Securing "a competent worker" who can create profit from knowledge is an important keyword for a company to survive in the keen competition of knowledge-based society. In the environment where we must constantly emphasize change and innovation, the members of higher emotional competence an organization has, the more actively it is likely to cope with changes (Park, Choi, & Lee, 2006). Also, studies have been released that the effective organizational learning has positive influences on Organizational Effectiveness (Lee, 2007; Lee, 2010; Chan et al., 2003). This study, in the periodical situation where the importance of major talent management is emphasized, is aiming to verify relationships between emotional competence, organizational learning, job attitudes and organizational loyalty of organization members aimed at employees of a company and to present a desirable direction of corporate education for developing the core competence of human resources. Organizing members of a company for a population were selected as the subject of this study, and self-reporting survey was done by the employees of SA company and SS company, etc. according to both a convenience sampling and a purposive sampling method. The total 61 questions of research tool consist of 16 questions about emotional competence (Wong & Law, 2002), 18 about organizational learning (Lee. 2007; Song & Choi, 2009), 13 about organizational effectiveness (Korea Labor Institute, 2006; Mayer & Allen, 1990) and 9 about organizational loyalty of organization members (Lee, 2012), etc. As a result of analyzing a study of theoretical background about the relationship between each variation factor and a hypothetical research model which had been designed through the consideration of preliminary study via a series of procedure, the study confirmed the relationship and importance of organizational effectiveness (job satisfaction, organizational commitments) related to an performance of organization, and emotional competence and organizational learning that affects organizational loyalty. Emotional competence of perceiving others`` emotional components are highly required when we need to communicate with colleagues or customers with diverse tendencies and distinct cultural backgrounds. Also, in order to develop organizational effectiveness and organizational loyalty of organization members, it is needed to cultivate emotional competence and organizational learning skills. Therefore, emotional competence should be included in the important screening criteria during hiring process of the competent and most of all, in order to manage and nurture the competent people of a company, corporate education programs with long-term viewpoints should be design and operated for higher emotional competence and learning skills of organization members.

This study was conducted to investigate the effects of TMR on in vitro rumen fermentation and methane production of goat with different forage sources. The experiment was arranged 4×2 factorial design. The different forage sources were rice straw (RS), Italian rye grass (IR), timothy (TI) and alfalfa (AL), respectively. There were two different forage : concentrate ratios such as 20:80 (20) and 50:50 (50), respectively. Therefore, totally 8 treatments were used: 1) RS20, 2) RS50, 3) IR20, 4) IR50, 5) TI20, 6) TI50, 7) AL20, and 8) AL50, respectively. The rumen fluid of goat was collected from the slaughterhouse. For fermentation parameters, ruminal pH, total gas, methane, hydrogen, ammonia nitrogen, and volatile fatty acid were determined. The pH values were within an optimal range across all treatments. Total gas productions at TI20 and AL50 were significantly greater than others (p<0.05). Methane production was significantly lower in TI and AL compared with other treatments (p<0.05). The relatively high dietary NDF content in treatments showed significantly lower methane production (p<0.05). Significant alterations treatments were detected at ammonia nitrogen concentration according to the ratio of forage : concentrate (p<0.05). AL treatment showed greater total volatile fatty acid production compared with other treatments (p<0.05). Therefore, the present study suggests that both Timothy and Alfalfa could be recommendable forage sources for goat based on results with volatile fatty acid as an energy source and methane as an index for energy loss and environmental issues. Also, the 50:50 (forage : concentrate) ratio would prefer to 20:80.

As of September 3, 2022, 5,388,338 coronavirus disease 2019 (COVID-19) cases and 46 deaths (3 in 2021 and 43 in 2022) were reported in children ≤ 18 years in Korea. Cumulative confirmed cases accounted for 67.3% of the population aged ≤ 18 years and case fatality rate was 0.85/100,000. Among 46 fatal cases, 58.7% were male and median age was 7 years. Underlying diseases were present in 47.8%; neurologic diseases (63.6%) and malignancy (13.6%) most common. Only four had history of COVID-19 immunization. COVID-19 associated deaths occurred at median 2 days from diagnosis (range: −1 to 21). Among COVID-19 deaths, 41.3% occurred before admission; 2 before hospital arrival and 17 in the emergency department. Among children whose cause was documented, myocarditis, respiratory and multiorgan failure were most common. COVID-19 associated death was seen early after diagnosis in children and public health policies to provide access to medical care for children with COVID-19 are essential during the pandemic.

Since the 1970s regulations against the pollution of drinking water have been introduced in Lake Paldang watershed area. To understand the effects of water environment management policies and the impacts of climate changes on Lake Paldang, a long-term comprehensive study of this watershed and the changes in its water environment is required. In this study, we analyzed changes in the weather, hydrology, sources of pollution, water quality, and algal development from 2000 to 2015 year based on the statistical data provided by several national information systems. While the population and amount of sewage in the Lake Paldang watershed increased by about 1.5 times, the amount of animal manure showed a decreasing trend during the same period. The wastewater also increased by about 1.5 times while the amount of water intakes rose by about 1.14 times. The water quality in front of the Paldang Dam, which is the representative monitoring site of the Lake Paldang, was stable. The annual average BOD concentration remained within 2 mg/L, which is a “Good (lb)” level according to the environment standards of Republic of Korea. The development of phytoplankton and harmful cyanobacteria were largely influenced by meteorological factors.

바이오리액터 매립장에 대한 전기비저항 탐사 기법 고찰

심낙종 ( Nakjong Sim ),전은정 ( Eunjeong Jeon ),이재일 ( Jaeill Lee ),류돈식 ( Donsik Ryu ),김윤희 ( Yoonhee Kim ),김철희 ( Chulhee Kim ) 한국폐기물자원순환학회(구 한국폐기물학회) 2016 한국폐기물자원순환학회 추계학술발표논문집 Vol.2016 No.-

수도권매립지의 경우 하수슬러지 등 유기성 폐기물의 직매립금지로 인하여 매립되는 폐기물의 건조화가 심각한 상태이다. 현재 매립지 내부 함수율은 미생물에 의해 분해활동이 원활히 이루어지는 45%에 크게 못미치는 30% 수준으로 나타났다. 이같은 현상은 비단 수도권매립지에 국한된 문제가 아닌 전국 매립지에 해당되는 현상일 것이다. 또한, 매립종료 후 최종복토 후에는 우수의 유입도 차단됨에 따라 매립지 내부 건조화 문제는 더욱 더 심화되는 것은 자명한 사실이다. 이와같이 건조화가 심화되면 폐기물분해 지연에 따라 매립지 사후관리 기간은 더욱 길어지게 되며 그만큼 각 매립지 관리주체들의 비용부담은 증가하게 될 것이다. 정부는 이러한 문제점의 해결을 위해 금년 4월 폐기물관리법 시행규칙을 개정하여 매립지 내부로 침출수를 재순환할 수 있는 침출수매립시설환원정화설비 관련 규정을 시행하였으며, 침출수를 매립지로 재순환하여 매립지 건조화 문제를 최소화할 수 있는 방안을 마련하였다. 비록 침출수외에 폐수 같은 다른 수분 공급원의 재순환까지 허용하는 적극적인 수단은 아니지만, 침출수를 재순환함에 따라 매립지 건조화가 심화되는 것은 방지할 수 있을 것으로 기대된다. 본 연구에서는 침출수 재순환에 따른 매립지 내부 수분 분포파악을 위하여 전기비저항 탐사를 수행하여 매립지 내부의 수분분포 특성 파악을 위한 적정 탐사기법을 개발하고자 하였다. 일반적으로 전기비저항 탐사는 지하 매설물이나 지질현황 파악을 위하여 쓰이며, 저수지 등의 제방 안정성 파악에도 많이 사용되고 있다. 그러나 매립지의 경우 다양한 폐기물들이 매립되어 있어 토질이나 저수지 제방과 같이 매질이 균질한 상태가 아닌, 매우 불균질한 상태이며, 계절에 따른 온도변화, 중간 복토층에 따른 비저항 탐사 값의 간섭현상 등 다양한 변수가 존재하여 결과값의 해석에 많은 어려움이 있다.

Risk Factors for Sudden Death Within 2 Days After Diagnosis of COVID-19 in Korea

Choi So Young,Ryu Boyeong,Lee Hyun-Ju,Kim Dong-Hwii,Shin Eunjeong,Kim Seong-Sun,Kwon Donghyok 대한의학회 2023 Journal of Korean medical science Vol.38 No.27

Background: We aimed to analyze the risk factors for sudden death after diagnosis of coronavirus disease 2019 (COVID-19) in South Korea and to provide evidence for informing prevention and control interventions for patients at risk of sudden death. Methods: We included 30,302 COVID-19 related deaths registered in the patient management information system (Central Disease Control Headquarters) between January 1, 2021, and December 15, 2022. We collected their epidemiological data recorded by the reporting city, province, or country. We performed multivariate logistic regression analysis to identify risk factors for sudden death after diagnosis of COVID-19. Results: Among the 30,302 deaths, there were 7,258 (24.0%) and 23,044 (76.0%) sudden and non-sudden deaths, respectively. Sudden death means a person who died within 2 days of diagnosis and who did not receive inpatient treatment. Underlying condition, vaccination status, and place of death were significantly associated with the survival period in all age groups. Moreover, region, sex, and prescription were significantly associated with the survival period only in certain age groups. However, reinfection was not significantly associated with the survival period in any age group. Conclusion: To our knowledge, this is the first study on the risk factors for sudden death after a diagnosis of COVID-19, which included age, underlying condition, vaccination status, and place of death. Additionally, individuals aged < 60 years without an underlying condition were at high risk for sudden death. However, this group has relatively low interest in health, as can be seen from the high non-vaccination rate (16.1% of the general population vs. 61.6% of the corresponding group). Therefore, there is a possibility for the presence of an uncontrolled underlying disease in this population. In addition, many sudden deaths occurred due to delayed hospital visits to continue economic activities even after the onset of COVID-19 symptoms (7 days overall vs. 10 days average for the group). In conclusion, ‘continued interest in health’ is a key factor in avoiding sudden death in the economically active group (under 60 years of age).
