Patients experiencing out-of-hospital cardiac arrest (OOHCA) during the weekend are less likely to survive to hospital admission than those experiencing OOHCA on weekdays. We aimed to determine whether the survival rates of in-hospital cardiac arrest (IHCA) were lower on weekends than on weekdays. We comprehensively reviewed the records of patients who experienced IHCA at CBNUH between 2018 and 2020. A total of 861 IHCAs occurred during the study period; these data included recurrent IHCA cases, as some patients experienced more than one IHCA. Of these, 739 IHCA cases were included in the survival analysis, and the survival rate was 65.2%, which is higher than the rate reported in a previous study. There were no differences in the survival rate between weekdays and weekends. Additionally, the time of day at which IHCA occurred and pre-IHCA intubation status did not affect survival. Patients in wards were less likely to survive than those in intensive care units (60.0% vs. 66.0%). Although pre-IHCA intubation did not show any added value in preventing sudden cardiac arrests, meticulous patient care and monitoring in terms of intra- or extrapulmonary oxygen therapy is needed, as is the promotion of cardio-pulmonary-cerebral resuscitation (CPCR) equipment availability and quick rescuer responses for patients with IHCA. Our findings may be of value in improving CPCR guidelines and monitoring patients at risk of IHCA.

This study aims to study factors affecting level of Korean language proficiency for North Korean Refugee Adolescents dwelling in Korea. 30 North Korean Refugee Adolescents were asked to answer three different questionnaires designated to investigate Korean language proficiency, Acculturative Stress and demographic background. This study adopts altered TOPIK for the evaluation of Korean language proficiency, and focuses on finding out the relationship of Korean language proficiency with sexuality, age, years of Korean study, and duration of dwelling in China. The SPSS for windows 15 was used for the statistical analysis. Acculturative Stress Scale was measured with the ASIS that was developed by Sandhuand Asrabadi(1994) and Proficiency Test that was selected by TOPIK (Test of Proficiency in Korea) session 22, 23. Cronbach for Acculturative Stress Scale was 0.898. Internal consistency reliability for Korean proficiency test was 0.897. The result shows that learning methods(Korean friends or books), duration of stay in China, Korean use, learning period, age, and gender have significant relationship with level of Korean proficiency, especially periods living in China has more significant relationship with the proficiency. The result from this study helps to recognize factors affecting level of Korean language proficiency. Specifically, the Korean proficiency of North Korean Refugee Adolescents who live in Korea has a close relationship with Acculturative Stress Scale. These facts indicate that not only the Korean education are required to effectively increase the Korean education itself, but also developing the competency of Cultural Acculturation are needed to be followed up as well for North Korean Mission.

This study aims to study factors affecting level of Korean language proficiency for Korean Missionaries' Kids (MK) dwelling in Turkey. 45 Korean MKs were asked to answer three different questionnaires designated to investigate Korean language proficiency, cultural identity and demographic background. This study adopts altered TOPIK for the evaluation of Korean language proficiency, and focuses on finding out the relationship of Korean proficiency with sexuality, age, age at immigration to Turkey, years of Korean study, self-recognition of cultural identity, cultural identity of Korea, and cultural identity of Turkey. The SPSS for windows 17was used for the statistical analysis.Ethnic Identity Scale was measured with the KAEIS that was developed by Ahn(1999) and Proficiency Test that was selected by TOPIK (Test of Proficiency in Korea) session 19, 20. Cronbach  for cultural identity of Korea was 0.823 and Cronbach  for cultural identity of Turkey was 0.691. Internal consistency reliability for Korean proficiency test was 0.891. The result shows that cultural identity of Korea and age at immigration to Turkey have significant relationship with level of Korean proficiency, especially age at immigration to Turkey has more significant relationship with the proficiency. The result from this study helps to recognize factors affecting level of Korean language proficiency. Especially, the Korean proficiency of MKs who live in Turkey has a close relationship with Korean cultural identity.These facts indicate that not only the Korean education are required to effectively increase the korean education itself, but also developing the pride of being Korean are needed to be followed up as well.

As one of study efforts to develop a food product that can satisfy the taste of modern people and increase the usage of the popular local product of walnut in the region of Chunan, the current study developed a no sugar added functional walnut-sulgi. The walnut-sulgi was manufactured by adding walnut powder into typical sulgi rice cake. While manufacturing the walnut-sulgi rice cake, the health beneficial sugar alcohol ingredient of sorbitol was added instead of commonly used sugar to specialize the walnut-sulgi as a functional rice cake. As the result of such effort, a soft and moist walnut-sulgi was produced. The color of the newly developed walnut-sulgi is white and has a pleasing taste, and its consumer acceptability was higher than the sugar added walnut-sulgi by showing much soft sweetness and textural properties. Considering the facts that sorbitol has a lower glycemic index (GI) than sugar and the content of unsaturated fatty acids that are insufficient in rice cake could be increased, the newly developed sorbitol added walnut-sulgi is thought to be an appropriate functional rice cake that can attractively appeal to obesity and diabetes concerning modern people.
