Background: Cases of simultaneous multiple skin cancers in a single patient have become more common. Due to the multiplicity of lesions, reconstruction in such cases is more difficult than after a single lesion is removed. This study presents a series of patients with multiple facial skin cancers, with an analysis of the surgical removal, reconstruction process, and the results observed during follow-up. Methods: We reviewed 12 patients diagnosed with multiple skin cancers on the face between November 2004 and March 2016. The patients' medical records were retrospectively reviewed to identify the type of skin cancer, the site of onset, methods of surgical removal and reconstruction, complications, and recurrence during follow-up. Results: Nine patients had a single type of cancer occurring as multiple lesions, while three patients had different skin cancer types that occurred together. A total of 30 cancer sites were observed in the 12 patients. The most common cancer site was the nose. Thirteen defects were reconstructed with a flap, while 18 were reconstructed with skin grafting. The only complication was one case of recurrence of basal cell carcinoma. Conclusion: Multiple skin cancers are removed by performing Mohs micrographic surgery or wide excision, resulting in multiple defect sites. The authors emphasize the importance of thoroughly evaluating local lesions surrounding the initially-identified lesions or on other sites when reconstructing a large defect which can not be covered by primary closure. Furthermore, satisfactory results can be obtained by using various methods simultaneously regarding the condition of individual patients, the defect site and size, and the surgeon's preference.

In For the past few years, query log data has been collected to find user's behavior in using the site. Many researches have studied on the usage of query logs to extract user's preference, recommend personalization, improve caching and pre-fetching of Web objects, build better adaptive user interfaces, and also to improve Web search for a search engine application. A query log contain data such as the client's IP address, time and date of request, the resources or page requested, status of request HTTP method used and the type of browser and operating system. A query log can offer valuable insight into web site usage. A proper compilation and interpretation of query log can provide a baseline of statistics that indicate the usage levels of website and can be used as tool to assist decision making in management activities. In this paper we want to discuss on the tasks performed of query logs in pre-processing of web usage mining. We will use query logs from an online newspaper company. The query logs will undergo pre-processing stage, in which the clickstream data is cleaned and partitioned into a set of user interactions which will represent the activities of each user during their visits to the site. The query logs will undergo essential task in pre-processing which are data cleaning and user identification.

This study was carried out to investigate the utilization status of internet and dietary information by gender (boys : 442, girls : 461) in school children (total 903). The results were summarized as follows. The most of children used internet regularly (98.1%) and major purpose of using were mentioned as 'game (39.0%)' and 'social intercourse (49.5%)'. The duration of internet use was '< 2hours (80.9%)' They used internet mainly at 'home (88.8%)', and favorite search engines were 'Yahoo (54.2%)' and 'Daum (31.1%)'. The searching experience on dietary information was from only 35.6% of subjects mainly 'for homework (39.6%)' and 'for health (36.9%)'. The satisfaction degree of searched information was 'high (79.5%)'. Dissatisfactory reasons of internet site for dietary information were pointed out to be 'bring little interest (28.9)', 'difficult contents (19.2%)', and 'poor Information (18.2%)'. Only fifteen % of subjects had experience of nutrition counseling using internet, and purpose of counseling was mainly 'for homework (51.4%)' and 'for health problem (24.3%)'. The problems for nutritional counseling site were pointed out to be 'difficult answer content (31.7%)', 'insincere answer (28.6%)'and 'poor answer content (25.4%)'. They acquire information of nutrition and health management mainly through 'internet (43.7%)'. 'Growth and nutrition (28.3%)', 'improvement in studying ability (13.8%)', 'right weight control (13.3%)' and 'cooking (12.8%)'were most frequently asked information, They had a preference for 'game (40.5%)', 'animation (29.9%)' and 'quiz (18.1%)'as loaming method tools. The favorite site color was 'green (51.3%)'The results of this study showed that although the internet use was very high, they used internet to search dietary information very seldom. Therefore, the information donor should find out what is the optimal tool, what kind of dietary information was needed for school children.

본 연구는 식생경관의 생태학적 해석을 통한 질적 경관평가방법의 모색을 위해 설악산국립공원을 대상으로 생태계 형성위계에 따른 우수 경관자원을 추출한 후 추출된 자원의 시각적 노출량과 탐방객의 탐방로 선호도와의 관계성을 분석하였다. 설악산국립공원을 대상으로 생태학적 해석을 통해 선정한 우수경관 요소로는 아고산식생대와 고지대 바위군, 계곡 낙엽활엽수림, 암반지역 소나무 토지극상, 대경목군락지, 화목류 및 단풍류 우점군락지, 아고산대 침엽수 군락지이다. 연구 결과 탐방로 선호도와 상관성이 있는 우수 경관자원으로는 대경목군락지의 면적, 화목류 우점군락의 면적, 아고산 침엽수군락의 면적이 탐방로의 선호도에 긍정적 영향을 주는 것으로 나타났다. 본 연구에서는 탐방로의 가시권과 우수 경관자원의 분석을 통해 자연지역에서의 일반적 탐방로의 소개에서 나아가 경관자원의 가시성을 바탕으로 특정 탐방로의 특정 탐방시기를 제시할 수 있음을 확인하였다. 일부 경관자원의 가시성이 탐방로 선호에 긍정적 역할을 하고 있었는데 자연환경에서 복잡한 경관요소의 종합적인 가시권 면적보다는 특정 경관의 가시권 면적이 탐방로 선호도에 영향을 주며 단순히 자연지역의 넓은 면적이 시야에 들어오는 지역을 선호하지는 않는 것으로 나타났다.

Castleman`s disease, giant lymph node hyperplasia, is a rare benign disease. The lesion usually consists of a single node, unassociated with any abnormality of the adjacent lymph nodes or other organs. In the first accounts of giant lymph node hyperplasia of Castleman, the lesion was described as solitary and localized to the mediastinum, which is still the most frequent site of involvement. The disease occurs in all age groups and there is no particular sex preference. It is symptomless and is usually detected on chest films as an incidental finding. On a single involvement, it does not recur after excision, whether total or partial, and the main indication of operation is to rule out more serious tumors. Recently multicentric form appears to be a variant of classic giant lymph node hyperplasia and is associated with significant morbidity and mortality. Histologically, two distinct types have been reported; hyaline-vascular and plasma cell. The hyaline-vascular type of lesion is much more common than the plasma cell type. We report two cases of the hyaline-vascular type of Castleman`s disease.

Molipteryx fuliginosa (Uhler, 1860) is a plant juice sucker which feeds on new tips of Rubus oldhami Miquel and Zelkowa serrata Makino, and it has a strong preference for teses two plants in Korea. M. fuliginosa has one generation a year and hibernates as a young adult. Most of the winter survivors emerge in early May. It is the first time their host plants were found and reported. Females mainly lay their eggs one by one separately on the leaves of R. oldhami, and even on the steel wire, the lid guaze and the ground in the laboratory. Nymphs do not gather, but stay on the hatching site, Nymphs except the non-feeding first instar feed on young shoots. From the second to the fifth instar nymphs migrate to the upper part of the shoot and congregate in part on an expanded leaf. The new adults first appeared on 11 August, and remained in the host plant, and fed on until mid October. The duration of the hatching and molting, and the survivorship curve based on the laboratory rearing were determined.
