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.

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.

To avoid vessel injury during minimally invasive surgery of the lung, exact knowledge of the pulmonary vasculature is important to surgeon. In this report, we present the case of unusual anatomical variant of the left posterior basal segmental pulmonary artery, arising from the left main pulmonary artery. This anomaly is rare but easily overlooked during interpretation of CT scans, potentially resulting in serious vessel injury during minimally invasive surgery.

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. .

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.
