Objectives: The purpose of this study is to assess the effect of electroacupuncture for treating postpartum hypogalactia. Methods: We searched 9 databases on May, 2022, which contained four English, two Chinese, one Japanese, and two Korean databases. Randomized controlled trials (RCTs) were eligible. Measurement of outcome included total effective rate, lactation amount, serum prolactin level, and degree of breast fullness. The risk of bias was assessed by two independent authors using the Cochrane risk of bias tool. Results: 101 trials were screened, 5 RCTs were finally selected. Number of participants per study ranged from 56 to 273. The treatment group was effective of improving total effective rate, lactation amount, serum prolactin level compared with control group, and the result was stastically significant. The quality of the evidence for specific comparisons ranged from low to high. Conclusions: Included studies showed that electroacupuncture on acupoints related to lactation would be effective way to increase milk supply among mothers who are suffering from postpartum hypogalactia. In the future, further high-quality RCTs are needed to prove effectiveness of electroacupuncture for relieving hypogalactia with low risk of bias.
Background: This study was aimed at reducing depression and improving the quality of life and oral health of the elderly Koreans by elucidating the effect of depression on their life quality and oral health. Methods: Original data from the 8th National Health and Nutrition Survey (2019) were analyzed and implemented. The elderly (age≥65years) Koreans were enrolled. The oral health status was determined using the Decayed, Missing, Filled Teeth (DMFT) index and subjective self-report. The quality of life was quantified as the sum of score of each item in the Euro Qol-5 dimension (EQ-5D) and Health-related Quality of Life Instrument with 8 Items (HINT-8). The t-test, one-way analysis of variance, correlation analysis, and multiple regression analysis were performed to statistically compare the quality of life, oral health status, and oral health status according to the depression status. Results: EQ-5D and HINT-8 scores differed significantly with the history of depression, current depression, stress perception, depression for 2 weeks, and annual suicidal intention (p≤0.05). The DMFT index score differed significantly with the depression diagnosis and depression for 2 weeks (p≤0.05). EQ-5D, HINT-8, and DMFT index differed significantly with all oral health behavior variables (p≤ 0.05). Conclusions: The results of this study could serve as a basis to formulate oral health programs for the elderly to reduce depression and improve the quality of life.
The purpose of this study was to improve the dietary attitudes of elementary students through nutrition labeling education. A class of fifth-grade elementary students was selected and educated for basic nutrition and reading of nutrition labeling for 8 weeks by using education materials from the KFDA. After the education, the children were subjected for the practice of reading nutrition labeling during winter vacation, and the changes in their dietary attitudes and practice were measured by using questionnaires for children and their parents along with measuring physical changes. The results were as follows: The level of nutritional knowledge was improved significantly after the education (p < 0.05). Nutrition labeling education Increased the children's frequency of reading nutrition labeling from 34.2% to 57.9% while purchasing processed foods (p < 0.05), and 92.1% of the children answered that their dietary attitudes improved by nutrition labeling education. However, no improvement in physical measurements was observed after education. This result suggested that 8-week of education were not enough to show the improvement in physical measurements, and long-term and repeated education is necessary. After the education, most children answered that they recognized the benefit of reading nutrition labeling and they would read the nutrition labeling when purchasing processed foods. Parents also recognized the necessity of nutrition labeling education in school and suggested the need of nutrition labeling be easy to read. The above results suggested that nutrition labeling education is an effective way for improving dietary attitudes of children.

The essence of a natural stream restoration project is providing habitats for various creatures in terms of the stream's environmental function. This research suggests the problems of natural stream restoration project by studying streams in terms of habitats for creatures and reviewing the national and international cases on existing natural stream restoration project. As a solution for the above, this research suggests a preservation method for biotope of upper stream areas focusing on the fish biotope area considering the ecological characteristics and preservation value of the respective stream so that the stream can be preserved as habitats for creatures. The research was carried out on Cheonglimli Baekcheon region which is an upper stream area of Buan-Dam located in the public park in Byunsanbando, Buangoon, Jeonlabookdo. We suggest the preservation method based on the habitat environment and keystone species of fish. The habitat environment evaluation was carried out mainly being divided into three groups namely, habitats and surrounding environment, reservoir's features and fish way and the diversity of fish. By improving the problematic elements discovered through such evaluation, it tries to improve the biotope of the stream and continuously preserve the stream. In addition, in order to restore the stream as habitats for various creatures, this research suggests to select keystone species which are suitable for the stream environment and restore the habitats based on the keystone species rather than restoring habitats for all species. Fish not only plays the role of a consumer of Epilithic algae and water beetles but also plays an important ecological role as a food for birds or small mammalia. If such ecologically important biotope for fish is preserved, the ecological environment of the stream will be maintained more stably.
The purpose of this study was to investigate the relationship between the awareness of gender equality and practice of housing education contents in Technology Home Economics Subject of university students.

Performance of digital video watermarking is an assessment that hides a lot of information in digital videos. Therefore, it is required to find a way that enables to store lots of bits of data into a high quality video of the frequency area of digital contents. Hence, this paper designs a watermarking system improving security with an enhancing watermarking based on invisible watermarking and embedding an watermarking on LH and HL subband and its subband by transforming wavelet after the extraction of luminance component from the frames of video by compromising robustness and invisible of watermarking elements. The performance analysis of security of watermarking is carried out with a statistic method, and makes an assessment of robustness against variety of attacks to invisible watermarking. We can verify the security of watermarking against variety of attacks by testing robustness and invisible through carrying out general signal processing like noise addition, lossy compression, and Low-Pass filtering.

Purpose: The primary objective of this case study is to establish a COQ(Cost of Quality) management system for power generation industries. Key topics of this study include collecting COQ elements, their classifications, COQ computation formula, and determining COQ improvement projects. Results: A comprehensive set of COQ elements have been isolated for electric power generation companies. The COQ elements were classified in such a way that they could be managed according to the PAF model as well as the SIPOC diagram. This study showed that a systematic approach could be established for monitoring the COQ elements and using them in the process of improving quality competitiveness. Methods: The PAF(Prevention-Appraisal-Failure) model has been employed in the process of collecting COQ elements for a power generation company. All the cost of quality elements were first examined through an extensive review of articles and books in the field of quality. The cost elements were then refined and augmented by conducting a comparative study with international standards. The COQ elements have been verified by a group of quality managers and classified according to both the PAF model and the SIPOC diagram for better understanding in the entire organization. An improvement strategy has been also proposed by using a typical COQ level of power generation companies. Conclusion: The conventional PAF model was used in establishing a COQ management system for power generation industries. This case study illustrates the procedure about identification, classification and computation of quality costs, including selection of improvement projects. The system can be used not only for observing the current state of cost elements related to quality, but also for planning an improvement strategy using the ratio of cost classification.

No one doubts that textile and apparel industries have contributed to economic miracles of the export-led growth in Korea. However, by the turning of 1990′s, these sectors have encountered many problems such as decreasing of domestic production and exports mainly due to wage rise and shortage. Therefore, foreign direct investment to the low labor cost countries has been enlarged for a way of improving its competitiveness and increasing exports. However, no intensive study has been made exploring current investments and future directions. This study focuses Vietnam as one of the promising overseas investment countries. The purposes of this study are to analyze current investment status of Korean textiles and apparel firms in Vietnam, to explore merits and problems Vietnam has, and to present useful implications and strategies for Korean textiles and apparel companies. Analysis of current secondary data suggests that Korean apparel industry, rather than textiles industry, have invested more in Vietnam, mostly in southern Ho Chi Minh City. Investments of Korean apparel and textile firms have shown steady increase from 1990 but have turned to a decrease from 1995. Findings suggested that Vietnam has merits for attracting foreign investment since it provides relatively cheap labor and outstanding skillful hands suitable for apparel and textiles industries. In addition, because of EU quota increase and the trade agreement between Vietnam and USA it is likely for firms in Vietnam to increase exports to EU and USA Rapid expansion of domestic apparel market and "Korean trend (Han Rue)" in Vietnam resulted from successful star marketing of Korean firms are another merits Vietnam has to the Korean fm. However, regulations of central government, low efficiency of bureaucratic and stiff administrative process, difficulty of making decision in case of joint venture, lack of social overhead capital, high factory construction costs, weak construction condition, and the excessive competition among investment enterprises have found to be problems. Based on pros and cons of investment to Vietnam, marketing strategies, practical implications and future directions were suggested.
I. Subject of the Study A study on the nutritive composition and utilization of wheat or barley for the improvement in our national dietary life. II. Purpose and Importance of the Stu요 1. Korea has long depended on rice for its staple food, but a sharp increase in population in recent years has brought about the shortage of rice, which makes it inevitable to import a great quantity of foreign rice. It is considered therefore that the development and utilization of other cereals than rice is a serious and pressing problem facing Korea. 2. Wheat and barley are the second largest products next to rice in Korea and it is desired that the composition of several kinds of wheat and barley be analysed and their nutrition which rates with differing degrees of hulling process be specified. 3. In this study, the experiment has been carried out in the following order: first, seven species were selected among various kinds of wheat and barley produced in Korea to analyze their respective composition, and to determine the most ideal degree of hulling process on 5 kinds among the 7 kinds: second, ratio of mixing rice with wheat or barley is increase the nutrition value and to seek selfsufficiency in staple food supply: third, economical and reasonable way of improving the nutrition value in the national dietary life is suggested by developing a simple and easy recipe which is also to the taste of the population.
