Through COVID-19, the importance of supply chain management of raw material minerals has been maximized. In particular, supply chain management is important for rare metals, which are difficult to manage demand and supply, in order to secure raw materials for the parts and materials industry that Korea is actively promoting. In this study, a system was established and evaluated to select Critical minerals that need to respond to Korea's industrial structure and global risks by quantifying tangible and intangible risk factors. Global Supply Concentration, Supplying country risk, Policy Social Environment Regulation, Domestic Import Instability, Risk responsiveness, Market Scale, Demand Fluctuation and Economic Importance were evaluated as evaluation indicators. The degree of risk and risk impact were quantitatively measured using the criticality matrix-criticality level. After evaluating 40 types of minerals used in domestic new growth businesses, 15 types of Critical minerals(Li, Pt, Co, V, REE, Mg, Mo, Cr, Ti, W, C, Ni, Al, Mn, Si) in Korea were selected. The results are expected to be used to establish policies to strengthen resource security and to make decisions to form a company's raw material portfolio.

A Reference Sound Source (RSS) is an important standard device employed in measuring sound power. The specifications of RSS is specified in international standards, and it is classified as a major calibration item in the field of acoustic metrology. Since the output power of RSS is affected by the supply voltage, each country needs to secure its own calibration service system. In this study, a procedure for calibrating a RSS is established based on the reverberant room conditions and uncertainty evaluation is conducted. Basically, the calibration procedure can apply a precision measurement process of acoustic power, and here, the measurement method using the reverberation chamber of ISO 3741 is applied. For this purpose, a measurement system is constructed, measurements are conducted with two types of RSS, and measurement uncertainty is evaluated. Through measurement examples, it is confirmed that the non-uniformity of the sound pressure distribution in the reverberation room and the volume measurement uncertainty contributed significantly to the overall uncertainty. Additionally, the influence of input voltage is experimentally examined to examine the uncertainty contribution that can be reflected in acoustic power measurements.

The average smoking rate for Adults' in our country is 40.6% : It is 74.2% for men and 5.0% for women. Particularly, the smoking rate for men is reported higher than that of men in U.S.A. or Japan. Since the first report on the association between smoking and cancer appeared, 370 thousand smokers have succeeded in smoking cessation and over 90% of them have responded that they depended on a self-help smoking cessation approach. Despite this positive evidence about self- help approaches for smoking cessation, most studies on smoking cessation have focused on evaluation of formal treatment programs that are provided by clinics. Reports on the smoking cessation process used by smokers in our country could not be found. However, it is believed that the situation in our country would be quite similar to that in U.S.A. as far as approaches to successful smoking cessation are concerned. This study was conducted to classify the smoking stage to which they smoker belong and which changing mechanisms could be included at each changing stage (precontemplation stage, comtemplation stage, action stage) with a sample of 155 college students between 20 and 29 years old. And it also identified which variables related both to smoking pattern and to health, which ones were significantly discriminating in the changing stages. From the results of the data analysis it was found that Self-Determination is the most influential variable as one of the changning mechanisms which can discriminate three changing stages. And as the next significant mechanisms were Reinforcement, Dramatic Relief, Cognitive Restructuring, Helping Relationship, and Information Management in that order. Among variables related to the smoking pattern, years of regular smoking, whether smoking is continued or not even when they are sick, the number of attempts to stop smoking, number of cigarettes smoked per day, and whether they have smoked over 100 cigarettes up to now, but not the time of the first cigarette after waking-up, were the significant factors to descriminate changing stages. It was confirmed that among variables related to health that, perceived control for health, confidence of health maintence ability, and self confidence in smoking cessation, were significant variables in determinating changing stages. The most influential variables among them was self-confidence in smoking cessation. Conclusively, it was shown that smoking cessation is the process of attempting to change smoking habits through the various changing processes. Also it can be shown that a few factors smoking habit, self-confidence of smoking cessation, and belief in self control of his /her health, were influential in discriminating the changing stages of the smoking habit.

The purpose of this study is to analyze the major issues discussed among Parties and provide a framework for predicting the agreements on those issues, prior to the final negotiation on a new legally-binding agreement on climate change adaptation in the United Nations Framework Convention on Climate Change (UNFCCC). The analyses of documents, adaptation actions, and work of the Ad Hoc Working Group on the Durban Platform for Enhanced Action (ADP) under the UNFCCC informed that the adaptation issue has primarily been focused on the support of developed country Parties for the adaptation of developing country Parties following the principle of the Convention, Common but Differentiated Responsibilities and Respective Capabilities (CBDR-RC). Three-year work of the ADP acknowledged the major issues on adaptation in the new climate agreement, which would be categorized as long-term and global aspects, commitments/contributions/actions, monitoring and evaluation, institutional arrangements, and loss and damage. A final agreement on each issue could be predicted by setting a zone of possible agreement in-between the two extremes of developing and developed country Parties and considering three major elements affecting the Parties' positions, national priority, adaptation action, and social expectation, which are proposed in this study. The three major elements should be considered in a balanced manner by Parties to draw a durable agreement that will enhance global adaptation actions from a long-term perspective. That is, the agreement needs to reflect adaptation actions occurring outside the Convention as well as social expectations for adaptation. It is expected that the new agreement on climate change adaptation, from a long-term and global perspective, would be an opportunity to reduce vulnerability and build resilience to climate change by incorporating global expectations.

As Korea declared that the entire country is free from ISA (Infectious salmon anaemia) based on the OIE aquatic code in 2019, it is necessary to improve the import quarantine system that meets the level of ISA management in Korea. Currently, Korea imports Atlantic salmon and rainbow trout from countries which have history of ISA outbreak such as Norway and the United States, so there is a constant possibility that trade with these countries will bring ISAV (Infectious salmon anaemia virus) into Korea. Therefore, some amendments to the Aquatic Life Diseases Control Act (ALDCA) are needed to prevent the entry of ISAV into the Korea through international trade. The amendment to the ALDCA should contain a list of countries, zones or compartments that the Korean competent authority has allowed or banned imports of ISA-susceptible fish. In addition, the subordinate statutes or administrative rules of the ALDCA need to be revised so that on-site inspections/audit can be conducted for the evaluation of the ISA management system in exporting countries. After the revision of the subordinate statutes or administrative rules, it is necessary to strengthen the present import conditions in line with those that meet the level of ISA management in Korea. As for the strengthened import conditions, the competent authorities of exporting countries must export only salmonid fish produced in zones or compartments declared freedom of ISA to Korea, and must prove through lab-testing that ISAV should not be detected in the fish exporting to Korea. In addition, official veterinarians/fish health professionals of the exporting country should check the health status of the fish within 72 hours prior to export. Also, competent authorities of the exporting countries must attest that fish storage containers and water, ice and other equipment used for transportation should be cleaned and disinfected to avoid contamination with pathogens, including ISA. Therefore, the proposed measures presented here will further improve the current import condition for salmonid fish and assist decision-making on strategies to reduce the risk of ISA introduction into Korea. Also, it is expected to contribute to maintain the status of ISA-free country.

Background and objective: The problem that follows the increase of dementia patients is the burden of caregivers caring for dementia patients. The purpose of this study was to examine the effects of horticultural therapy programs improving the quality of life and reducing the depression and burden of caregivers of the elderly with dementia. Methods: In this study, 19 caregivers of the elderly with dementia were selected, and the experiment was conducted by dividing the control group (n=9) and the experimental group (n=10) by random distribution. The experimental group was given eight horticultural therapy programs twice a week for a total of 4 weeks. Subjects were assessed using the depression(CES-D), quality of Life (WHOQOL-BREF), and care burden scales. The evaluation results were verified at a 95% significance level using descriptive statistics, the Mann-Whitney U test, and Wilcoxon signed-rank test. Results: In the case of depression, the control group's score tended to increase, and the experimental group's score appeared to decrease, but it was not a statistically significant change. In the quality of life, the control group was not statistically significant, but scores decreased overall. On the other hand, in the experimental group, the general quality of life increased significantly from 11.60 to 14.20 points (p = .02), and the total quality of life increased to a marginally significant level from 61.59 points to 68.85 points (p = .059). In the post-test of the total care burden score, a marginally significant difference was found between the control group (94.44 points) and the experimental group (82.50 points; p = .079). Conclusion: This study confirmed the applicability to reduce the burden of caregiving and improve the deterioration of quality of life of the caregivers. In particular, the results will serve as an opportunity to confirm accessibility in a new way to support the caregiver of dementia patients by demonstrating the applicability of horticultural therapy at a time when problems such as the burden of supporting the caregiver are emerging as social problems.

The objectives of this study were to i) investigate genetic performance for linear type traits of individual Holstein dairy cows, especially focusing on comparative traits, and to estimate genetic variances for these traits using actual data, and ii) compare genetic performance and improvement of progeny by birth country of the cows. Linear type traits defined with five comparative traits on this study were general stature composite (GSC), dairy capacity composite (DCC), body size composite (BSC), foot and leg composite (FLC), and udder composite (UDC). These traits were scored from 1 to 6 with 1 = poor, 2 = fair, 3 = good, 4 = good plus, 5 = very good and 6 = excellent. Final scores (FS) were also included in this study. Data used was collected from the years 2000 to 2004 by the Korea Animal Improvement Association (KAIA). Only data of more than five tested cows by herd appraisal date and by sires having more than ten daughters were included to increase the reliability of the data analyses. A total of 30,204 records of the selected traits, which was collected from 26,701 individuals having pedigree information were used. Herd appraisal date, year of age, lactation stage (grouped by month), and time lagged for milking (in hours) were assumed as fixed effects on the model. Animal additive genetic effects considering pedigree relationship and residual errors were assumed with random effects. Year of age at appraisal date was classified from one to nine years of age, assigning the value of nine years of age for animals that were greater than or equal to nine years of age. From our results, the estimate for heritability was 0.463, 0.346, 0.473, 0.290, and 0.430 on GSC, DCC, BSC, FLC and UDC, respectively. The estimate for FS heritability was 0.539. The greatest breeding values for GSC were estimated for Canada, with the breeding values for American lines increasing for 10 years starting in 1989 but tending to decrease after that until 2004. For DCC, the breeding values for American and Canadian lines showed similar patterns until 1999, after which the breeding values for the American lines declined sharply. For BSC, data from Korea, Canada and the USA followed similar trends overall except when the breeding values of the American lines decreased starting in 1999. Overall, the methods used to evaluate genetic performance in this study were acceptable and allowed for the discovery of differences by country of genetic origin, likely due in part to the American use of selection indexes based primarily on milk yield traits until methods for evaluating other traits began to emerge.

The purpose of this study is to suggest directions to improve engineering education and the assessment system of our country. For this object, the present situation of engineering education and assessment system in Korea have been reviewed and next, for those of study, the research papers and publications about the environment of college education are analyzed. Finally, an improved assessment system is suggested. It has already passed out for 6 years since execute the accreditation for engineering education in our country now, but essential point for step in accreditation for engineering education is how the evaluator can make the outcomes of studying. This is not a new terminology that is deformed according to special quality of college of engineering which prefer out-come based of study than process based of study to mean accomplishment in engineering education. The evaluation that estimate program is a skill, but an assessment method is not the meaning of individual student accomplishment also, it is the measure of validity estimation that should be estimate ability of students who complete program by proper authority. However, a new evaluation strategy that assess student outcome by person who consider the objectivity and validity, reliability should be develop for decision making of ABEEK. It is an original, private discussion for assessment strategy about the method for student learning outcomes assessment.

This is a research on general evaluation of the nursing profession which is a professional job, a suitable calling to women and is developing academically day by day. The author gave some questions to the patients, doctors, people, student nurses-themselves and got the following results; (A) General concept about nursing profession A nurse is a member, of a medical team who works for people′s health promotion(50.8%). The reason that the nursing profession is a good one is that it is a rewarding job to care for sick patients(78.9%). The spirit is the most important factor for the nurse(84.8%) and the nursing profession is a suitable calling to women (76%). The description of nurses as "The angels in white dress" is an appropriate one (44.6%) or only a beautiful expression(47.4%) (B) Nurses as actually seen by doctors and patients. They work only obligatorily (47.8%)-Doctors They try to relieve, the patient′s physical discomforts in all sincerity (65.6%), also they to decrease the patient′s mental apprehension (56.7%). (C) Satisfaction in the nursing profession. Nurses satisfaction in the nursing profession is general(68.8%) and student nurses satisfaction in selecting nursing is fulfilled (50.9%). One reason for dissatisfaction among nurses and student nurses is people's failure to understanding the nursing profession(40.1%), One reason for satisfaction is that it is a rewarding job caring for sick patients(35%). (D) Is the nursing professional job? People think the nursing profession is a professional job like doctors or lawyers (60.2%). (E) Are they academic? People think the nurses are academic(37.8%) but nurses read only interesting items in the "Journal of Korean Nurse"(67.7%). (F) Opinions about nurses′going out of the country. Doctors and nurses agree that after 1-2 years′experience in this country(78.5%) and student nurses want to go out where there is on opportunity(73.1%). Student's purpose of going out is to enrich their stock of information(71.3%), doctors think, it is for training in nursing knowledge and skills (47.8%). (G) Opinions about nurse′s social affairs. They want nurses to be controlled(44.4%) and also think that the nurse's demonstration in the National Conte. was reasonable (36.3%). (H) Would you make your daughter a nurse?
