Purpose: Pediatricians have a significant responsibility to educate mothers about the importance of breastfeeding. However, there have been minimal efforts in the courses of resident training in Korea. The purpose of this study is to evaluate the change in knowledge and attitude before and after a 4-week breastfeeding educational intervention among multicenter residents. Methods: Prospective interventional educational research was designed for residents at eight training hospitals in Korea. Institutional reviews were obtained in each hospital. The education curriculum consisted of 14 courses regarding breastfeeding theory and practice. These materials were used to teach pediatric residents for 4 weeks. Knowledge-based tests were administered before the course, and re-tests were administered after the course using different test items of similar levels. Test scores and survey responses were compared before and after the intervention. Results: A total of 73 residents (1st year 20, 2nd year 23, 3rd year 16, and 4th year residents 14) from eight training hospitals completed the intervention. Their average age was 30.3±2.9 years, 17 (23.3%) were male, 22 (30.1%) were married, and eight had more than one child of their own. The mean pre-test score was 61.8±13.4 and the mean post-test score was 78.3±7.5 (P<0.001). The inter-grade difference in the score was significant in the pre-test (P=0.005), but not significant in the post-test (P=0.155). There were more responses of obtaining confidence after the intervention (P<0.001). Conclusion: In our study, pediatric residents showed improvement in their knowledge and confidence level after 4 weeks of the breastfeeding curriculum. This will provide a basis for future policymaking in the training of pediatric residents regarding breastfeedReceived: 6 January 2022 Revised: 15 February 2022 Accepted: 15 February 2022 Correspondence to: Ellen Ai-Rhan Kim, MD Department of Pediatrics, Asan Medical Center, University of Ulsan College of Medicine, 88 Olympic-ro 43-gil, Songpa-gu, Seoul 05505, Korea Tel: +82-2-3010-3390 Fax: +82-2-3010-6978 E-mail: arkim@amc.seoul.kr A Multi-Center Educational Research Regarding Breastfeeding for Pediatrics Residents in Korea Yong-Sung Choi, MD,PhD1, Sung-Hoon Chung, MD, PhD2, Eun Sun Kim, MD, PhD3, Eun Hee Lee, MD4, Euiseok Jung, MD5, So Yeon Lee, MD, PhD5, Wooryoung Lee, MD6, Hye Sun Yoon, MD, PhD7, Yong Joo Kim, MD, PhD8, Ji Kyoung Park, MD, PhD9, Son Moon Shin, MD, PhD9, and Ellen Ai-Rhan Kim, MD, PhD5 1Department of Pediatrics, Kyung Hee University Hospital, Seoul, Korea 2Department of Pediatrics, Kyung Hee University Hospital at Gangdong, Seoul, Korea 3Department of Pediatrics, Kangwon National University Hospital, Chuncheon, Korea 4Department of Pediatrics, Korea University Anam Hospital, Seoul, Korea 5Department of Pediatrics, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea 6Department of Pediatrics, Soonchunhyang University Seoul Hospital, Seoul, Korea 7Department of Pediatrics, Nowon Eulji Medical Center, Eulji University, Seoul, Korea 8Department of Pediatrics, Hanyang University Seoul Hospital, Seoul, Korea 9Department of Pediatrics, Inje University Busan Paik Hospital, Busan, Korea Neonatal Med 2022 February;29(1):28-35 https://doi.org/10.5385/nm.2022.29.1.28 pISSN 2287-9412 . eISSN 2287-9803 Copyright(c) 2022 By Korean Society of Neonatology This is an Open-Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http:// creativecommons.org/licenses/by-nc/4.0), which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

This study was aimed to get the course which is caused by Neuropsychiatric symptoms in Sang-Han. Therefore this study is based on 『Euhak-Ipmun. Sang-Han』(『醫學入門.傷寒』) classfied mainly by symptoms. The results were summerized as follows: 1. Neuropsychiatric symptoms in 『Euhak-Ipmun. Sang-Han』(『醫學入門. 傷寒』) are explained as Pal-Gang(八綱), which shows those are settled down to a systematic oriental medical theory. 2. Pal-Bup (八法) used in the cure of symptomatische psychose in 『Euhak-Ipmun. Sang-Han』(『醫學入門. 傷寒』), which is intended to boost the effect of cure, choosing the respondent cure method about various causes. 3. Pal-Gang(八綱) and Pal-Bup(八法) in『Euhak-Ipmun. Sang-Han』(『醫學入門·傷寒』) are improved by Lee-Chun(李 ) who added Jang-gi(張機)'s Sang Han theory and new medical thought in the ages of Geum. Won. 4. Lee-Chun(李 ) believed that Neuropsychiatric symptoms which appeared in Sang Hang is caused by the "Unbalance(不平)". So he wanted to reach harmony of "Jeong(精), QI(氣), Shin(神), Hyul(血)" after improving the status of "Unbalance(『不平』)" toward the status of "Balance(平)".

As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.

This experiment was carried out to study the influence of different sowing time, seedling age (the degree of delayed setting) and seedlingbed materials on the growth and yield components of flue-cured tobacco. The variety applied was N.C. 2326, was sown on March 1,11,21 and 31. Those plants were transplanted on the seeding bed mixed humus with sand at the ratio of humus 9 : sand 1 and humus 3: sand 7, 25 days after sowing. Seedlings were grown for 40, 50, 60 and 70 days (from sowing to setting) on the seed bed and seedling bed, and set on the pots (1/5,000a) in the vinyl house. The results obtained were as forlows . 1.The amount of growth of seedlings increased by late sowing and delayed setting. 2.Until the time before the maximum growth stage after setting, stem heigth was larger in the plots of late sowing and delayed setting. After the middle part of maximum growth stage, the earner the sewing time was, the more remarkable the influence of seedling age on the stem elongation was and the larder the seedling age was, the more remarkable the influence of sowing time on the stem elongation was. 3.Stem diameter was large in the plot to late sowing until the early part of maximum growth stage but after the middle part of maximum growth stage the diameter was large in the plants sown at March 11 and March 21. 4.The number of leaves per plant increased by late sowing and delayed setting shown significant difference after maximum growth stage. 5.Late setting made the stem height high and number of leaves per plant more. The size of largest leaf was small in the plot of early sowing and large in the plot set after May 10. 6.It takes more days to reach a topping time from sowing and setting in the case of early sowing and early setting. 7.In early sowing plots, the leaf area of lugs and cutlers decreased by younger seedling age, and in late sowing plots, that decreased by older seedling age. The leaf area of leaf and tip at different treatments showed similar results, but in the plots sown at March 11 and 21, largest leaf was shown in the plot of 50- day seedlings. The area of green tip decreased by late seeding and delayed setting. As a result of theses the plant type showed sylindrical in the plot of early sowing and younger seedling age, and cone shape in the plot of late sewing and older seedling age. 8.The earlier the sowing time and the younger the seedling age were, the heavier the weight of unit leaf area of lugs and cutters, but there were little influences of different sowing time and seedling age on the weight of unit leaf area of leaf, tip and green tip. The percentage of dry matter showed similar tendency to the results of weight of unit leaf area. 9.Late sowing (March, 31) decreases the weight of a cured leaf. Weight of cured cutter was largest in the plots sowing March 1 and that of leaf tip and green tip was largest in the plots sowing March 11 and March 21. The weight of cured lugs was largest in 40 and 50-day seedlings, and that of tip and green tip was largest in 50-day seedlings. There were little differences of weight of a cutter and leaf among the treatments of different seedling age. 10.In 40- day seedlings, the area and weight of leaves per plant increased by late sowing, and in 70-day seedlings, those increased by early sowing. In 50 and 60-day seedlings, those were highest in the plots sown at March 11 and March 21. Largest weight and area of leaves per plant was shown in the plot set on May 10, and the plots set on April 10, and June 1 showed significantly low weight of loaves per plant. 11.Late sowing and older seedling age increased the leaf thickness of those leaves. Different sowing time and the seedling age did not influence on the leaf area contraction ratio and leaf thickness of leaf, tip and green tip. 12.There were significantly negative correlation between leaf area of lug and cutter and weight per unit leaf area, percentage of dry matter and leaf thickness of the lug and cutters, but no correlation between those characters of leaf, tip and green tip. Weight per unit leaf area correlated positively with percentage of dry matter and specific leaf weight in all stalk position. In the lug and cutter, weight per unit leaf area correlated positively with leaf thickness and negatively with leaf area contraction between weight per unit leaf area and leaf area contraction ratio. There were negative correlation between leaf thickness and leaf area contractions of lugs and cutters, and no correlation between those characters of leaf, tip and green tip. 13.There were not significant effects of seedling bed materials applied in this experiment on the growth after setting and yield components.

Semi-solid forming is relatively new process for forming alloys in the semi-solid condition into near net produce. It relies on the behaviour of semi-solid slurrys in which the solid exists in the form of non-dendritic, spheroidal particles in a liquid matrix. Powder of the Al-20Si-5Fe-2Ni alloy was manufactured by spray forming and powder metallurgy, one of the rapid cooling method, and its microstructure became fine with several ㎛ size through the extrusion process. Spray forming and powder metallurgy are a rapid solidification process in which capable of producing materials consisted of very fine, uniform particles. Spray forming can be described as incorperating the advantages of powder metallurgy without disadvantages of degassing and consolidation. In this paper, the microstructural evolution of the P/M, S/F Al-20Si-5Fe-2Ni alloys and wrought Al 2024 alloys were investigated various heating conditions by high frequency induction heating system.

Although there have been many clinical studies about the facial trauma in the recent as well as in the past, severity and frequency of facial trauma are reported multifarious. It seemed to be because of variety of social, cultural, and environmental factors, and the view point of investigators. In this study, we investigated about the patients visiting emergency room during recent 4 years(2004-2007), and compared with retrospective study during former 10 years(1992-1996, 1999-2003) in Dept. OMS Pusan National University Hospital. We assessed the cause, type, demographic, etc, and analyzed alterations of facial bone fractures during past 3 periods. The results were as follows. The total number of patients was increased. 429 patients treated for maxillofacial fractures between January 1992 and December 1996, 466 patients treated between January 1992 and December 1996 and 764 patients treated between January 2004 and December 2007. The male-to-female ratio were 4.6:1, 3.9:1, and 4.16:1, respectively. Patient in the age groups of 10-19 years and 20-29 years increased in the latter two periods. Assaults and falls are decreased gradually, but slip down s are increased. Traffic accidents are still major cause of facial trauma. The mandibular fractures showed the highest incidence thorought three periods. Symphysis fractures of mandible was increased and condyle fractures of mandible was drecreased in the third period.

This study is to investigate the relationship between generally recognized language anxiety and reading anxiety in foreign language learning. The subjects of this article consisted of 77 lst grade middle school students and 82 2nd grade high school students. The total of 159 participants took part in this study. Two inventories assessed two different anxiety levels: the Foreign Language Classroom Anxiety Scale and Reading Anxiety Scale. For statistical analysis, the analysis of variable and correlation analysis were applied by using the SPSS computer program. The results of from the statistical analysis are as follows. · The relationship between generally recognized language anxiety and reading anxiety scale were highly related to each other(r=736). · A statistical correlation was not found between boys and girls, and between middle school and high school students in language and reading anxiety. · The reading comprehension assessment measures consisted of the translation of sentences and a multiple-choice test. The results indicated that more highly anxious students(those with high scores on reading anxiety inventory) tended to take less academic achievements than did those participants who claimed to experience minimal anxiety. · The listening assessment measures were multiple-choice tests. The results indicated that more highly anxious students(those with high scores on language anxiety inventory) tended to get less grades than did those participants who claimed to experience minimal anxiety. · This paper advocates that language anxiety and reading anxiety can play a significant causal role in creating individual differences in both language reading and listening.
