In this paper, the harmonic displacement response of a damaged square plate with all-over part-through damage parallel to one edge is utilized as the input signal function in wavelet analysis. The method requires the properties of the damaged plate, i.e., no information about the original undamaged structure is required. The location of damage is identified by sudden changes in the spatial variation of transformed response. The incurred damage causes a change in the stiffness or mass of the plate. This causes a localized singularity which can be identified by a wavelet analysis of the displacement response. In this study via numerical examples shown by using harmonic response is more versatile and effective compared with the static deflection response, specially in the presence of noise. In the light of the obtained results, suggestions for future work are presented and discussed.

In recent years, an increasing number of reports have explored the wound healing mechanism of these two traditional Chinese herbal medicines- Panax ginseng and Panax notoginseng, but there is no systematic research on the related core functions and different mechanisms in the treatment of wound healing up to now. Based on network pharmacology and meta-analysis, the present work aimed to comprehensively review the commonality and diversity of P. ginseng and P. notoginseng in wound healing. In this study, a wound healing-related "ingredients-targets" network of two herbs was constructed. Thereafter, meta-analysis of the multiple target lists by Metascape showed that these two medicines significantly regulated blood vessel development, responses to cytokines and growth factors and oxygen levels, cell death, cell proliferation and differentiation, and cell adhesion. To better understand the discrepancy between these two herbs, it was found that common signaling pathways including Rap1, PI3K/AKT, MAPK, HIF-1 and Focal adhesion regulated the functions listed above. In parallel, the different pathways including renin-angiotensin system, RNA transport and circadian rhythm, autophagy, and the different metabolic pathways may also explained the discrepancies in the regulation of the above-mentioned functions, consistent with the Traditional Chinese Medicine theory about the effects of P. ginseng and P. notoginseng.

The study was conducted from May to September in 1994 to investigate applicability of the Hearing Handicap Inventory for the Elderly-Screening version(HHIE-S) in parallel with the pure-tone audiometer to the initial screening test of noise-induced hearing loss(NIHL) in some noise-exposed workers. Subjects were selected by systemic sampling that took every 10th person from 6, 700 workers taking the annual occupational health examination by the department of Health Maintenance of Dongsan Hospital Keimyung University in Taegu. The authors administered the pure-tone audiometric test and self-reported questionnaire of HHIE-S including items of sociodemographic and job-related variables concurrently. The final subjects analysed were 1,019(488 males and 531 females) excluding fourteen persons who had many missing values in their questionnaires. The reliability coefficients of HHIE-S scale by Cronbach's alpha were 0.84. In the univariate analysis of hearing handicap measured by the HHIE-S, work duration, military service and the hearing threshold loss at 1KHz and 4KHz by the initial audiometer were significant in males while age, work duration and hearing threshold loss at 1KHz and 4KHz were significant in females. In the stepwise linear regression analysis, hearing threshold loss at 1KHz and 4KHz, was the only selected variable explaining the hearing handicap in males and hearing threshold loss at 1KHz and 4KHz, age, and work duration were selected in females. In ROC curves for HHIE-S scores against NIHL as gold standard which was defined by the follow-up audiogram as more than 30dB of the average of 0.5/1/2KHz and 50dB at 4KHz, the optimal cutoff for the parallel HHIE-S appeared to be 8. The results suggest that HHIE-S appeared to have some reliability and validity in this data and might be used in screening NIHL in parallel with pure-tone audiometer in noise-exposed workers.

One bottle system was recently developed in order to simplify the clinical skills and save chair time after continuous improvements on dentin bonding agents. There has been many studies to measure the bond strength of one bottle systems but no actual work has been done on micromorphologic study of resin-dentin interdiffusion zone after one bottle system application. To evaluate the bonding patterns of various commercially available one bottle systems to dentin, observation of resin-dentin interdiffusion zone under TEM was performed. Caries-free human third molars within one month of extractions were chosen for the experiments. The molars were sectioned 1mm above the cementoenamel junction and got rid of the root portions. Crown portions of the teeth were sectioned parallel to occlusal surface so that dentin discs of 1mm in thickness were remained. 7 one bottle systems and 1 two bottle system were applied according to manufacturer's instructions and followings were the results. 1. In every experimental groups, cross bandings of collagen fiber were distinguishable and tight bon dings between the bonding agents and dentin were observed. 2. Hybrid layer was clearly observed in ONE-STEP$^{(R)}$, Prime & Bond$^{(R)}$ 2.1, Syntac$^{(R)}$ SC, MAC-BOND II groups but it was not clear in Single Bond, D-Liner Dual PLUS, ONE COAT BOND groups. 3. Electron-density of hybrid layer was uniform in pattern in MAC-BOND II, Prime & Bond$^{(R)}$ 2.1 groups but not so uniform in ONE-STEP$^{(R)}$ group. 4. Electron-dense amorphous phase in most superior layer of the resin-dentin interdiffusion zone was characteristically observed in Single Bond, Syntac$^{(R)}$ SC, ONE COAT BOND groups. It can be concluded that bondings between the dentin bonding agents and dentin can be various in pattern according to their chemical compositions and the condition during applications.

Purpose: The purpose of this study was to investigate the effects of Wheel of Wellness counseling on wellness lifestyle, depression, and health-related quality of life in community dwelling elderly people. Methods: A parallel, randomized controlled, open label, trial was conducted. Ninety-three elderly people in a senior welfare center were randomly assigned to two groups: 1) A Wheel of Wellness counseling intervention group (n=49) and 2) a no-treatment control group (n=44). Wheel of Wellness counseling consisted of structured, individual counseling based on the Wheel of Wellness model and provided once a week for four weeks. Wellness lifestyle, depression, and health-related quality of life were assessed pre-and post-test in both groups. Results: Data from 89 participants were analyzed. For participants in the experimental group, there was a significant improvement on all of the wellness-lifestyle subtasks except realistic beliefs. Perceived wellness and depression significantly improved after the in the experimental group (n=43) compared to the control group (n=46) from pre- to post-test in the areas of sense of control (p =.033), nutrition (p =.017), exercise (p =.039), self-care (p <.001), stress management (p =.017), work (p =.011), perceived wellness (p =.019), and depression (p =.031). One participant in the intervention group discontinued the intervention due to hospitalization and three in the control group discontinued the sessions. Conclusions: Wheel of Wellness counseling was beneficial in enhancing wellness for the community-dwelling elderly people. Research into long-term effects of the intervention and health outcomes is recommended.

Purpose: This study aimed to identify occupational stress and health problems as well as turnover reasons among leavers in novice nurses and to estimate factors which might affect turnover by comparing them to stayers. Methods: In this study, secondary analysis of data gathered from the Shift Work Nurse's Health and Turnover studies, was carried out. The data were collected from 204 stayers who have been working for 18 months since 2018 and 48 leavers who left within the same period at two tertiary hospitals in Seoul. The reasons for turnover, occupational stress, and 8 types of health problems were recorded. The data were analyzed using SAS 9.4 to obtain descriptive statistics. In parallel, Pearson's chi-squared test, Fisher's exact test, and independent t-test were also conducted. Results: The main reasons for turnover were job stress and difficult interpersonal relationships in the workplace. Occupational stress of leavers was higher than stayers, especially in the subscales of interpersonal conflict, organizational system, lack of reward, and occupational climate. Among the 8 types of health problems, the depression prevalence of leavers was higher compared to stayers and showed marginal significance. Unexpectedly, the sleep disturbance prevalence of stayers was significantly higher compared to leavers. Conclusion: To reduce the turnover rate of novice nurses, education on how to cope with occupational stress is needed. A customized program for novice nurses to overcome the difficulties of interpersonal relations would be helpful.

The purpose of this study is to find out whether the many start-up support programs provided by a college can actually help students start a business, and to discuss what role colleges should have as facilitators of student entrepreneurship. To this end, a qualitative study was conducted with seven students who wished to start a business by utilizing start-up education and support programs provided by College Y. As a result of the study, the participants first mentioned parallel and administrative inefficiency in entrepreneurship and the entrepreneurship programs. Second, the implications for the role of colleges in fostering start-up content are systematic planning and guidance for start-up programs operated by the college, concise administrative procedures, mentoring in various start-up items, and securing a test market. It can be said that the concept of a common office in which students can work together is necessary. The study is significant in that it can help to establish a start-up support plan by suggesting what role colleges should play in relation to entrepreneurship, but its limitation is that its scope includes only one specific major.

Korean has a pair of voiceless fricatives, whose laryngeal manifestation comes in parallel to stops and affricates with a three-way lexical contrast. Prior phonetic studies by Kagaya (1974), Iverson (1983), and Kang (1999, 2000) point out /s/ is associated with multiple characteristics of the larynx shared with not only the lax but also the aspirated series, whereas /s' / carries a laryngeal distinction typical of the tense consonants. The complex dual nature of /s/ is again supported by a psycholinguistic study by Kang (2004), as /s/ was found to interact with /$c^h$/ (17% of the time) as well as /c/ (57%) in speech errors. In addition, a recent work by Cho and Lee (2003) notes an interesting chain shift case in the acquisition of the fricatives. Although they observed a significant phonological pattern between child English and Korean, Cho and Lee's description of acquiring fricatives is far from being precise from the perspective of phonetics. From a longitudinal study of recorded tapes by two children at 1;7-3;8 and 1;7-2;1 respectively, I found that /s' / was usually substituted into tense noncontinuants in young children's early production as predicted, whereas /s/ having both lax and aspirated-like glottal properties revealed a complicated pattern of substitutions into lax, tense, and aspirated noncontinuants with a varying degree of preference relative to the subjects. The current acquisition study supports the previous claims concerning fricatives in other languages, showing that their acquisition comes after stops. Besides, it also notes that Korean fricatives are subject to a series of phonological processes called stopping, affricating, tensifying and palatalizing during the transitional period of phonological development by young children. Moreover, between the two voiceless types, /s/ was acquired earlier than /s'/ as the unmarked segment.

Objectives : This study aims to design a method for drying forceps jars. As part of the process, holes were made in the forceps jars. Drying time, rate of wet pack, and cost of rewashing linen were then determined. Moreover, the study looked into the bacteria incidence rate in the forceps jars. This study suggests a practical way for preventing infection in a hospital through a surgical device. Methods : This study investigated the effect of forceps jars with holes on reducing drying time, rate of wet pack, and cost of rewashing linen. It also looked into the bacteria incidence rate in the forceps jars through a parallel design. Data was collected and analyzed using SPSS version 21. Results : The drying time of a forceps jars was remarkably reduced from $18.44{\pm}0.2$ minutes(non-hole forceps jars) to $0.58{\pm}0.02$ minutes(4-hole forceps jars). The rate of wet pack of non-hole forceps jars was 51.4%. However, the rate of 4-hole forceps jars reached 4.6%. The cost of rewashing linen saw a decline from 38,073 won to 3,381 won. In addition, no bacteria and virus were detected from the 24-hours usage of forceps jars even though the jars had holes. Conclusions : The 4-hole forceps jars greatly increased work efficiency as a result of the reduced drying time, rate of wet-pack and cost of rewashing linen. The 4-hole forceps jars did not influence their sterilizing effect.
