In this study, the method of evaluation of moisturizing ability of cosmetics using specimens was studied as an alternative method of clinical tests. Cosmetic spreadability, surface drying, and moisture loss rate of four specimens (Japanese cake (Maru mochi), Garaetteok, wheat flour, and agar) were evaluated. Also, the water loss rate of the specimens and the transepidermal waterloss were analyzed for 10 kinds of lip make-up products (5 kinds of lipstick, 3 kinds of lip balm, 2 kinds of lip gloss). The moisture loss rate (moisture evaporation sensitivity) of the agar specimen was highest in the order of agar> Garaetteok> Japanese cake> wheat flour. Agar specimens are the most suitable in terms of spreadability, surface crack, and raw material supply. Containers for the preparation of agar specimens are suitable for plastic materials with low heat transfer, which can produce convex, smooth surface specimens. In the evaluation of moisturizing ability of lip makeup products, there was a strong correlation between the water loss rate and the transepidermal waterloss rate measured with agar specimens. These results show that the proposed method can be used as one of the useful alternative test methods.

당뇨병은 혈액 내 포도당 농도가 증가되어, 여러 장기에 합병증을 초래하여 사망률과 이환율을 증가시키고 삶의 질을 저하시키는 만성 대사 질환이다. 당뇨병과 간기능의 효소 수치를 높이는 질환들인 비알코올성 간질환, B형 및 C형 간염, 알코올성 간질환 등은 종종 병존하는 것으로 알려지고 있으나, 원인 및 임상적 의의에 대한 연구는 많지 않다.

The purpose of this study aimed to find the effect of self-esteem and communication competence on clinical practice stress of the Korean nursing students. A total of 198 nursing students participated in this study. Data collection was conducted through the use of questionnaires constructed to include the Rosenberg Self-esteem Scale, Global Interpersonal Communication Competence, and the Clinical Competence Scale. As a result, self-esteem, communication competence, and clinical practice stress of the Korean nursing students were found to be(Self-esteem: $3.4{\pm}0.57$; Communication competence: $3.5{\pm}0.42$; Clinical practice stress: $3.6{\pm}0.58$). Also, the nursing students with female(85.4%), experience of simulation on clinical training(72.2%) were found to have significantly higher clinical practice stress. Moreover, there were significant correlations between self-esteem and undesirable role model(r=.156, p=.029), communication competence and clinical practice stress(r=-.329, p<.001). The factors affecting clinical practice stress were communication competence, gender, satisfaction of clinical practice, and experience of simulation on clinical training. They amounted to 27.8% in clinical practice stress. The results indicate a need to develop effective teaching methods and learning strategies to decrease clinical practice stress of the nursing students.

임상 및 실험 결과를 대외적으로 공인 받기 위해서는 통계적 검정 절차를 거치는 것이 일반적이다. 하지만 통계적 전문 지식이 부족한 사용자가 통계 소프트웨어를 배우는 데는 시간이 많이 걸리며, 결과 해석에도 어려움이 많은 실정이다. 데이터의 특성과 성질에 맞추어 통계법이 선택되어야 하는데, 통계지식이 부족한 초보자들은 가장 일반적인 분석법을 적용시키곤 한다. 이와 같은 방식의 통계분석은 잘못된 결과로 이어질 수 있기 때문에 올바른 분석법을 가이드 해주는 기능이 필요하다. 또한 통계분석법의 적합성을 평가하는데 있어 오차와 잔차의 등분산성 가정이 유용하게 쓰여질 수 있다. 본 연구에서는 사용자에게 올바른 분석법을 제시하는 비쥬얼 가이드 인터페이스와 잔차를 3D Glyph를 이용하여 보여주는 불확실성 시각화 방법을 사용하였다. 분석법 적용에서 나타나는 불확실한 데이터의 시각화는 의사결정에 도움을 줄 수 있다.

This research is to identify the status of the curriculum based on dental hygiene programs, the awareness about medical service technologists, etc. act and job demands of students in the department of dental hygiene. The data was collected by self-reported questionnaires from 536 dental hygiene students. This data was analyzed using SPSS 19.0K program for Windows with a statistical significance level of 0.05. The level of objective awareness of the current Medical Service Technologists Act was higher for females(9.14±1.11) than for males(8.56±1.79)(p=0.043). Meanwhile, there was little difference between college and university(p=0.639), whereas the level dropped as the number of clinical practice experiences went up(p=0.045). Therefore, the law in convergence needs to be revised to reflect the reality of dental hygienists' work, and the dental community needs to change its perception that dental hygienists are not only recognized as assistant workers but also as business partners.

In 1959, Satomura used spectral Doppler ultrasound to express the velocity of red blood cells according to time change, and Kato defined a zero-base line that could tell the direction of blood flow, making it possible to know the direction of blood flow. This became the basis for the widely used classifications of Triphasic, Biphasic, and Monophasic. However, the above classification has limitations that confuse users with the meaning and timing of use in a clinical environment. As a result, the American Society for Vascular Medicine (SVM) and the Society for Vascular Ultrasound (SVU) A consensus document on Doppler waveform analysis was declared by the joint committee. This study tried to review this consensus and to suggest nomenclature and modifiers that can be used in the domestic vascular ultrasound clinical field. The joint committee formed by SVM and SVU recommended that the use of the triphasic waveform and the biphasic waveform be used as a multiphasic waveform rather than being used due to the ambiguity of interpretation. In addition, it was agreed to name the hybrid-type waveform, which is a monophasic and high-resistance waveform, which has always been a problem of interpretation in a clinical environment, as an intermediate resistive waveform. In addition, in order to increase the communication efficiency between the interpreter and the sonographer, waveform analysis was classified into a main descriptor and a modifier, and it was recommended to use a single nomenclature by unifying various synonyms. It is expected that this literature review will provide accurate arterial spectral Doppler waveform interpretation and an agreed-upon nomenclature to radiologists performing vascular ultrasound examination in clinical practice, and will be utilized as basic data that can contribute to the improvement of public health.

Malassezia(Pityrosoprum) pachydermatis에 의한 피부염의 위험요인을 파악하고자 1997년 1월에서 1998년 12월까지 서울대학교 수의과대학 부속동물병원에 내원하여 본 질환으로 진단된 29두와 동일한 기간 동안 피부과 검사에서 임상적으로 건강한 개로 확인된 97 두의 대조군을 대상으로 분석하였다. 각 설명변수에 대한 교차비(odds ratio, OR)와 신뢰구간(confidence interval, CI)은 변수보정법을 사용하여 계산하였다. 다른 공변수를 보정한 상태에서 다중 로지스틱 회귀분석(multiple logistic regression analysis)을 시행한 결과 피부병기왕력(p=0.0059; OR, 4.44; CI, 1.5∼12.8)과 비만(p=0.0013; OR, 5.38; CI, 1.9∼14.9)은 유의한 위험요인으로 나타났다. 단변량 분석(univariate analysis)에서 주 사료로 고기를 섭취하는 경우 피부염의 위험이 높은 변수로 작용하였지만(p=0.0398; OR, 6.38; CI, 1.1∼37.3) 다른 공변수를 보정한 분석에서는 유의하지 않은 것으로 나타났다. 성별, 품종, 및 예방접종은 위험요인으로 작용하지 않았다.

말과 소의 정상 안구내의 구조와 크기를 알아보기 위하여 10마리의 말과 14두의 Holstein 안구를 적출하여 생리식염수내에서 초음파상으로 안구내의 구조를 확인하였으며 각막의 두께, 전방의 깊이, 수정체의 두께, 초자체의 깊이 및 안구축을 측정하였다. 초음파로 측정한 안구를 $-30{\circ}C$ 로 동결한 후 Diamond cutter로 절단하여 caliper로 측정하여 Student-t test로 처리하여 수치를 비교하였다. 초음파상에서 말은 암컷$(35.99{\pm}1.97)과 숫컷(35.94{\pm} 3.36)$, 좌측(36.26)과 우측$(35.67{\pm}2.65)$눈의 크기가 비슷하였으나, 소에서도 좌측$(29.06{\pm} 3.36)과 우측(28.53{\pm} 3.36)$눈의 크기가 비슷하여 통계학적 유의차는 없었다. 본 연구에서는 7.5MHz 초음파기의 B-Mode 방식을 이용하여 말과 소의 안구의 구조를 확인하고 측정하였는데 임상적으로 매우 유용하여 수의안과학에서 적용할수 있는 가치있는 진단법이다.

Evidence based physical therapy interventions for this patient was applied in 15 clinical sessions. Considering the patient's two main impairments, two physical therapy interventions were delivered with WOMAC index outcome measurement. From this case report, I observed that a combined physical therapy interventions consisting of manual therapy, therapeutic exercise, and TENS Unit in patients with knee osteoarthritis may result in decreased pain, stiffness and increased physical function.
