Purpose: This study aimed to investigate factors affecting the problem solving ability of nursing students. Methods: The data in this study was collected through structured questionnaires from September 1st to October 30th, 2021. Study participants were 172 fourth grade nursing students at four departments of nursing located in B and K city. IBM SPSS WIN v 21.0. program with t-test, ANOVA, Scheffe' test, Pearson's correlation coefficients, and hierarchical regression was used for data analysis. Results: The mean scores of academic self-efficacy was 3.88±051, empathy was 3.76±0.33, communication skills were 3.94±0.48, and problem solving ability was 3.70±0.40. There were significantly positive correlations between problem solving ability and academic self-efficacy (r=.45, p=<.001), empathy (r=.51, p=<.001), communication skills (r=.52, p=<.001), Factors affecting participants' problem solving ability were empathy (β=.31, p=<.001), and communication skills (β=.23, p=.006), which explained about 38.4% of the problem solving ability. Conclusion: In this study, it is necessary to develop curricular and non curricular nursing program that can strengthen empathy and good communication skills together when developing programs that increase problem solving ability.

Dendropanax morbiferus H. Lev has been reported to have some pharmacologic activities and also interested in functional cosmetics. We found that the water extract of D. morbiferus leaves significantly inhibited tyrosinase activity and melanin formation in α-melanocyte stimulating hormone (MSH)-induced B16-F10 cells. D. morbiferus reduced melanogenesis-related protein levels, such as microphthalmia? associated transcription factor (MITF), TRP-1, and TRP-2, without any cytotoxicity. Two active ingredients of D. morbiferus, (10E)-9,16-dihydroxyoctadeca-10,17-dien-12,14-diynoate (DMW-1) and (10E)-(?)-10,17-octadecadiene-12,14-diyne-1,9,16-triol (DMW-2) were identified by testing the anti-melanogenic effects and then by liquid chromatography-tandem mass spectrometry (LC/MS/MS) analysis. DMW-1 and DMW-2 significantly inhibited melanogenesis by the suppression of protein kinase A (PKA)/cyclic AMP (cAMP)-responsive binding protein (CREB) and p38 MAPK phosphorylation. DMW-1 showed a better inhibitory effect than DMW-2 in α-MSH-induced B16-F10 cells. D. morbiferus and its active component DMW-1 inhibited melanogenesis through the downregulation of cAMP, p-PKA/CREB, p-p38, MITF, TRP-1, TRP-2, and tyrosinase. These results indicate that D. morbiferus and DMW-1 may be useful ingredients for cosmetics and therapeutic agents for skin hyperpigmentation disorders.

Context-awareness is an important element that can provide service of good quality according to users' surrounding environment and status in ubiquitous computing environment. Information gathering tools for context-awareness use small size mobile devices which have easy movement and a mobile agent in mobile device. Now, Mobile agents are consuming much times and expense to collect and recognize each users' context information. Therefore, needs research about structure for users' context information awareness in early time to reduce mobile agent's load. This paper proposes a P2P mobile agent structure that mikes filtering techniques and a P2P agent in mobile agent. The proposed structure analyzes each user's context information in same area, and groups users who have similar preference degree. Grouped users share information using a P2P mobile agent. Also this structure observes and learns to continue on users' action and service, and measures new interrelation.

Purpose: This study aimed to analyze the contribution of emotional labor (surface acting, deep acting) and organizational commitment (affective commitment, continuance commitment) to turnover intention and customer orientation of school foodservice dietitian. Methods: Our survey was administered to 393 school foodservice dietitian in the Busan area on February 11, 2014. Results: For verification of mean differences, the mean scores for surface acting, deep acting, affective commitment, and continuance commitment were found to be 2.53/5.00, 3.71, 2.88, and 3.57, respectively. The mean surface acting score was significantly different according to age (p<0.001), total length of career as a dietitian (p<0.01), school type (p<0.001), and employment status (p<0.05). The mean deep acting and turnover intention scores were significantly different according to age (p<0.001), total length of career as a dietitian (p<0.001), school type (p<0.001), employment status (p<0.001), and no. of meals served (p<0.001). The mean customer orientation score was significantly different according to age (p<0.05), employment status (p<0.01), and number of work hour (p<0.05). There was a positive correlation (p<0.01) between turnover intention and surface acting and continuance commitment, but a negative correlation (p<0.01) with deep acting and affective commitment. Also, there was a positive correlation (p<0.01) between customer orientation and deep acting, affective commitment, but a negative correlation (p<0.01) with surface acting. Affective commitment had a negative influence on turnover intention (${\beta}=-0.444$, p<0.001), but surface acting had a positive influence on turnover intention (${\beta}=0.110$, p<0.05). Conclusion: These results suggest that management of affective commitment is essential for decreasing turnover intention. Therefore, emotional labor and organizational commitment of school foodservice dietitians should be managed from the school foodservice organizational viewpoint of The Ministry of Education.

Purpose: This study was done to determine the risk factors for recurrent fallers (2+falls) compared to single fallers. Methods: Participants were 104 community-dwelling people 65 yr of age or older. The data were collected from June 1, 2008 to June 30, 2009 using the Residential Assessment Instrument-Home Care. Results: Over the past 90 days, 55.7% of the 104 participants fell once, and 44.2% experienced recurrent falls (2+falls). In comparison of recurrent fallers with single fallers, there were significant differences in scores on the following factors: gender ($X^2$=4.22, p=.040), age ($X^2$=5.74, p=.017), educational level ($X^2$=5.22, p=.022), living arrangements ($X^2$=35.02, p<.001), cardiovascular diseases ($X^2$=17.10, p<.001), hypertension ($X^2$=4.43, p=.035), diabetes mellitus ($X^2$=4.44, p=.035), glaucoma ($X^2$=13.95, p<.001), Minimal Data Set (MDS)-Pain (t=-2.56, p=.012), fear of falling ($X^2$=4.08, p=.034), reduced vision (t=-3.06, p=.003), MDS-activity of daily living (t=3.46, p=.001), MDS-Instrumental Activities of daily living (t=3.24, p=.002), cognition (MDS-Cognition Performance Scale) (t=3.40, p=.001), and 'difficulties entering and leaving the house' ($X^2$=4.53, p=.033). Conclusion: It is important to assess the risk factors for recurrent falls and develop differentiated strategies that will help prevent recurrent falls. Additionally, utilizing a standardized tool, such as RAI-HC, would help health professionals assess multi-variate fall risk factors to facilitate comparisons of different community care settings.

이미 국내에서도 '소리바다' 서비스 중지를 두고 오랫동안 논란이 있어왔고, 서비스 중지에도 불구하고 새로운 방식으로 서비스를 재개하면서 소리바다 논쟁은 새로운 국면을 맞고 있다. 논란의 핵심은 주요 음반사를 위시한 이익집단과 대다수 네티즌 사이의 논쟁을 비롯, 법적인 제재여부에 관한 법리 논쟁에 이르기까지 복잡한 양상을 띠고 있다. 국내의 이런 상황에 비춰 주목할만한 외국의 사례가 있어 소개한다.

In order to investigate the host range of Agrobacterium tumefaciens KU12 containing pTi-12, 28 species of dicotyledonous plants were infected with KU12, A136 without Ti plasmid and A348 containing pTi A6, respectively. KU12 and A348 induced tumor in 20 species and 14 species, respectively. This results showed that KU12 has a wide host range. Therefore, it was confirmed that KU12 and pTi-12 are very useful for developing plant vector system having a broad host range.

To investigate the radiation dose sensitivity in extremity radiatioin therapy depending on rice cultivar which have different size and shape of grains, plan results are compared that used rice bolus Korean and Thai rice. Phantoms that are each no bolus, Korean rice bolus, Thai rice bolus were used and prescribed 100 cGy to isocenter and checked the point dose of 12 points of interest of each phantoms. The meane dose are 103.57±1.98 cGy in Thai rice bolus using, 104.27±2.12 cGy in Korean rice bolus and 104.99±6.40 cGy in phantom without bolus. Dose distribution of Thai and Korean rice bolus differed significantly in Wilcoxon's Signed Rank test (p=.011). It has been confirmed that that the bolus using Thai rice, which has a small grain size, shows a more even dose distribution.
