Objectives This study aims to investigate current status of the Korean medicine treatment on the cerebral palsy (CP) via interviewing the doctors who have expertise in CP children. Methods From June 2015 to May 2016, the surveys and in-depth interviews were conducted on the fifteen Korean medicine doctors. Results Based on the surveys and interviews, widely-used treatments were body acupuncture and herbal decoction. Scalp acupuncture, intradermal acupuncture and manipulation were also used frequently. Experts stated Korean medicine could be more effective in younger patients, patients with cognitive or language problem. They also stated that Korean medicine has its advantage on strengthening the body to help grow and develop in CP children. However, the absence of guideline related to Korean medicine treatment in CP children as well as high cost are the problems. Finally, the issues regarding Korean medicine treatment in CP children, based on the in-depth interviews, emerged when western medicine is used simultaneously, when having seizure during treatment. Further research is needed for better understanding. Conclusions This study provided current status of the evidence-based Korean medicine treatment in CP children. However, further studies about the addressed issues are needed.

목적 본 연구에서는 초등학생 상담경험 실태조사에서 초등학생의 상담경험과 상담경험 배경변인(상담 장소, 상담자 유형, 상담경험 지각)에 따른 학교적응도와 자기주도학습력의 차이 등을 확인하는 데 목적을 두었다. 방법 일반적인 상담경험 배경에 대한 실태조사 설문과 학교적응(조수정, 2014), 자기주도학습력(이경화, 김수연, 2018) 검사를 초등학생 3~6학년(208명)에게 실시하였고, 수집된 데이터를 사용하여 기술통계, 두 독립표본 t-test, ANOVA 방법으로 SPSS 25.0 프로그램을 통해 통계처리 하였다. 결과 첫째로 초등학생의 상담경험은 학교적응(학업태도와 규칙준수)과 관련이 있었고, 자기주도학습력과의 관련성은 없었다. 둘째로, 상담경험 배경 변인에 따른 학교적응도와 자기주도학습력의 일부 하위요인에서 차이가 있었다. 셋째로 학년에 따른 학교적응도에서의 차이를 나타냈고, 학교적응도와 자기주도학습력 간의 높은 상관을 보였다. 결론 본 연구를 통하여 초등학생의 상담경험과 학교적응, 자기주도학습력 간의 관계를 확인했으며 초등학생의 일반적인 학교 내외의 상담 가운데 특히 학교상담(교사, 학교상담실)은 초등학생의 학교적응과 자기주도학습력에 있어서 중요한 변인임을 알 수 있었다. 이에 본 연구는 초등학생 상담에 대한 학교현장과 관계자에게 일부 시사점을 제공한 것에 의의가 있다. Objectives In this study, the purpose of this study was to identify the difference between school adaptation and self-directed learning ability according to the background variables of counseling experience(counseling location, type of counselor, perception of counseling experience) and counseling experience in the relationship between the counseling experience, school adaptation, and self-directed learning ability of elementary school students. Methods A fact-finding survey on the background of general counseling experience, school adaptability (Jo Soo-jeong, 2014), and self-directed learning ability test (Lee Kyung-hwa, Kim Soo-yeon, 2018) were conducted on 3rd to 6th graders (208 students) of elementary school students. Descriptive statistics, two independent samples t-test, and ANOVA methods were used for SPSS 25.0 program statistical processing. Results First, the counseling experience of elementary school students was related to school adaptation (study attitude and rule observance), but was not related to self-directed learning ability. Second, there were differences in some sub-factors of school adaptation and self-directed learning ability according to the background variable of counseling experience. Third, there was a difference in school adaptation according to grade level, and there was a high correlation between school adaptation and self-directed learning ability. Conclusions Through this study, the relationship between the counseling experience of elementary school students, school adaptation, and self-directed learning ability was confirmed. In addition, it was found that school counseling (teacher, counseling room of school) is an important variable in elementary school students' school adjustment and self-directed learning ability among the general counseling inside and outside school. Therefore, this study is meaningful in that it provided some implications to the school field and related parties regarding counseling for elementary school students.

Predictin of Transmission Error was carried out by using LDP and compared with test results which was measured under no-load condition. Two different type of gear was used in this study, which has same macro-geometry and different micro-geometry. The magnitude of tip relief of gear set A was twice as much as that of gear set B. The Transmission error spectrum of each gear indicated the magnitude of first harmonic of gear set A was twice as much as that of gear set B and LDP Prediction also indicated same results. the comparison of LDP prediction and test results was almost same in 90% accuracy. Design loads of each gear were also found by using LDP and LDP calculated 115Nm for gear set A and 230Nm for gear set B.

This study deals with the TE (Transmission Error) of gear tooth by modifying a profile and lead of a surface of tooth. First, we experimentally confirmed that the TE is a synthesis of the sliding velocity between both gears. Since various types of TE appear in the experiments, we introduced definition of transmission error and the optimism design by modifying a surface parameters. The test stand's performance is then evaluated through a series of multiple torque transmission error tests. Comparisons are made between data recorded before and after the test stand's redesign, and subsequently repeatability studies are performed to verify the veracity of the measured data. Finally, the experimental results are compared to the analytical predictions of two different gear analysis programs.

SCM415 alloy was implanted with nitrogen ions using plasma source ion implantation (PSII), at a dose range of $1{\times}10^{17}\;to\;6{\times}10^{17}N^{+}cm^{-2}$. Auger electron spectrometry (AES) was used to investigate the depth profile of the implanted layer. Friction and wear tests were carried out on a block-on-ring wear tester. Scanning electron microscopy (SEM) was used to observe the micro-morphology of the worn surface. The results revealed that after being implanted with nitrogen ions, the frictional coefficient of the surface layer decreased, and the wear resistance increased with the nitrogen dose. The tribological mechanism was mainly adhesive, and the adhesive wear tended to become weaker oxidative wear with the increase in the nitrogen dose. The effects were mainly attributed to the formation of a hard nitride precipitate and a supersaturated solid solution of nitrogen in the surface layer.

배효제(Hyo-Je Bae),탁성훈(Sung-Hoon Tak),손유선(Yu-Sun Son),하휘파(Heibo He),류성기(Sung-Ki Lyu) 한국기계가공학회 2008 한국기계가공학회 춘추계학술대회 논문집 Vol.2008 No.-

This study deals with the effect of the honing in SCM420H helical gear. Typically, gear honing improves the tooth profile, lead and surface roughness. As a result, gear honing reduces vibration and noise, and will increase the life of gear. And gear honing also changes the surface of gear tooth in a short time and price, so it is a very important method in manufacturing industry. But nowadays, it is hard to find the detail information of gear honing. The test gear is a helical gear that is used in the automotive industry. It is manufactured by the order hobbing, shaving, carburizing and honing. This study investigates the effect of honing in surface shape of SCM420H helical gear, and including fatigue strength test and characteristics of honing of SCM420H helical gear.

Background : Antihypertensive agents such as verapamil and esmolol are well known for their effects of hemodynamic stabilization on tracheal intubation. However, our previous study, Verapamil and esmolol did not attenuate heart rate and blood pressure. The aim of the present study was to evaluate the efficacy of combined administration of these drugs for controlling hemodynamic responses to tracheal intubation. Methods : Forty-eight patients, ASA physical status I or II, were randomly assigned to one of four groups (n = 12 each): normal saline (control), verapamil 0,1 mg/kg, esrnolol 1 mg/kg, and verapamil 0.05 mg/kg mixed with esmolol 0.5 mg/kg, Anesthesia was induced with thiopental 5 mg/kg intra- venously, and then saline, verapamil, esmalol or the mixed drugs were administered as an intravenous bolus, and immediately followed by succinylcholine 1.5 mg/kg. Tracheal intubation was performed 90 s after intravenous injection of experimental drugs. Systolic and diastolic blood pressure and heart rate were measured before induction and every minute for 5 minutes after tracheal intubation. Results : There was a significant attenuation in systolic bload pressure after tracheal intubation in the verapamil and mixed groups compared to the control and esmolol groups. Heart rates were signi- ficantly lower in the esmolol and mixed groups than in the verapamil groups after tracheal intubation. Conealusions : Combined administration of Verapamil 0.05 mg/kg with esmolol 0.5 mg/kg attenuated increases in blood pressure and heart rate after tracheal intubation.
