In order to achieve effective human resource development in LIS fields, it is essential to have strategies to nurture and utilize those human resources, in relation to supply and demand as well a sound legal foundation supporting those strategies. Such strategies and legal foundation can only be developed from a complete knowledge of the current status of human resources in the LIS and related industries. This study, therefore, conducted research on the basic employment status, employment environment, and an overall analysis of related issues, in order to address policy implications on the effectiveness of human resource development in the LIS field. This research included the current status of policy environments that involve social environment, and related institutions and laws, and human resources developments as well as the current requirements of librarians in the field, based on a demand survey of LIS employment. It was found that first, there are three distinguishable factors in LIS employment: a feminization of librarianship, an increase in temporary posts, and a high entering ratio into the library workplace. Second, while there were only little differences in the given tasks between full-time and temporary employees, the differences in salary and welfare were considerably larger. Third, field requirements for librarian education included a mentoring system with field experts, short-term internships, and librarian apprenticeships, while job requirements included internship or apprenticeship, language skills, various license acquisition, and career management. Fourth, librarians with licenses for related organizations held 20% more librarian licenses overall.

Stop-motion animation is highly valued for realistic imagery and its ability to captivate the five senses of the audience. Despite this, practical research in this area is limited to date. The long hours required to produce stop-motion animation and turn these into profits can be attributed for the lack of knowledge in this area. In production research, the matter is made worse as it is difficult to protect the intellectual property made through the collaborated efforts of students and teaching staff through each laborious stage of planning, broadcasting and making 2D models. Meanwhile as the animation industry finds the investigation of new production processes taxing, it has maintained its focus on pre-existing processes such as the use of pipeline. This paper aims to shed light on new production methods that can be used to improve the effectiveness of existing stop-motion production. In addition, by working with Taktoon Enterprises on its T.V series Galaxy Kids the paper will revise real world production methods including the traditional use of hand made models. Thus by investigating the use of graphic technology such as 3D printing the paper will be able to extend current business models. Research conducted in this paper is a necessary part of overcoming various contents production obstacles. Furthermore, it may help publicize issues faced in production leading to the discussion and sharing of new innovations.

This thesis is a study on the diagnostic theory and methods of Macjin(checking of pulse) as described in the Whang Di Nei Qing. There are four methods of Macjin in this text, namely: Dong Macjin(動脈法), Sam Bu Gu Who Macjin(三部九脈診). In Young Gi Gu Macjin(人迎氣口脈診法), Nei Qing's Gi Gu Macjin(內徑의 氣口脈法). Each method developed in it's own way, but they are all closely related and became the basis of today's Macjin. I examined the methods of Macjin in the Whang Di Nei Qing from a perspective of "change". The main questions of this study are: "What brought about the development of the different methods?". "How do the methods differ?", and "how did these methods evoke into today's Macjin?". The method of Macjin generated spontaneously from the observation and treatment of disease. Dong Macjin was the first method developed and became the basis of subsequent forms of Macjin. The accumulation of medical knowledge and the influence of oriental philosophy fueled the evolution of Macjin. Chronologically, Macjin methods developed starting with Dong Macjin and eventually into Sam Bu Gu Who Macjin. In Young Gi Gu Macjin, and Nei Qing's Gi Gu Macjin. The different methods of Macjin vary in how many pulse points are checked, and were established with simplicity and effectiveness in mind. Dong Macjin involves the checking the whole body. Sam Bu Gu Who Macjin involves nine points. In Young Gi Gu Macjin involves four points. and Nei Qing's Gi Gu Macjin involves two. In it's early development, the checking of a patient's pulse was used to diagnose only localized disorders in comparison with symptoms. It evolved with Oh Jang Mad(五臟脈, five main types of pulse) to be able to check internal organs with the introduction of Nei Qing's Gi Gu Macjin. After the division of Chon Kwan Chuck(寸關尺), it evolved further to be able to make a detailed diagnosis by using the result of pules checks. Nowadays, we can make 28 forms of diagnostic indices from these development. In conclusion, Macjin can be used practically and effectively in the diagnosis of disease. In using three methods of Macjin(In Young Gi Gu Macjin, Nei Qing's Gi Gu Macjin, and today's Gi Gu Macjin, which can determine the whole body's Siate of well-being) in conjunction with Dong Macjin(which helps pinpoint the localized disorder), an exact diagnosis can be obtained. I strongly feel that we should acquire objectivity by accommodating Macjin with modern methods of medicine.

Purpose : To propose various types of clinical research which is feasible for botanical new drug (IND) development processes, and suggest essential steps to development of study protocol for IND. Methods : Literature-based discussions and one research group's experience is given regarding domestic act, regulation, and system. Results : In order to get an approval of IND for botanical drug in Korea there are several types of clinical research to conduct. In quality control steps for standardized medicinal herbs, case reports or case series can be conducted, and for good manufacturing practice(GMP) steps, we can conduct case reports, case series, and retrospective cohort studies. In addition, as long as we gathered good laboratory practice(GLP) data we can conduct up to quasi-experimental studies and clinical trials including investigator initiated trials. In order to conduct these studies development of study protocol is essential. First, we obtain historical evidence including target disease and indication, efficacy, safety, and endpoints by reviewing medical classics. Second, we obtain clinically and statistically important data by conducting non-clinical studies, observation studies, and quasi-experimental studies. Third, we generate research hypotheses and purposes and explore methodologies, endpoints, clinical practice guidelines, cost-effectiveness, and commercial potential. Finally, we develop study protocol with aid of biostatistician or expert in contract research organization. Discussions and conclusions : This study have obvious limitations in that most thoughts, suggestions, and proposes are from one research group's experience. Therefore, we hope to see various types of research in this topic and process from other research group as well.

In the medical image application the difference of intensity is widely used for the image segmentation and feature extraction, and a well known method is the threshold technique that determines a threshold value and generates a binary image based on the threshold. A frequently-used threshold technique is the Otsu algorithm that provides efficient processing and effective selection criterion for choosing the threshold value. However, we cannot get good segmentation results by applying the Otsu algorithm to chest X-ray images. It is because there are various organic structures around lung regions such as ribs and blood vessels, causing unclear distribution of intensity levels. To overcome the ambiguity, we propose in this paper an effective algorithm to extract pulmonary regions that utilizes the Otsu algorithm after removing the background of an X-ray image, constructs intensity-level maps, and uses them for segmenting the X-ray image. To verify the effectiveness of our method, we compared it with the existing 1-dimensional and 2-dimensional Otsu algorithms, and also the results by expert's naked eyes. The experimental result showed that our method achieved the more accurate extraction of pulmonary regions compared to the Otsu methods and showed the similar result as the naked eye's one.

The purpose of this study was to contribute the improvement of nursing staff development by implementing of effective and organized orientation program using the measure of effectiveness in the application of preceptor program with the reduction of the time of New entry nurse orientation. The subjects were comprised of 116 new entry nurses(59 new entry nurses were employed at June, 1996 and 57 at May & July, 1997) and 79 preceptors, who were in charge of new entry nurse orientation at 1997. These date were collected from June 18, 1996 to August 29, 1997. The characteristics of questionairs applied in this study were general characteristics(7 questions), knowledge of nursing care(138 questions); attitude toward her profession(40 questions) and the degree of satisfaction for the program(5 questions). The questionnairs were developed by the researchers of Asan Medical Center. The Check-list for basic nursing skill were used for the measurement of nursing skill which was developed by nursing department of AMC. The data were analyzed for the mean, standard deviation, difference of mean, ANOV A & t-test. The results of this study are as follows : 1) The changes in knowledge of nursing care : After three months of training the difference of mean between before and after the orientation was higher than the result of two month period training. However, the result was insignificant(p= .469). 2) Performance in nursing practice : Two month period orientation was more effective than three-month training period, however, the statistical significance can not be reached than 3 month period, which resulted in insignificant difference(p=.150). 3) The change in attitude toward her profession : After three-month of orientation, the difference of mean between before and after the orientation was higher than 2 month period orientation, which resulted in significant difference (p=.000). 4) The degree of satisfaction for the program with the time of new entry nurse orientation : After two-month of orientation, the mean of points was 2.57 where the score is higher than 3 month period with mean of 2.30. It resulted in significant difference(p=.000).

The purpose of this study were to a) investigate operation of human resource in contract foodservice management company (CFMC), b) identify the staffing indices for the establishment an labor productivity for CFMC, and c) develop standardized model of staffing demand as foodservice's scale in CFMC. The data was collected using FS intra-net system from 138 contract-managed foodservice operations in A CFMC and statistical analysis was completed using the SAS/win package (ver. 8.0) for description analysis, ANOVA, Duncan multiple comparison, pearson correlation analysis, and regression analysis. The types of operation were included factory (45%), small scale operation (26%), office (11%), department store (10%), training institute (4%), and hospital (3%). The distribution of foodservice scale was classified by meal served was as follows; 'less than 500 meals (47%)', 'from 500 to 1500 meals (25%)', 'from 1500 to 2500 meals (17%)', and 'more than 2500 meals (12%)'. There was two types of contract method, fee-contract (53%) and profit-and-loss contract (46%) Some variables were significantly high operation indices such as selling price, food cost, monthly sales, net profit and others were significantly low operation indices such as labor, meal time a day in the small foodservice on meal scale (p<.001). The more foodservice was large, the more human resource was disposed on dietitian, cook, cooking employee altogether (p<.001). Foodservice in A CFMC was divided into 2 groups by 500 meals a day, according to comparative analysis of labor productivity as meal scale per working hour, meal scale a day and operation indices as meal per foodservice employee, meal per cooking employee (p<.001). The regression equation model was developed as 'the number of employees=1.82+0.014 ${\times}$ meal served' in the operation of less than 500 meals, 'the number of employees=9.42+0.013 ${\times}$ meal scale a day -0.94 ${\times}$ meal scale per working hour' in the operation over 500 meal scale using labor productivity indices and operation indices. Therefore, CFMC could be enhanced efficiency of human resource arrangement using the standardized model of staffing demand and would be increased effectiveness of profit.

Objective : Total resection without consecutive postoperative whole brain radiation therapy is indicated for patients with a single or two sites of brain metastasis, with close follow-up by serial magnetic resonance imaging (MRI). In this study, we explored the effectiveness, usefulness, and safety of this follow-up regimen. Methods : From January 2006 to December 2015, a total of 109 patients (76 males, 33 females) underwent tumor resection as the first treatment for brain metastases (97 patients with single metastases, 12 with two metastases). The mean age was 59.8 years (range 27-80). The location of the 121 tumors in the 109 patients was supratentorial (n=98) and in the cerebellum (n=23). The origin of the primary cancers was lung (n=45), breast (n=17), gastrointestinal tract (n=18), hepatobiliary system (n=8), kidney (n=7), others (n=11), and unknown origin (n=3). The 121 tumors were totally resected. Follow-up involved regular clinical and MRI assessments. Recurrence-free survival (RFS) and overall survival (OS) after tumor resection were analyzed by Kaplan-Meier methods based on clinical prognostic factors. Results : During the follow-up, MRI scans were done for 85 patients (78%) with 97 tumors. Fifty-six of the 97 tumors showed no recurrence without adjuvant local treatment, representing a numerical tumor recurrence-free rate of 57.7%. Mean and median RFS was 13.6 and 5.3 months, respectively. Kaplan-Meier analysis revealed the cerebellar location of the tumor as the only statistically significant prognostic factor related to RFS (p=0.020). Mean and median OS was 15.2 and 8.1 months, respectively. There were no significant prognostic factors related to OS. The survival rate at one year was 8.2% (9 of 109). Conclusion : With close and regular clinical and image follow-up, initial postoperative observation without prompt postoperative radiation therapy can be applied in patients of brain metastasi(e)s when both the tumor(s) are completely resected.

Objective : Acute basilar artery occlusion (BAO) is associated with severe neurological dysfunction and high mortality rates. The benefits of mechanical thrombectomy in BAO have not been explored in recent clinical trials. Therefore, we analyzed outcomes of stent retriever mechanical thrombectomy for BAO, and compared with anterior circulation occlusions (ACO). Methods : In total, 161 consecutive patients (24 BAO, 137 ACO) who underwent mechanical thrombectomy with the stent retriever between January 2013 and August 2016 enrolled in our study. All patients underwent clinical assessment with the National Institutes of Health Stroke Scale (NIHSS) and modified Rankin scale (mRS). Radiological results were used to evaluate thrombolysis in cerebral infarction (TICI) scores and successful recanalization was defined by TICI 2b or 3. Results : Mean NIHSS scores at 24 hours and 30 days were significantly higher in the BAO group than the ACO group (p=0.021, p=0.001). mRS at 90 days was significantly higher in the BAO group (4.2) compared with the ACO group (3.0) (p=0.003). The BAO group (2.0) performed fewer stent retriever passages than the ACO group (2.7) (p=0.049). There were no significant differences between the two groups in terms of complications, but the BAO patients experienced a higher mortality (16.6%) rate than ACO patients (5.8%) (p=0.001). In subgroup analysis of BAO, patients with short procedure times achieved successful recanalization (p=0.001) and successfully recanalized patients exhibited more favorable mRS at 90 days (p=0.027). Conclusion : In our study, mechanical thrombectomy of BAO patients showed worse clinical outcome and higher mortality rate than ACO patients. However, mechanical thrombectomy with a stent retriever in BAO is an effective treatment, because successfully recanalized patients showed good clinical outcome in BAO patients.

A series of experiments was carried out for selecting insecticides and determining proper spraying time to control pea weevil (Bruchus pisorum Linnaeus) in Jeonnam area. In the field trial two times spray with diazinon, carbaryl, imidacloprid, spinosad, etofenprox, clorpyrifos-methyl showed good control effect and threetimes spray showed the better control effect. The second spray (spraying on 10th of May) took the major role of insecticide effectiveness expression for controlling pea weevil. Further trial for selecting insecticides among organophosphates to control pea weevil in lab was conducted and every organophosphate insecticide tested was very effective to pea weevil even at the concentration of one forth of its recommending concentration.
