Purpose: To compare the efficacy, predictability, stability and safety of excimer laser photorefracive keratectomy(PRK) for myopia and photoastigmatic refractive keratectomy(PARK) for compound myopic astigmatism. Methods: Two-hundred and three eyes(l18 eyes < -7D spherical equivalent, 85 eyes ${\geq}$ -7D spherical equivalent) received excimer laser correction for compound myopic astigmatism and 152 eyes(116 eyes < -7D, 36 eyes ${\geq}$ -7D) for simple myopia. A VISX 20/20B $VisionKey^{TM}$ excimer laser was used to perform either PARK or PRK. Visual acuity with and without correction, refraction, IOP, corneal haze, and topography were evaluated at 1, 3, 6, and 12 months postoperatively. All patients were followed up for more than 12 months. Results: Postoperative refraction were generally stable after 3 months without significant early overcorrection. At 12 months, 110(94.8%) eyes that underwent PRK and 104(88.1%) eyes that underwent PARK achieved UCVA of 20/30 or better in the group who had lower than -7D correction. For eyes treated with -7D or more, these figures were 31(86.1%) eyes after PRK and 57(67.1%) eyes after PARK. The incidences of within 1D of plano refraction at 1 year follow-up were 97.4% after PRK and 93.2% after PARK in the group who had lower than -7D correction. For eyes treated with -7D or more, these figures were 80.6% after PRK and 70.6% after PARK. Conclusions Myopia with or without astigmatism was successfully treated in most of the eyes using PRK or PARK with VISX 20/20B $VisionKey^{TM}$ excimer laser. The predictability and stability of the postoperative refraction during the first 12 months seem to be quite reliable. Further improvement of excimer laser system and software should increase the clinical outcomes and safety of refractive procedures.

학교 현장에서 아이들을 지도하다 보면 문제해결력이 상당히 낮다는 것을 자주 경험하곤 한다. 따라서 그러한 문제점에 대하여 고민하고 다양한 방법을 생각해 보는데, 그 해결 방안으로 소집단 협력학습을 실시하여 아이들의 전반적인 문제해결능력을 높여 보고자 본 연구를 실시하게 되었다. 그러기 위하여 소집단의 구성을 수학 성적을 토대로 하여 5단계로 분류하여 실시하였다. 이에 따른 연구 문제로는 크게 3가지로 정하였는데 다음과 같다. 첫째, 소집단 협력학습이 일제 학습에 비하여 수학 문제해결 능력을 향상시켰는가? (실험반과 비교함) 둘째, 소집단 협력학습이 개인별 수학 문제해결능력을 향상시켰는가? (개인별 비교; 실험반에 국한됨) 셋째, 소집단 협력학습이 수학 교과에 대한 아동들의 수학적인 태도변화를 가져왔는가? 위에서 제시한 연구 문제들을 해결한 결과, 실험반이 비교반보다 문제해결력이 유의미한 수준으로 높게나왔고, 또한 5단계로 분류한 아동들 개개인의 문제해결력에서는 특히 중하위권에 있는 아동들이 실험 후에 문제해결력이 높게 나왔다. 끝으로, 아동들의 수학적인 태도 변화에 관한 설문에서는 소집단 협력학습으로 인하여 수학에 대한 흥미와 자신감이 많이 생긴 것으로 나왔다. 따라서 7차 교육과정에서 주장하는 단계형 수준별 교육과정을 실행하는데 있어서 소집단 협력학습이 하나의 대안이 될 수 있을거라 생각하고, 아동들의 문제해결력을 높이는 또 하나의 수업 형태로서도 시도해 볼만한 것이라 생각한다.

This study proposed a system that can improve the employment rate and maintenance employment rate by filtering information related to employment in analyzing big data for students who want to find employment. The subject was a two-year female university, the existing employment strategy participated in the job search with simple information such as school grades and personality. As a result, the maintenance employment rate was relatively low due to the decrease in the satisfaction of students seeking employment and the incompatibility with the post-employment aptitude. In order to solve these problems, we propose a system that determines and filters whether the input data in the process of analyzing big data such as employment-related information to improve employment and maintenance employment rates.

This study aims to investigate the effects of literary texts as a teaching tool to enhance college students' English communicative competence both in linguistic aspects and affective ones. The control group used only the course book as study material, whereas the target group read four short stories along with it and engaged in a series of follow-up tasks. To measure their English competence, the researcher had both groups take a pre-test and a post-test, compared the results, and analyzed the data using SPSS. The study indicates that though the target students' post-test scores increased, the result failed in reaching a significant level. Nevertheless, reading and discussing literature facilitated the target students' affective aspects of communication. This article points out some other limitations of utilizing literary texts in language teaching and suggests the need for further research to deal with the issues.

However, long-term results of retrospective studies suggest that, for the great majority of individuals, mastectomy or conservative surgery with radiation therapy were be equally effective. The results at 5 and 10 years from prospective randomized trials indicate that survival following primary radiation therapy for early breast cancer is equivalent to that fellowing mastectomy. When competently Performed, Primary radiation therapy gives highly satisfactory cosmetic results and acceptably low rates of local tumor recurrence. A number of controversial issues remain concerning patient evaluation and selection and the optimal techniques of treatment, both surgical and radiotherapeutic. In addition, further work is needed to clearity the best way to integrate primary radiotherapy with adjuvant systemic treatment. And further follow-up of these patients with primary radiation therapy for early beast cancer will be required for ultimate proof of the relative merits. A case which was conservative surgery and radical irradiation of early breast cancer with review of literatures will be done.
