This study has formed a clear definition of the elements of inquiry skills : inference, determining relationship, causal explanation, prediction, and created the goals of assessment and the items of assessment. They have been checked the validity and the objectivity and the clarity of the items by six professors of science education. At the same time, the two times of the field trial has been executed. and checked the discriminating power and the difficulty index and the effectiveness of distracters, and modified the items. The test developed in this way was administered to 1060 students of the eighth grade, randomly cluster-sampled from the universe, and standardized. The test is the aptitude test as well as the norm-reference test. and has twenty items. The testing-time is thirty minutes. And the cotent validity is 85%, the objectivity of the answer keys 91.7%, the mean of items difficulty 68.8%, the mean of discriminating power 0.39, the standard deviation 3.31, the reliability(K-R 20) 0.69. Because it is the standardized lest, it can diagnose the well-developed skills and the ill-developed skills of the students, and monitor the development of skills.

Although considerable research has been done on the blood chemistry of domestic animals, little work has been made of the changes associated with age. Moreover, the records about physiology of the goat were not much available in Korea, and a comprehensive survey of the blood chemical values of the Korean native goat has not been made. The authors intended to biometric study on the hardness of bone of race horse and Jeju horse in Korea. The measurement of hardness of bone were performed in 272 race horses (Thoroughbred 91, Anglo-Arab 107, Arab 74) and in 109 Jeju horses by the caliper by Toryba's method. Some interesting facts obtained through this study were as follows: 1. There was not significant difference of bone hardness between male and female. The average of bone hardness by the Toryba's meteod were $23.07{\pm}1.01$ in race horse and $19.44{\pm}1.84$ in Jeju horse. 2. The grade of bone hardness of race horse were higher than those of Jeju horse(P<0.001). 3. The correlation coefficient between age and grade of bone hardness were r= +0.344 in Jeju horse, theme were statistically significant (P<0.01) and the regression equation was Y=0.29x+18.497.

Objective : This study aimed to assess the surgical results of the intradural transpetrosectomy for petrous apex meningiomas (PAMs). In addition, we describe the methods and techniques used to expose and manage superior petrous vein and greater superficial petrosal nerve. Methods : The authors conducted a retrospective study of 16 patients with PAMs operated by the senior author via the intradural transpetrosectomy between February 2012 to May 2017. We reviewed patient data regarding the general characteristics, surgical technique and surgery-related outcomes and adopted a combined follow-up strategy of clinic and telephone contacts to evaluate postoperative complications. Results : Simpson grade I and II resection was performed in 10 out of 16 cases (62.5%), and grade III resection were reported in the remaining six cases (37.5%) with no resultant mortality. The mean Karnofsky Performance Status score was 85.6 preoperatively and improved to 91.9 postoperatively, with a mean follow-up period of 34.4 months (range, 6-66 months). Tumor recurrence was found in two patients and they underwent the second surgical operation. Conclusion : PAMs could be completely resected by the intradural transpetrosectomy with an improved survival rate and postoperative life quality. Superior petrous vein and greater superficial petrosal nerve should be managed properly in avoidance of postoperative complications. Finally, most meningioma inside cavernous sinus or adhered to brainstem could be totally removed without postoperative complications.

This study was conducted to identify the level of cultural empathy, self-esteem, and cultural competence and factors affecting cultural competence of nursing students. Participants were 157 nursing students who were 2nd, 3rd, and 4th grade in one university located at the Chungbuk provinces. Data collected using questionnaires which consisted of general characteristics, cultural empathy, self-esteem, and cultural competence. The mean score for cultural empathy was $3.63{\pm}.34$(scores ranged from 1 to 5), The mean score for self-esteem was $2.91{\pm}.42$(scores ranged from 1 to 4). The mean score for cultural competence was $3.31{\pm}.43$(scores ranged from 1 to 5). There were significant differences between cultural competence and age(t=-2.242, p=.027), grade(F=3.473, p=.033), and fluency of foreign language(F=5.053, p=.007). There were significant correlation between cultural competence and cultural empathy(r=.49, p<.001), and self-esteem(r=.33, p<.001)), and self-esteem and cultural empathy(r=.33, p<.001). Cultural empathy and self-esteem explained 29.4% of cultural competence and major predictor variable for cultural competence was cultural empathy. In this paper, we propose various multicultural education programs in curriculum and extra curriculum that can enhance cultural empathy and self-esteem to improve cultural competence of nursing students. Especially, continuous education of cultural knowledge among cultural competence will be done.

본 연구에서는 아스팔트 바인더의 절대점도, 동점도, 침입도, 연화점, PG 고온등급을 이용하여 샌드아스팔트 흔합물의 고속 직접인장강도(DTS1), 저속 직접인장강도(DTS2), 간접인장강도(ITS), 회복탄성계수(MR), 강성지수(SI)를 추정하기 위한 연구를 수행하였다. 여러 가지 혼합물의 특성 중 DTS2가 가장 상관성이 높게 나타났으며 그 다음이 DTS1, ITS, SI, MR 순인 것으로 나타났다. 바인더 성질 중에는 PG 등급이 DTS2와 가장 높은 상관 관계를 보여 PG 고온등급이 높은 바인더를 사용하면 직접인장강도가 어느 정도 우수한 혼합물을 얻을 수 있음을 알 수 있었다. 하지만 각각의 물리적 성질만으로는 신뢰도가 낮아 종합적으로 여러 물성을 이용하여 상관성을 분석하였다. 그 결과 직접 및 간접인장강도는 결정계수가 0.99 이상인 모델을 얻을 수 있었다. 그리고 MR, SI 값의 추정치 모델도 R2이 0.91 및 0.93 이상이어서 상당한 신뢰성을 가지고 물성으로부터 역학적 특성을 추정할 수 있음을 보여준다.

2013년부터 2017년까지 5년간 우리나라 동해안에서 발생한 너울에 의한 사고 사례를 수집하였다. 사고발생역, 발생계절, 발생해안종류, 피해대상별로 분류하고, 사고 당시의 인근지역 파랑관측자료를 수집하여 사고와 파랑자료와의 상관성을 분석하였다. 또한 국립해양조사원의 연안재해취약성 평가 결과에 기반하여 너울 사고 발생지점의 취약성 등급을 분석하였다. 너울 사고지역은 파랑노출지수의 평균등급이 4.91, 파랑민감도지수는 3.87, 종합평가결과인 파랑영향지수는 4.90으로 높게 나타났다. 이에 대부분 너울 사고가 파랑영향지수 5등급에서 발생한 것에 기인하여 동일 등급으로 평가된 동해안 지역(78.7%)을 대상으로 파랑민감도지수와 연계하여 지역을 분류하고 각 지역의 특성에 맞는 대응방안을 마련하였다.

The objective of this study was to explore perceptions of dental student of patients with special care. Their satisfaction with education, and their professional attitudes and behavioral intentions concerning treating these patients were the issues of this paper. Paper-and-pencil survey data were collected from 289 dental students at the school of dentistry, Seoul National University. Most respondents agreed that it is important to be educated about providing care for patients with special needs at the school. The higher grade students they are, they got the higher degree of understanding about treating these patients and the more satisfaction with the education. However, their intentions to treat these patients in their future professional lives were negatively correlated with degree of students. Based on these findings, it is recommended that school curriculum about treating patients with special care be reconsidered to develop students' comfort level in treating special needs populations.

In upper elementary period school adjustment and the effect of parenting face a new set of dynamics. We assumed that parental supervision, affection, incoherence, over-expectation, over-interruption and logical explanation would have an effect on individual trajectories in the development of school adjustment. Additionally, we hypothesized that this model would be different among boys and girls. In this study we analyzed three waves of data collected from 2,378 children nationwide in South Korea. This data was gathered from the Panel Study of Korean Youth and Adolescents conducted by the National Youth Policy Institute(NYPI). Growth-curve longitudinal analysis was conducted and the results indicate that levels of school adjustment had decreased through the $4^{th}$ to $6^{th}$ grade. Parents' supervision, affection and logical explanation significantly predict children's initial school adjustment as well as their rate of decrease in their levels of school adjustment. Parents' supervision had a positive effect on girls' school adjustment. Parents' over-expectation had negative effect on boys' school adjustment levels. Policy implications and future directions for research were also discussed.
