Punctuation marks do ancillary functions in a sentence. But, for punctuation marks, we can represent various meaning that don't express by letters. Up to now, punctuation marks' function and their classes in Korean are prescribe by the rules of spelling of Hangeul. However, Punctuation marks are use many Punctuation marks in our everyday life. Till now, there are not any restrictions about those. To conclude, many different sorts of punctuation marks do act a main cause that complicates the comprehension of sentences. In this study, I rendered down punctuation marks' functions. And I emphasized to prepare new prescriptions for those.

Electromotive Force Characteristics of Current Transformer According to the Magnetic Properties of Ferromagnetic Core

김영선 한국전기전자재료학회 2015 Transactions on Electrical and Electronic Material Vol.16 No.1

The most common structure of the current transformer (CT) consists of a length of wire wrapped many times arounda silicon steel ring passed over the circuit being measured. Therefore, the primary circuit of CT consists of a singleturn of the conductor, with a secondary circuit of many tens or hundreds of turns. The primary winding may be apermanent part of the current transformer, with a heavy copper bar to carry the current through the magnetic core. However, when the large current flows into a wire, it is difficult to measure its magnitude of current because the core issaturated and the core shows magnetic nonlinear characteristics. Therefore, we proposed a newly designed CT whichhas an air gap in the core to decrease the generated magnetic flux. Adding the air gap in the magnetic path increasesthe total magnetic reluctance against the same magnetic motive force (MMF). Using a ferrite core instead of steelalso causes the generation of low magnetic flux. These features can protect the magnetic saturation of the CT corecompared with the steel core. This technique can help the design of the CT to obtain a special shape and size.

Purpose. The aim of this study was to provide Aromatherapist with analysis of the effect of natural aroma essential oil on middle school students' self-concept. Methods. In total, 20 students were recruited to answer a self-administered questionnaire in pre and post. The questionnaire was composed of questions about general self-concept, class self-concept, achievement self-concept, ability self-concept, social self-concept, family self-concept, emotional self-concept, physical self-concept. The natural aroma essential oil program was operational in a 90-minute once a week for ten weeks. Results. As a result, the score of emotional self-concept(t=-2.60, p<.05) is higher than pre the experiment post experiment. Conclusions. This study is to get a basic data of natural aroma should be applied to improve self-concept of middle school students.

Jarcho-Levin syndrome (JLS) is a rare congenital dysostosis characterized by multiple vertebral and costal anomalies. The combination of JLS and neural tube defect is rare. Only six cases of JLS accompanying diastematomyelia have been reported; all were in infants or children. We present the case of a 37-year-old female patient with JLS who also had diastematomyelia in lumbar vertebral level. This is the seventh case of JLS with diastematomyelia, and the first adult case.

The Validity and Reliability of the Second Korean Working Conditions Survey

김영선,이경용,오민정,박정순 한국산업안전보건공단 산업안전보건연구원 2013 Safety and health at work Vol.4 No.2

Background The aim of this study was to evaluate the quality of the Second Korean Working Conditions Survey (KWCS), focusing on its validity and reliability. Methods The external validity was evaluated by the assessment of sampling procedures and the response rate, in order to investigate the representativeness of the sample. The content validity was evaluated by the assessment of the development of the questionnaire, and the consistency of questions for the selected construct. The test-retest method was used to evaluate the reliability by means of a phone call survey of 30% of the respondents, who were randomly selected. The respondents' satisfaction regarding the survey procedures and interview time were analyzed to evaluate the quality of survey data. Results The external validity was assured by an acceptable sampling procedure, rigid multi-stage stratified cluster random sampling. The content validity was also guaranteed by a reasonable procedure for the development of the questionnaire with a pretest. The internal consistency of the questions for work autonomy was maintained, with 0.738 of Cronbach's alpha. The response rate of 36% was lower than that of the European Working Conditions Survey (EWCS), with a contact rate of 66%, compared to 76% for the EWCS. The matching rates of the five retested questions were more than 98% reliable. Conclusion The quality of the second KWCS was assured by the high external and content validity and reliability. The rigid sampling procedure and development of the questionnaire contributed to quality assurance. The high level of reliability may be guaranteed by the sophisticated field survey procedures and the development of a technical manual for interviewers. The technical strategies for a high response rate should be developed for future surveys.

This study was conducted to evaluate the selective control of creeping bentgrass invaded in Kentucky bluegrass by applying several herbicides and recovery of Kentucky bluegrass by sand injection seeding method. Selective herbicides such as mecoprop, triclopyr-TEA, imazaquin, bentazone and penosulam pyrazosulfuro- ethyl and non-selective herbicides such as glyphosate, paraquat dichloride and glyphsate ammonium oxyflorfen were used. Selective suppression of creeping bentgrass in Kentucky bluegrass was evaluated by turf color, chlorophyll and visual control indexes. Control of creeping bentgrass was most effective with the double dose application of triclopyr-TEA (2 Tri-T) in the selective herbicides and the 1 / 5 dose application of glyphosate ammonium oxyflorfen (1 / 5 GAO) in the non-selective herbicides. Visual control indexes by 2 Tri-T in selective herbicides and 1 / 5 GAOin non-selective herbicides were investigated 6.0 and 7.4, respectively. Treated sites were covered completely in 50 days after seeding Kentucky bluegrass by sand injection method. 본 연구는 켄터키블루그래스 내에 발생한 크리핑벤트그래스를 방제하기 위하여 제초제를 선발하고, 그 피해 지역에 켄터키블루그래스의 샌드인젝션파종에 의한 회복방법을 개발하기 위해 수행되었다. 약제선발시험에 이용된제초제는 메코프로프액제(mecoprop; MCPP), 트리클로로피르티이에이액제(triclopyr-TEA; Tri-T), 이마자퀸액제(imazaquin; Ima), 벤타존액제(bentazone; Ben) 및 페녹슐람 피라조설퓨론에틸입상수화제(penoxsulam pyrazosulfuron-ethyl; PPE)와 같은 선택성제초제와 글리포세이트액제(glyphosate; Gly), 파라콰트디클로라이드액제(paraquatdichloride; Pad) 및 글리포세이트암모늄 옥시플루오르펜입상수화제(glyphosate ammonium oxyflorfen; GAO)와 같은 비선택성제초제를 이용하였다. 엽색지수와 엽록소지수 및 방제 효과를 통해 크리핑벤트그래스의 방제에 효과적인선택성제초제는 Tri-T 배량(2Tri-T)처리이었으며, 비선택성 제초제 중에서는 GAO 1/5량(1/5GAO)이 우수하였다. 크리핑벤트그래스가 침입한 켄터키블루그래스 포장에서 2Tri-T와 1/5GAO의 방제효과는 각각 6.0과 7.4로 우수하였다. 방제지역에 켄터키블루그래스를 샌드인젝션을 통해 파종 후 약 30일 후에는 약 70±3% 정도의 피복율을 보였고, 50일 후에는 대조구와 비슷하게 회복되었다.

BACKGROUND: Nitrogen (N) is an important element for turfgrass (Zoysia matrella) growth; however, standard N application rate for turfgrass is not established yet. This study was conducted to evaluate the effect of N applica-tion rates on the growth and quality of turfgrass for estab-lishment of standard N application rate. METHODS AND RESULTS: Treatments were as fol-lows; control (0 N g/m2/month), 1N (1 N g/m2/month), 2N (2 N g/m2/month), 3N (3 N g/m2/month), 4N (4 N g/m2/ month), and 5N (5 N g/m2/month). N application im-proved visual turfgrass quality. Compared with the con-trol, clipping yield of all N treatments increased by 90~ 194%. The grass shoot weight of 3N, 4N, and 5N treat-ments increased by 52%, 43%, and 111%, respectively, and the stolon weight of 4N and 5N treatments increased by 412% and 201%, respectively, compared to the control. The N uptake amount and N recovery rate were estimated to be 4.10~6.28 g/m2 and 14~58%, respectively. CONCLUSION(S): These results indicate that consider-ing visual quality, clipping yield, N uptake amount, and N recovery, the application rate of 2~3 N g/m2/month was suggested to be suitable for Z. matrella production. .
