  • We are constantly hearing about the seriousness of food shortages in North Korea through various media reports. Recently, the severity of the problem has increased, and international organizations and relief organizations have become increasingly concerned. Due to the shortage of food and firewood, residents illegally cut trees in the mountains and, as a result, North Korea has become the third fastest-growing area of forest degradation in Asia. However, since North Korea cannot directly measure the extent of forest degradation, remote sensing techniques using satellite imagery have to be applied. The purpose of this study was to analyze the characteristics of forest change in North Korea, in order to understand the severity of the forest degradation problem. For this purpose, Landsat 5 TM and Landsat 8 OLI TIRS satellite images were acquired and classified. As a result, it was found that the forests have turned into wilderness in the Nampo City and Pyongyang municipalities, while the wasteland has changed into forests in the north of Yanggangdo. In addition, the total forested area of the whole region decreased by $4,166.22km^2$, the residential area decreased by $2,017.03km^2$, and the amount of agricultural land increased by $6,625.74km^2$, which is similar to the amount of forested area lost, although the difference in the overall area of the forests between 2017 and 2006 was small.

  • The purpose of this study is to evaluate the prevalence and related risk factors of problem drinking in the Korean adult population. Participants (n=7,867) aged 19 years or older were selected from the Korea National Health and Nutrition Examination Survey [KNHANES] of 2007-2008. Sociodemographic characteristics and AUDIT score were obtained from the KNHANES dataset. AUDIT scores were categorized into three groups, including low risk, intermediate risk, and high-risk alcohol drinking according to WHO guidelines. In this study, the prevalence of high-risk and intermediate-risk alcohol drinking were 12.2% and 21.0%, respectively. Adjusted mean AUDIT score was higher in men, younger individuals, as well as those with lower education levels and those that smoked. Results revealed that demographic variables, including sex, age, education level, and smoking, were important factors affected high-risk drinking. In particular, since smoking was the most significant risk factor, the adjusted odds ratio for high-risk drinking among participants that smoked was 4.78 [(95% confidence interval (CI)=3.75-6.10, p<.0001)]. This study suggests that men, younger age, low educational level, and smoking are the risk factors for a high-risk alcohol drinking.

  • In the construction of high-rise residential buildings in which the finishing works are done repetitively in each housing unit, the construction period and cost can be reduced, while maintaining the quality, if the work process is properly managed in order for the resources to be input continuously. Time management methods such as the Bar Chart, CPM and LOB are not appropriate, due to the difficulties involved in the diagraming of repetitive works and applying them to the project. The Tact method also has difficulties in maintaining a constant work flow and needs significant effort and cooperation from the subcontractors to allocate the resources consistently. Partitioning, base works for finishing, floor mortar plastering and the final finishing work are done sequentially in residential buildings projects, and there are many repetitive activities which differ in terms of the work method, work area and productivity. If these repetitive activities are synchronized or converged toward the last work area, the goal of process management can be achieved effectively. Therefore, a process planning method for the finishing works of residential building projects is proposed, which takes into consideration elements, such as the sequential relation between the activities in each housing unit and classification of repetitive works in terms of their management method, work area and production rate, for the continuous input of resources into the housing units.

  • The railway is a public transportation system that provides large-scale passenger transportation and service, whose reliability and safety is the top priority. The wiring of railway vehicles is classified into train control lines (train lines) and communication lines. The train lines are used for input / output signals related to vehicle driving and safety functions, and the communication lines are used for the input / output signals for passenger services such as broadcasting. In order to measure the reliability of railway vehicles, a train line is applied to the input / output interface of the control signals between the electric control devices in the vehicle, and there are many electromechanical devices such as relays and contactors for the control logic. In fact, since the vehicle control circuit is composed of several thousand contacts, it is difficult to check for errors such as contact failure, and it is impossible to check the real-time status, so a lot of manpower and time is required for regular maintenance. Therefore, we analyze the current state of the train line design of the electric equipment used for driving and services in domestic railway cars and propose three wiring reduction methods to improve it. Based on the analysis of domestic electric vehicles, it was confirmed that the wiring reduction effect is 35% or more.

  • The aim of this study was to provide fundamental information on the validity and credibility of the Korean geometric psychological assessment (GEOPIA) by investigating the degree of relation between the GEOPIA and the MBTI. Data was collected from 331 subjects aged 19 to 70, residing in Seoul, Gyeonggi Province, Jeolla Province, or Gyeongsang Province. Participants completed the GEOPIA and the MBTI during the period of May to September 2017. The study calculated Cronbach's ${\alpha}$ to verify the tests' validity and reliability through SPSS. For the relational analysis between the results of the tests, we conducted a one-way analysis of variance on the first group of the GEOPIA's personality types, and the Scheffe Test if significant relationship was found. The study found that the circle type was predisposed to ESFJ, the triangle type to ESTJ, the rectangle type to ISTJ, and S type to INFP. Higher scores of feeling (F) and perceiving (P) corresponded to circle and S types, thinking (T) and judging (J) for triangle and rectangle types, extroversion (E) for circle and triangle types, and introversion (I) for rectangle and S types. These confirmed the substantial relations between the GEOPIA and the MBTI.

  • This study was conducted to examine the nursing image types and characteristics of nurses perceived by nursing college students by applying the Q methodology and to manage effective nursing education and clinical education. The survey was conducted from May 15, 2017 to May 24, 2017, and the data collection for the Q population composition was based on in-depth interviews and literature review. First, nursing college students were searched for convenience and 158 statements were obtained based on open questionnaires and 64 statements extracted from in-depth interviews and after a literature review. To select the Q sample, Q population was categorized by taking several repeated readings. Five categories were developed from these processes: quality and role, social awareness, professionalism, uniqueness, and working conditions. The selected statements were reviewed and revised by experts and 35 Q samples were finally selected. Based on this, 46 students in one nursing college classified 35 Q statements, and analyzed data using PC QUANL program. The results of the study were as follows: 2) Type I-1: Job related anxiety, Type I-2: cold and professional, Type II-1: Complaint of treatment and Type II-2: Profession-Unacceptable. These results are expected to provide useful data for understanding the characteristics of nurses' images and provide data enabling development of image improvement strategies of nursing education and clinical education.

  • This study examined the factors affecting the readmission of patients with liver cirrhosis, and focused on self-care, social support, and drinking refusal self-efficacy. The subjects were 75 cirrhosis patients who were admitted to medium-sized hospitals at S-city for two months from May 2019 to June 2019. The data was analyzed with the SPSS (Version 25) program, and logistic regression analysis was performed on the factors affecting readmission. The results were self-care (27.49±0.53 out of 60), social support (52.80±16.44 out of 90), and drinking refusal self-efficacy (42.39±22.76 out of 80). The readmission method was classified into planned and unplanned admissions. Unplanned readmission was found to differ depending on the drinking experience (OR: 4.16) and the presence of complications (OR: 5.11) within a month of discharge rather than that of the planned readmissions, accounted for 19.7%. It will be very important to reduce the occurrence of complications by early management of patients with cirrhosis, and increase the drinking refusal self-efficacy, and so reduce unplanned readmission and prevent the progression and deterioration of cirrhosis. The drinking experience and the occurrence of complications can be reduced through interventions that increase self-care, social support, and drinking refusal self-efficacy. Nursing interventions are needed to prevent patients with cirrhosis from drinking and to manage the complications due to relapse into alcoholism.

  • Purpose: Organophosphate insecticide poisoning can have clinically fatal results. This study aimed to evaluate the relationship between the neutrophil/lymphocyte ratio (NLR) and the occurrence of death in patients with organophosphate insecticide poisoning. Methods: For this retrospective study, data on patients with organophosphate insecticide poisoning who visited the emergency room between January 2008 and November 2018 were collected. The NLR was measured at the time of arrival in the emergency room. The patients were divided into survival and death groups. Results: Overall, 150 patients were enrolled: 15 (10%) in the death group and 135 (90%) in the survival group. In the univariate analysis, the following variables were significantly different between the two groups: age, white blood cell count, amylase level, creatinine level, Acute Physiology And Chronic Health Evaluation (APACHE) II score, and NLR. In the logistic regression analysis of variables with significant differences in the univariate analysis, there were significant differences between the two groups with respect to age, APACHE II score, and NLR. The NLR was significantly higher in the death group than in the survival group (20.83 ± 22.24 vs. 7.38 ± 6.06, p=0.036). Conclusion: High NLR in patients with organophosphate insecticide poisoning may be useful in predicting mortality.

  • In this study, we evaluated degree of importance of e-marketplace solution selection factors. Factor analysis was conducted to find out relationships among various variables which come from literature survey. The result shows that 16(sixteen) -selection variables regarding solution characteristics could be grouped into four areas 'flexibility', 'ease of use', 'security', and 'economy'. And 11(eleven) selection variables regarding to vendor characteristics could be grouped into three areas, 'vendor's support', vendor's general situation', and 'vendor's business accomplishment`. Through various analysis, we found important factors for 3 types of operational companies, buyer-biased, seller biased and neutral. 'Security for data item' was showed as the most important factor for all kind of B2B operational companies. For buyer-biased companies, additional supporting manpower, solution education, and educational cost are shown to be more important factors than others. Place of education, education hours and education level are important for 'Neutral' companies. And the factor 'market share of vendor' are important for 'seller biased' companies.
