which appeared during modernization under colonial rule, is considered as revolutionary from traditional society. Soon after in industrialized society, females appeared as leaders of 'sweet home'. They also became the main body to create the space for living by giving meaning to the interior of housing. Considering dailiness from the Marxist perspective, under the colonial social system, females became the subject of colonization through education, socialization, and the labor market. The modern public system presents the female as 'a wise mom and good wife' or laborer causing the colonization of her life. After industrialization, the socialization of housing and prioritization of spending caused the daily lives of females to become colonized by the consumption market.

In recent earthquakes, the failure of ceiling systems has been one of the most widely reported damage and the major cause of functionality interruption in some buildings. In an effort to mitigate this damage, some scholars have studied a series of ceiling systems including plaster ceilings and mineral wool ceilings. But few studies have involved the backdrop metal ceiling used in some important constructions with higher rigidity and frequency such as the main control area of nuclear power plants. Therefore, in order to evaluate its seismic performance, a full-scale backdrop metal ceiling system, including steel runners and metal panels, was designed, fabricated and installed in a steel frame in this study. And the backdrop metal ceiling system with two perimeter attachments variants was tested: (i) the ends of the runners were connected with the angle steel to form an effective lateral constraint around the backdrop metal ceiling, (ii) the perimeter attachments of the main runner were retained, but the perimeter attachments of the cross runner were removed. In the experiments, different damage of the backdrop metal ceiling system was observed in detail under various earthquakes. Results showed that the backdrop metal ceiling had good integrity and excellent seismic performance. And the perimeter attachments of the cross runner had an adverse effect on the seismic performance of the backdrop metal ceiling under earthquakes. Meanwhile, a series of seismic construction measures and several suggestions that need to be paid attention were proposed in the text so that the backdrop metal ceiling can be better applied in the main control area of nuclear power plants and other important engineering projects.

Background: Lung cancer is a major cause of Korean female mortality and is clearly associated with smoking. The Korean National Health and Nutrition Examination Survey (KNHANES IV-2,3), which included both self-reports of smoking and urinary cotinine data, revealed a significant discrepancy between the prevalence of self-reported and biochemically-verified female smokers. The factors associated with accurate self-reporting of current smoking status remain poorly understood, however. Materials and Methods: We assessed the prevalence of smoking in KNHANES using both self-report and urinary cotinine data. Subsequently, using univariate and multivariate tests, we assessed whether age, intensity of smoking, marital status, relationship with cohabitants, education, occupation, residential area, or annual household income were associated with inaccurate self-reporting in Korean females. We also investigated whether the prevalence of inaccurate self-reports changed over the survey period, 2008-2009. Results: The prevalence of self-reported smoking was 47.8% in males and 6.6% in females. By contrast, the prevalence of smoking as assessed by urinary cotinine levels was 52.2% in males and 14.5% in females. Of the 746 females with urinary cotinine levels >50ng/ml, 407 (56.0%) provided inaccurate self-reports. In a multivariate model, age group(40-49: OR 3.54, 95%CI 1.42-8.86, p=0.007; ref :20-29), cotinine intensity(OR 0.999, 95%CI 0.998-0.999, p<0.001), marital status (married but without spouse: OR 0.37, 95%CI 0.15-0.94, p=0.037; ref :never married), relationship with cohabitants (living with a spouse and unmarried child: OR 2.63, 95%CI 1.44-4.80, p=0.002; living with 2 generations except unmarried child: OR 2.53, 95%CI 1.09-5.87, p=0.030; living with ${\geq}3$ generations: OR 3.25, 95%CI 1.48-7.10, p=0.003; ref :spouse only) and education(college or higher: OR 2.73, 95%CI 1.04-7.18, p=0.042; ref :elementary or less) were independently associated with inaccurate self-reports. Conclusions: The trend of smoking prevalence of Korean females is likely to decrease. However, an elevated prevalence of inaccurate self-reports by females remains. Factors related to the intensity of smoking and family status appear to influence whether a Korean female provides an accurate self-report when asked about smoking behavior.

Objectives: Although the prevalence of depressive disorders in South Korea's general population is known, no reports on the prevalence of depression among patients who visit primary care facilities have been published. This preliminary study was conducted to identify the prevalence of depressive disorder in patients that visit two primary care facilities. Methods: Among 231 consecutive eligible patients who visited two primary care settings, 184 patients consented to a diagnostic interview for depression by psychiatrists following the Diagnostic and Statistical Manual of Mental Disorders-IV criteria. There were no significant differences in sociodemographic characteristics such as gender, age, or level of education between the groups that consented and declined the diagnostic examination. The prevalence of depressive disorder and the proportion of newly diagnosed patients among depressive disorder patients were calculated. Results: The prevalence of depressive disorder of patients in the two primary care facilities was 14.1% (95% confidence interval [CI], 9.1 to 19.2), with major depressive disorder 5.4% (95% CI, 2.1 to 8.7), dysthymia 1.1% (95% CI, 0.0 to 2.6), and depressive disorder, not otherwise specified 7.6% (95% CI, 3.7 to 11.5). Among the 26 patients with depressive disorder, 19 patients were newly diagnosed. Conclusions: As compared to the general population, a higher prevalence of depressive disorders was observed among patients at two primary care facilities. Further study is needed with larger samples to inform the development of a primary care setting-based depression screening, management, and referral system to increase the efficiency of limited health care resources.

With ongoing development of earthquake engineering research and the lessons learnt from a series of strong earthquakes, the seismic design concept of "resilience" has received much attention. Resilience describes the capability of a structure or a city to recover rapidly after earthquakes or other disasters. As one of the main features of urban constructions, tall buildings have greater impact on the sustainability and resilience of major cities. Therefore, it is important and timely to quantify their seismic resilience. In this work, a quantitative comparison of the seismic resilience of two tall buildings designed according to the Chinese and US seismic design codes was conducted. The prototype building, originally designed according to the US code as part of the Tall Building Initiative (TBI) Project, was redesigned in this work according to the Chinese codes under the same design conditions. Two refined nonlinear finite element (FE) models were established for both cases and their seismic responses were evaluated at different earthquake intensities, including the service level earthquake (SLE), the design-based earthquake (DBE) and the maximum considered earthquake (MCE). In addition, the collapse fragility functions of these two building models were established through incremental dynamic analysis (IDA). Based on the numerical results, the seismic resilience of both models was quantified and compared using the new-generation seismic performance assessment method proposed by FEMA P-58. The outcomes of this study indicate that the seismic resilience of the building according to the Chinese design is slightly better than that according to the US design. The conclusions drawn from this research are expected to guide further in-depth studies on improving the seismic resilience of tall buildings.

The stem barks of Fraxinus rhynchophylla was extracted with 95% EtOH, and the concentrated extract was successively partitioned with $CH_2Cl_2$, n-BuOH, and $H_2O$ in order to investigate the major phytochemicals. From the $CH_2Cl_2$ soluble fraction, a sterol (1) was isolated through the repeated silica gel column chromatographies. Three additional compounds (2-4) were isolated from the n-BuOH soluble fraction through silica gel, RP-18, and Sephadex LH-20 column chromatographies. Their chemical structures were elucidated as daucosterol $(1;{\beta}-sitosterol-3-O-{\beta}-D-glucopyranoside)$, caffeic acid (2), 6,8-dihydroxy-7-methoxycoumarin (3), and coniferaldehyde glucoside (4) by comparing their spectral data with those in the literatures. All isolates (1-4) were the first to be isolated from F. rhynchophylla.

Objectives: Household overcrowding (HC) can contribute to both physical and mental disorders among the members of overcrowded households. This study aimed to measure the status of HC and its main determinants across the provinces of Iran. Methods: Data from 39 864 households from the 2016 Iranian Household Income and Expenditures Survey were used in this study. The Equivalized Crowding Index (ECI) and HC index were applied to measure the overcrowding of households. Regression models were estimated to show the relationships between different variables and the ECI. Results: The overall, urban, and rural prevalence of HC was 8.2%, 6.3%, and 10.1%, respectively. The highest prevalence of HC was found in Sistan and Baluchestan Province (28.7%), while the lowest was found in Guilan Province (1.8%). The number of men in the household, rural residency, the average age of household members, yearly income, and the household wealth index were identified as the main determinants of the ECI and HC. Conclusions: The study demonstrated that the ECI and HC were higher in regions near the borders of Iran than in other regions. Therefore, health promotion and empowerment strategies are required to avoid the negative consequences of HC, and screening programs are needed to identify at-risk families.
