Objectives: This study aimed to determine the prevalence of odontogenic cysts, tumors, and other lesions among reports in the archives of the Department of Oral and Maxillofacial Surgery at the Faculty of Dentistry affiliated with Kocaeli University collected over a four-year period. Materials and Methods: In this retrospective study, patient records from the archive of the Department of Oral and Maxillofacial Surgery from 2014 to 2018 were reviewed. Patient demographic information (age and sex) and lesion location were recorded and analyzed. Results: From a total of 475 files reviewed, odontogenic cyst was confirmed in 340 cases (71.6%), and odontogenic tumor was confirmed in 52 cases (10.9%). Regarding odontogenic cyst type, the most common was radicular cyst (216 cases), followed by dentigerous cyst (77 cases) and odontogenic keratocyst (23 cases). Among odontogenic tumors, the most frequent was odontoma (19 cases), followed by ossifying fibroma (18 cases) and ameloblastoma (9 cases). Giant cell granuloma was also reported in 35 cases. Conclusion: The distribution pattern of odontogenic cysts and tumors in our retrospective study is relatively similar to that reported in the literature. Complete clinical reports for final diagnosis of these lesions and routine follow-up examinations are very important for treatment.

Hypertropied palatine tonsil is a common disorder in pediatric otolaryngology. It could be easily observed and adenoid vegetation could induce maxillary sinusitis by the obstruction of nasopharynx and choanae. This is a study on the relationship of the hypertropied palatine tonsil, 42cases, with maxillary sinusitis and adenoid vegetation The results was as followings ; 1. The sex distribution was male 30cases($71.4\%$), female 12cases($28.6\%$) and age distribution was from 3 to 17year-old. 2. Hypertropied palatine tonsil distribution was the degree of both 3, 2cases($4.8\%$), one 3 the other 2, 3cases($7.l\%$), both 2, 22cases($52.4\%$), one 2 the other 1, 9cases($21.4\%$), both 1, 5 cases($11.9\%$). and only one 1, 1case($2.3\%$). 3. By the PNS X-ray, there were resulted 29 cases($69.0\%$) both maxillary sintis, 4cases($9.5\%$) only one maxillary sinusitis and 9cases($21.4\%$) norma] sinus. 4. By the Head latera] X-ray, there were resulted 13cases($31.0\%$) large adenoid, 24cases($57.l\%$) mediate adenoid, and 5cases($l1.9\%$) small adenoid.

Objective: This study aimed to introduce cases of exposure to humidifier disinfectant (HD) in hospitals and to present their exposure characteristics. Methods: We used data from 4,393 subjects who participated in the fourth assessment survey of environmental exposure to HD conducted by the Korea Environmental Industry & Technology Institute. In this study, we selected 301 subjects who reported their place of use of HD as a hospital. Then, we classified cases as 'Hospital-provided'. 'Probably hospital-provided', 'Individual purchased', and 'Unknown' according to the supply sources of HD. Also, we introduced detailed exposure characteristics for the selected cases. Results: Of the 4,393 subjects, 301 (6.9%) reported the use of HD in 392 hospitals (including duplicate answers for the use in ${\geq}2$ hospitals). The 301 hospital-user subjects included 139 survivors and 162 non-survivors. When we classified the 392 cases by supply sources, 'Hospital-provided' was 12.2% (48 cases), 'Probably hospital-provided' was 25.5% (100 cases), 'Individual purchased' was 59.7% (234 cases), and 'Unknown' was 2.6% (10 cases). Among the 'Hospital-provided' cases, we selected six cases and provided a detailed description of the HD use in this study. Additionally, we reported details for six cases that had purchased HD upon a doctor or nurse's recommendation and for three cases that had purchased it at hospital stores. Conclusion: This study presents various cases of HD exposure in hospitals. Because there may be a considerable burden of HD exposure in public spaces, including hospitals, further studies are necessary to assess HD exposure in hospitals and public places.

Objective: The aim of this study is to investigate service design cases by online service companies and suggests framework to understand service design of them. Background: Recently, exploratory service design cases by online service companies such as Google, Apple, and NHN has been developed. Service design and online service experience design has been booming among user experience professionals but these two areas are not clearly defined. It is interesting to study the definition and key factors of service design and online service experience design. Moreover, investigating service design cases by online service companies is needed. Method: Due to diversification of service design cases by online service companies, this study has reviewed online resources and literatures about top 5 online service companies in USA and Korea. Furthermore, this study used expert interview who worked for service design at NHN. To understand the attributes of service design cases, this study developed 3 types of service design classifications scheme such as service design as extension of online service, space design and event service design. Finally, this study suggested a new framework for service design cases. Results: This study investigated service design cases by online service companies and suggests key issues and frameworks to uncover service design for online service. Conclusion: Service design cases for online service was analyzed by $2^*2$ matrix(extension, $enrichment^*product$, service) to explain characteristics and attributes. NHN's Knowledge-iN bookshelf at NHN library1 is a unique form of service design as a tool of enrichment of online experience. Application: The results of this study might help to understand service design cases and plan new service design for online service companies with structured framework.

Mediastinal tumors have long fascinated the thoracic surgeon because of their variety and unpredictability of diagnosis prior to exploration. We report the analysis of the 110 cases of mediastinal tumors, experienced in the dept. of the thoracic and cardiovascular surgery of the National Medical Center from December 1959 to August 1983. The age distribution was relatively even and the mean age was 37 years old. The germ cell tumors were 29 cases [31%], the neurogenic tumors were 19 cases [20%], the thymomas were 16 cases [17%], the lymphomas were 8 cases [8.5%], the primary or secondary carcinomas were 11 cases [12%], the bronchogenic and the P.W cysts were 4 cases, the mesenchymal tumors were 3 cases, the TB gangliomas were 3 cases among the 94 cases, histologically analysed. The malignant tumors were 39 cases [41%]. In classified by histological types, the tumor size, location and the clinical manifestations are presented. The successful removal was done in 53 cases [96%] among 55 cases of benign mediastinal tumors. In 39 malignant cases, the surgical intervention had been done in 21 cases [54%], and inoperable cases were 16 [41%], and the operative deaths were 2 cases [5%].
