Purpose: The aim of this study was to analyze Neonatal Intensive Care Unit nurses' behaviors while soothing newborns with bronchopulmonary dysplasia. Methods: An observational study was used to assess nurses' soothing behaviors. Data were collected from September, 2012 to March, 2013 using an audio-video recording system. Participants were eight babies and 12 nurses caring for those babies. After obtaining parental permission, the overall process of each episode from nurses' engagement in soothing to the end of soothing was recorded. Then a researcher interviewed each participating nurse. Data from 18 episodes were transcribed as verbal and nonverbal nursing behaviors and then categorized by two researchers. Results: There were 177 observed soothing behaviors which were classified with the five sensory-based categories (tactile, oral, visual, auditory, vestibular). Most frequently observed soothing behavior was 'Gently talking' followed by 'Removing irritant', and 'Providing non-nutritive sucking'. Nurses' perceived soothing behaviors were similar to the observed soothing behaviors except for 'Gently talking'. Conclusion: Nurses used diverse and mixed soothing behaviors as well as recognizing those behaviors as essential nursing skills. Nurses' soothing behaviors identified in this study can be used to comfort babies and to enhance their developmental potential in accordance with individual characterstics or cues.

Purpose: To investigate factors that may affect the method of feeding among preterm infants at 4 weeks after discharge. Methods: This study included 222 mother-infant dyads born before a gestational age of 37 weeks. The feeding method and general medical characteristics of the participants were assessed at 4 weeks after discharge using a structured questionnaire. Multinomial logistic regression analysis was used to examine which factors were associated with breastfeeding at home. Results: Of the 222 infants who qualified for the study, 71 (32.9%) continued to receive breastmilk at 4 weeks post-discharge. Multinomial logistic regression analysis showed that breastfeeding at 4 weeks post-discharge was associated with higher breastfeeding self-efficacy, vaginal delivery (experience), direct breastfeeding in the neonatal intensive care unit (NICU), gestational age between 30 and 34 weeks, and breastmilk consumption in the NICU. The following factors were associated with mixed feeding at 4 weeks post-discharge: being employed, having higher breastfeeding self-efficacy, and direct breastfeeding in the NICU. Conclusion: NICU nurses should provide opportunities for direct breastfeeding during hospitalization and support breastfeeding to enhance breastfeeding self-efficacy. These factors may help to ensure the continuation of breastfeeding after discharge. Moreover, factors that affect breastfeeding should be considered when providing interventions.

Purpose: This study aimed to identify the mental fitness, perspective taking, attitude toward the elderly, and quantitative encephalogram among caregivers. Methods: In this mixed method research, 14 female caregivers at an elderly care facility in Y city were participated from December 1st to December 31st, 2019. Structured questionnaires were applied to measure general characteristics, mental fitness, perspective taking, and attitude toward the elderly. Brain waves were measured by quantitative encephalogram in the prefrontal lobe. High frequency and high level of care tasks were analyzed using content analysis. Results: According to analysis of brain waves, caregivers experienced high level of physical strain & stress and psychological distraction & stress. Mental fitness (p<.05) and perspective taking (p<.001) were associated with attitude toward the elderly. Moreover, physical strain & stress was associated with psychological distraction & stress (p<.05, p<.001). High frequency and high level tasks were excretion and position change & movement care related tasks, respectively. Conclusion: These findings should be consider as an evidence for supporting care tasks based on concrete and objective understanding of caregivers using self-reported index as well as neurophysiological indicators including brain waves.

Purpose: This study was to investigate the influence of male nurses' gender role conflict and job satisfaction on their organizational commitment. Methods: Data were collected through a mixed method design using structured questionnaires (N=162) and a sequential qualitative interviews (N=8) from 2nd October, 2012 to 7th February, 2013. Data analysis included t-test, ANOVA, regression with SPSS/WIN 19.0 program and a qualitative thematic analysis. Results: Factors affecting participants' organizational commitment were job satisfaction and marital status which accounted for 36.2% of the total variance. In particular, low job satisfaction was not correlated with low organizational commitment despite lower job satisfaction. Three main themes connoting meanings of ambivalence were extracted from the data: desiring for the better future in spite of the current difficulty, strengthening their masculinity in tandem with complementing femininity in the midst of gender role conflict, leading their organization at times, and enduring hard work with responsibility for raising their family as a head of household. Conclusion: The findings indicate that male nurses' adjustment to the organization is controlled by ambivalence. It is essential to understand sociocultural contexts of male nurses as a minority in nursing fields for further research.

As a multidisciplinary study encompassing oceanography and history, we have attempted to reanalyze the course of a historical navel battle, Myungryang Naval Battle(September 16th, 1597 according to the lunar calendar) through hindcasting the paleo-tidal currents and -tides(PTC). Firstly, we conducted harmonic analysis using 6-month current data observed at Uldolmok and 1-year elevation data provided by Korea Ocean Research and Development Institute in order to understand their characteristics and to hindcast the PTC. Observation results show that Uldolmok, ~300m wide, relatively narrow channel, is characterized by a flood-dominant mixed mainly semidiurnal tidal regime induced by relatively-strong shallow water constituents, showing closely a standing wave type of tidal current. Further, we hindcasted PTC on the day of Myungryang Naval Battle. Our results were compared and discussed with results(time and speeds of maximum(flood and ebb) currents and high and low water times) of the previous studies estimated from different methods. Lastly, we reconstruct the course of the event of Myungryang Naval Battle recorded in the Admiral Sun-Sin Yi's War Diary(Nangjung Iigi in Korean) based on our hindcasting results.

Objectives : The research was conducted for the use of HT1 in the shoulder disease through correct acupuncture. Methods : (1) The contents were compared through reviewing literature. (2) The literature was studied in conjunction with the shoulder pathology and anatomical structures. Results : (1) The location of HT1 is described as 'in the axilla, over the axillary artery' in many literature, and the depth of HT1 is as shallow as 1 cm. The WHO standard also follows this. (2) There were many references to 'in the axilla, between the big muscles' in later generations, but there were mixed opinions about the exact muscle names. Based on the acupunctural review and the musculoskeletal study, the big muscles are considered to be 'Pectoralis major' and 'Latissimus dorsi'. (3) Among the muscles constituting the rotator cuff, applying acupuncture on HT1 is essential for 'Subscapularis m.'. Therefore, it is effective to stimulate 'Subscapularis m.' to a depth of 1.5 to 4 cm. Conclusions : The accurate acupoint of HT1 enables various uses of flank, armpit, shoulder and arm diseases as well as cardiopathy. Especially, it helps to treat the muscles through safe and effective acupuncture in shoulder rotator cuff disorder.

Periodically, harmful algal blooms (HABs) have occurred, with impacts on various areas including public health, tourism, and aquatic ecosystems, especially aquacultured and caged fisheries. To prevent or manage invasions of HABs into fish farms on an emergency basis, many methods have been proposed. Frequently over the past 30 years in coastal countries, treatments of clay and clay mixed with polyaluminum chloride (PAC) and chitosan have been tested for HAB-removal effectiveness in both the laboratory and the field. In Korea, yellow loess clay (hwangto) has been dispersed using electrolytic clay dispensers, both to decrease the amount of yellow loess clay's usage in containers and enhance HAB-removal efficiency. However, this emergency method has limitations, among which is the requirement for more effective controlling agents for field applications. Thus, in this paper, we review technologies for clay-based red tides prevention and control and their limitations, and, further, introduce next-generation algicidal technologies for the emergency protection of fish farms.

We propose a low temperature sol-gel ZnO/Ag nanowire composite thin film to fulfill low temperature and low cost requirements, which are essential criteria in future flexible electronic devices. In this proposed thin film, Ag nanowire plays the role of electrical conduction, and sol-gel ZnO provides a structural medium with a high visible transmittance. Low temperature restriction in the sol-gel fabrication process prevents sufficient oxidation of Zn acetate precursors, which were solved by a post-coating treatment with ultraviolet light irradiation. Composite thin film formation was performed by spin coating methods with a mixed precursor solution or in a sequential manner. We obtained an average visible transmittance larger than 85% and a sheet resistance smaller than $50{\Omega}/sq$. After optimization in a fabricated composite transparent conductive thin film with the thickness around 100 nm. Similar experimental demonstration in a flexible substrate (polyethyleneterephthalate) was successful, which implies a promising application opportunity of this technology.
