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.

As the device geometry shrinks to the deep submicron region, chemical mechanical polishing(CMP) planarization become a more essential technique of advanced ULSI process. Also, CMP process was required for the global planarization of inter-metal dielectric(IMD), inter-level dielectric(ILD) layers and interconnections with free-defect. Especially, the complete global planarization of IMD, ILD and interconnections can be achieved only with the CMP process. However, as the IMD and ILD layer gets thinner, several problems were found in the CMP process. It does have various problems such as dishing effect, torn oxide defects and nitride residues in oxide. So, it leads to severe circuit failure, which affects yield. In this paper, we studied the characteristics of polishing pad, which can apply STI-CMP process for global planarization of multilevel interconnection structure. Also, we investigated the effects of different sets of polishing pad, such as soft and hard pad. As an experimental result, hard pad showed center-fast type, and soft pad showed edge-fast type. Totally, the defect level has shown little difference, however, the counts of scratch was defected less than 2 on JR111 pad. Through the above result, we can select optimum polishing pad, so we can expect the improvement of throughput and device yield.

Rice cultivation in paddy field affects the global balance of methane (CH₄) as a key greenhouse gas. To evaluate a potential use of by-product gypsum fertilizer (BGF) in reducing CH₄ emission from paddy soil, CH₄ fluxes from a paddy soil applied with BGF different levels (0, 2, 4 and 8 Mg ha<SUP>-1</SUP>) were investigated by closed-chamber method during rice cultivation period. CH₄ flux significantly decreased (p<0.05) with increasing level of BGF application. 8 Mg ha<SUP>-1</SUP> of BGF addition in soil reduced CH₄ flux by 60.6% compared to control. Decreased soil redox potential (Eh) resulted in increasing CH₄ emission through a CO₂ reduction reaction. The concentrations of dissolved calcium (Ca) and sulfate ion (SO₄<SUP>2-</SUP>) in soil pore water were significantly increased as the application rate of BGF increased and showed negatively correlations with CH₄ flux. Decreased CH₄ flux with BGF application implied that SO₄<SUP>2-</SUP> ion led to decreases in electron availability for methanogen and precipitation reaction of Ca ion with inorganic carbon including carbonate and bicarbonate as a source of CH₄ formation under anoxic condition. BGF application also increased rice grain yield by 16% at 8 Mg ha<SUP>-1</SUP> of BGF addition. Therefore, our results suggest that BGF application can be a good soil management practice to reduce CH₄ emission from paddy soil and to increase rice yield.

Purpose : The purpose of this study was to investigate relationships among family support, self-care, and quality of life of patients with arthritis through a survey. That will be basic data to plan nursing intervention for promoting quality of life for patients with arthritis. Method : The convenient sample of this study consisted of 120 patients with arthritis and data were collected using questionnaires during August 2006 from two OPDs of rheumatoid centers in C University hospitals. The study instruments were used to measure Self Care (So, 1992), Family Support (Kang, 1984), and Quality of Life (Ro, 1988). The data were analyzed using ANOVA, Duncan test, and Pearson correlation. Result : The mean scores were 3.56 for family support, 4.16 for self-care, and 3.19 for quality of life. The level of self-care was significantly higher in those men, having an occupation, higher income, and living with family members. The level of family support was significantly higher in those men, having an occupation, living with family members, and having a helper. The level of quality of life was significantly higher for those men, having a higher income, and shorter length of illness. Three relationships were found to be positively correlated: 1) between the levels of family support and self-care (r=.53), 2) between the levels of self-care and quality of life (r=.55), and 3) between the levels of family support and quality of life (r=.54). Conclusion: Therefore, a nursing intervention program needs to be developed to promote family support, and self-care for quality of life for patients with arthritis.

It is very difficult to control the expansion of reed at a wetland ecological park due to their aggressive reproduction capability. Therefore, proper topography and wetland hydrology should be provided before the construction of a wetland ecological park. Appropriate measures should be taken at the initial stages to prevent reed expansion. Field experiments were conducted at the newly constructed wetland ecological park for 15 months to develop methods to control the reproduction and expansion of Phragmites communis. A complete shading method had the best effect on the prevention of reed reoccurrence among other methods. Complete removal of the rhizomes controlled the reed growth to a greater extent than cutting the aboveground shoots. Water-level manipulation was also better than a half-shading method for the prevention of reed reproduction. These results indicated that soil properties and edge effects can influence the reed growth. Cutting only the aboveground shoots facilitates the growth of reed. These results suggest that reed control should be implemented repeatedly and an alteration in the wetland topography and hydrology may be more effective in the long term. Combination of treatments such as water-level management with shading should be considered to control the growth of reed. Adoptive management for created or restored ecosystem might be considered for accomplishment of its original purpose.

In order to provide the basic information for the water quality of urban streams and the quality variation of these streams, the water pollution indicators of Sin stream and Keumho river flowing through Taegu city were measured, and the variations of COD and OC of stream waters and artifical samples were studied under the condition of stagnation. For this experiment, two sampling sites(Sungpook bridge, Mutae bridge) were selected. Sungpook bridge is located most down the Sin stream, Mutae bridge is located on the lower keumho river. Artificial samples were prepared with mixing starch and CaCl?, and the pHs of these samples were adjusted by adding NaOH and HCl. The results were as follows. 1. The DO values of stream waters sampled in June and July were much lower than those of stream waters sampled in March and April. 2. The COD values of all the samples highly exceeded the fifth grade of environmental criterion(10mg/?) 3. EC highly correlated with ALK and Cl anion. 4. The COD values of stream waters sampled in June and July and stagnated under the laboratory temperature distinctly decreased in process of stagnation, and those of stream waters sampled in April and stagnated in the incubator(20℃) also distinctly decreased. But, the COD variations of stream waters sampled in March and April and stgnated under the laboratory temperature didn't show a distinct tendency. 5. The contents of OC in stream waters sampled in March and April and stagnated under the laboratory temperature distinctly decreased in process of stagnation, and those of stream waters sampled in April and stagnated in the incubator(20℃) also distinctly decreased. But, the contents of OC in stream waters stagnated under the incubator temperature, which was higher than the laboratory temperature, more rapidly decreased in process of stagnation.

Ethnocartography is an analytical, interpretative, and collectible tool to examine diverse cultural elements in view of a heuristic approach. It is possible for us to interpret a culrural boundary and an axle of the geographical mobility of different cultures, according to the historical time of a local society. Anthropologists sometimes question the utility of diffusionism and the cartography of cultural facts after functionalism. Increasingly, however, anthropologists, who had tried to escape the confines of functionalism, are concerned with recovering what they can from a historical and geographical documentation. This method of ethnocartography provides an opportunity to know the diverse aspects of cultural characteristics in which a regional societal is structured. It can help interpret and know not only the structured and underlying rule or order of the society, but also propose useful ethnographic data to understand social strategy for changing a given situation, like the distinction of different social class between aristocratic class and lower class. Also, this method can present a semiologic graph about cultural elements in order to interpret socio-cultural fact which are correlative to each other. That is to say, we must reorganize the ethnographic maps through the critical examination about the geographic cartographic, semiologic graph, and other methods for the detailed description and devices. In this case, we must consider the correlations of diverse instances, and reorganize socio-cultural characteristics dependent on local cultural history which was based on existing geographic and ethnohistorical data. On the local level, specialists must work together to collect, classify, and codify ethnographic data, because this work demands the convergence of multi-dimensional perspectives about the differently structured cultural history far a long time. One can't do it by oneself, but can explore various ways of cooperative work alone with universities, national museums, and research institutes. A cartographer must examine the systematization of the qualitative and quantitative method on the cartographical level, because the cartographical method makes us connect the distribution and changing process of cultural elements in a regional society.

Bilateral diaphragmatic paralysis(BDP) is a rare disorder, which can be secondary to spinal cord injury, motor neuron disease, myopathy, noninfectious polyneuropathy, infection, iced saline cardioplegia performed during cardiac surgery, or idiopathic causes. There may be typical presentations such as dyspnea, paradoxical respiratory movement, and hypercapnic respiratory failure. It needs to exclude above secondary causes to consider idiopathic bilateral diaphragmatic paralysis. We report a 51-years-old man who presented with idiopathic bilateral diaphragmatic paralysis combined with acute pancreatitis. We couldn't find out the association of these two clinical conditions. The patient was improved by mechanical ventilation.

The contents of Han Yul Byung(寒熱病) are explained on the basis of the so-called theory "Yin and Yang, the Five Evolutive Phases(음양오행)". The text of the Han Yul Byung(寒熱病) of the Young Chu(靈樞) was written in the Kap Ul Kyung(甲乙經) chapter 5, 7, 8, 10, 11 and 12. Also it was written in the Tae So(太素) volume 10 and 26. Also it was introduced in the Ryu Kyung(類經) volume 20, 21 and 22 by Jang Kae-Pin(張介賓) in the Myung(明) dynasty. Summarizing the contents of the Han Yul Byung in reference to the contents of successive generation note, the contents run as follows: Chapter 1 deals with the symptoms and treatment of diseases which accompany chills and fever(寒熱病). Chapter 2 deals with arthralgia with other joint systems(骨痺) and flaccid paralysis of Iimbs(體惰病). Chapter 3 deals with indications of five points around the Chen You Points(天牖穴). Chapter 4 deals with the treatment of toothache. Chapter 5 deals with the treatment of headache and eye pain. Chapter 6 deals with the acupuncture manipulation according to changes of season. Chapter 7 deals with the serious influence of carbuncle according to the region of body. Chapter 8 deals with the treatment of heat-syndrome. Chapter 9 deals with the side effect of acupuncture. It is too difficult to understand the Han Yul Byung(寒熱病), because it is written in old chinese. Consequence of above reason, the writer of this article has researched to find out the exact meaning of that.
