A theme park, in general, can be defined as a space that has both 'theme factor' and 'hands-on factor'. But theme parks in Korea are not recognized as having unity even though they provide diverse services, because they lack in a theme factor, which is the essence of a theme park. On the other side of the issue, themes and concepts that a theme park claims to stand for are not consistent, and they fail to provide representative themes as well. For this reason, although a business plan to invite overseas theme parks is pushed ahead, it causes a vicious circle to weaken the competitive edge of domestic theme park industry as well as capital outflow. Consequently, from a theoretical viewpoint, a theme park with no specific theme is in critical situation to be out of the limelight by failing to provide visitors with purposefulness and attract their attention. To overcome the limitations in domestic theme park industry, and to gain profitability and expanded customers lie in heightening their receptiveness through creating unique image of each theme park. With the awareness of the issue, this study aims to propose a theme-centered park which has culture contents in it and to suggest a viable alternative that helps to create hands-on theme parks that reflect customers' receptiveness.

Purpose: Transbronchial brachytherapy used in the two-dimensional treatment planning difficult to identify the location of the tumor in the affected area to determine the process analysis. In this study, we have done a comparative analysis for the patient's treatment planning using a CT simulator. Materials and Methods: The analysis was performed by the patients who visited the hospital to June 2012. The patient carried out CT-image by CT simulator, and we were plan to compare with a two-dimensional and threedimensional treatment planning using a Oncentra Brachy planning system (Nucletron, Netherland). Results: The location of the catheter was confirmed the each time on a treatment planning for fractionated transbronchial brachytherapy. GTV volumes were $3.5cm^3$ and $3.3cm^3$. Also easy to determine the dose distribution of the tumor, the errors of a dose delivery were confirmed dose distribution of the prescibed dose for GTV. In the first treatment was 92% and the second was 88%. Conclusion: In order to compensate for the problem through a two-dimensional treatment planning, it is necessary to be tested process for the accurate identification and analysis of the treatment volume and dose distribution. Quantitatively determine the dose delivery error process that is reflected to the treatment planning is required.

This descriptive study was done to identify factors influencing sexual satisfaction in women who had had a hysterectomy and to compare these with women who had not had a hysterectomy. The purpose was to contribute theoretical understanding on which to base nursing care planning. One group of subjects were 156 women who had had a hysterectomy, between one and 18 months post surgery, living with their spouse, having no complications, and menstruating before surgery. The other group of subjects were 282 healthy women who were living with their husbands and menstruating. The study tool consisted of 108 items including item concerning personal characteristics, characteristics related to the hysterectomy, husband's support, body image, emotions, attitude toward the sexual relationship, knowledge of sexuality, sexual behavior, and sexual satisfaction. Sexual satisfaction was measured by a tool based on Derogatis Sexual Function Inventory. The range of the internal level of the study tool was from. 5208 to .9462. Data collection was done during the period from June 20 to Aug.20, 1989. The same questionnaire was used of data collection for both groups, but a mail survey method was used for the women who had had a hysterectomy, and an interview method was used for the women who had not had a hysterectomy. Data analysis was done using frequency, ratio, mean and S.D. for the characterstics of the subjects and level of sexual satisfaction. t - test or ANOVA was used for the differences between the groups with regard to the general and hysterectomy related characteristics. The relationship between the score for sex life related factors and the level of sexual satisfaction was analyzed using the Pearson Correlation, and the influencing factors on sexual satisfaction were analyzed by stepwise multiple regression. The results of this study were as follows ; 1. Mean age and income level were the only general characteristics for the two groups that were significantly different. The mean age, and income level of the group who had had a hysterectomy were 45years, and 1,150,000 won respectively, and for those who had not had a hysterectomy, 41 years and 999,000 won. 2. There was no statistical difference of the sexual satisfaction score between the two groups. 3. There was differences in the factors influencing sexual satisfaction between the two groups. Factors influencing sexual satisfaction for the group who had had a hysterectomy were husband's support (R＝.5793, P＝.000) and the women's Knowledge of sexuality(R＝.6670, P＝.000) (total variance : 33.56). On the other hand, emotional status(R＝.4294, P＝.000), sexual behavior(R＝.4294, P＝.000), husband's support(R＝.5274, P＝.000) and attitude towards sexual relations (R＝.5412, P＝.000) (total variance : 54.12) were the factors influencing sexual satisfaction in the group who had not had a hysterectomy. Since husband's support and sexuality knowledge were identified as factors influencing sexual satisfaction of women who have had a hysterectomy, it can be concluded that, before a woman who has had a hysterectomy is discharged from hospital, nurses should include strategies in the nursing care plan that will promote husband's support and the women's knowledge of sexuality.

In this study, we evaluate the effect of respiration on the dose distribution in patient target volume (PTV) during intensity-modulated radiation therapy (IMRT) and research methods to reduce this impact. The dose distributions, homogeneity index (HI), coverage index (CVI), and conformity index of the PTV, which is calculated from the dose-volume histogram (DVH), are compared between the maximum intensity projection (MIP) image-based plan and other images at respiration phases of 30%, 60% and 90%. In addition, the reducing effect of complication caused by patient respiration is estimated in the case of a bolus and the expended PTV on the skin. The HI is increased by approximately twice, and the CVI is relatively decreased without the bolus at other respiration phases. With the bolus and expended PTV, the change in the dose distribution of the PTV is relatively small with patient respiration. Therefore, the usage of the bolus and expended PTV can be considered as one of the methods to improve the accuracy of IMRT in the treatment of breast cancer patients with respiratory motion.

The conventional real-time signal control strategy for oversaturated situation generally requires a number of detectors at the intersection in order to identify the queue length at each approach. Also, existing strategy for the spillback has limited effect due to the temporal spillback control which only reduce the green split at the approach. In this study, a signal control system utilizing the imagery information from ITS roadside equipment is developed for operation of oversaturated intersections. The strategy calculates the saturation ratio based on the queue length extracted from ITS RSE, and designs the signal control variables according to the saturation ratio. The signal control strategy is divided into two phases: oversaturated and supersaturated. In oversaturated conditions, timing plan for main approach is optimized by the queue length. In oversaturated conditions where spillback might occur, the signal timing is designed in order to avoid the spillback. To increase field adaptability, the strategy is designed to adjust the split length, all-red-time, and clearance time, and keep the major signal control variables intact. The result of the simulation shows that in oversaturated conditions, the improvement is similar to the real-time signal control system. In case of, oversaturated conditions, however, the effect of the strategy is superior to that of a real-time system.

For patients receiving chemotherapy and radiation therapy treatment progresses as vomiting, nausea, weight of the patient because of a loss of appetite it is reduced. The patient's weight and the distance from the skin and the treatment site is expected to be closer, thereby reducing the change in the skin because of this dose. This study tests using a loose see the difference between the volume change appears as the weight of the patient using the same phantom and the phantom body of the patient. To using the same as the position EBT film is attached to the skin of the treatment site and was adjusted to the thickness of the Bolus. And using a computerized treatment planning only tomotherapy equipment was passed under the conditions according to the thickness of the radiation dose. To baseline for accurate reproduction position using the MVCT was applied to treated with verification. By passing a total of three dose reduced the error, it was a measure of the film by using a dedicated scanner, EBT VIDAR scanner. Got an increase in the skin dose is displayed each time the thickness of the bolus reduced, in a bolus was completely removed with the highest value. If the changes appeared dose was greater weight loss patients to chemotherapy and therefore bolus thickness variation considering the weight loss of the patient when applying the tomotherapy of nasopharynx cancer was found that the increase in skin dose be increased. This large patient before treatment due to weight loss over the image verification is considered to be established should consider how to re-create your mask and treatment plan for fixing it.

This study examined habitat fragmentation that has occurred in Paju and Yeoncheon, the two border municipalities between North and South Korea in Gyeonggi-do (province) during the last 17 years using various landscape metrics. We 1) classified grass and agricultural habitats and forest habitats from two Landsat TM images collected in 1990 and 2007, and 2) compared the percentage of class area, patch density, mean patch area, and mean perimeter area ratio for the two habitat types between the two time points. Both types of habitats has been severely fragmented due to urban development in the last 17 years. The increased patch density and decreased mean habitat area are attributed to the construction of roads and railroads that separate a large habitat to many small pieces. The increased mean perimeter area ratio also indicates that the habitat fragmentation extended areas that are affected by the edge effect and so less suitable for interior species. A habitat conservation plan is urgently needed to minimize habitat fragmentation from developments that are expected to soon occur in the north and south Korean border.

We introduce a current status and future plans of Korea Microlensing Telescope Network (KMTNet) microlensing experiments, which include an observational strategy, pipeline, event-finder, and collaborations with Spitzer. The KMTNet experiments were initiated in 2015. From 2016, KMTNet observes 27 fields including 6 main fields and 21 subfields. In 2017, we have finished the DIA photometry for all 2016 and 2017 data. Thus, it is possible to do a real-time DIA photometry from 2018. The DIA photometric data is used for finding events from the KMTNet event-finder. The KMTNet event-finder has been improved relative to the previous version, which already found 857 events in 4 main fields of 2015. We have applied the improved version to all 2016 data. As a result, we find that 2597 events are found, and out of them, 265 are found in KMTNet-K2C9 overlapping fields. For increasing the detection efficiency of event-finder, we are working on filtering false events out by machine-learning method. In 2018, we plan to measure event detection efficiency of KMTNet by injecting fake events into the pipeline near the image level. Thanks to high-cadence observations, KMTNet found fruitful interesting events including exoplanets and brown dwarfs, which were not found by other groups. Masses of such exoplanets and brown dwarfs are measured from collaborations with Spitzer and other groups. Especially, KMTNet has been closely cooperating with Spitzer from 2015. Thus, KMTNet observes Spitzer fields. As a result, we could measure the microlens parallaxes for many events. Also, the automated KMTNet PySIS pipeline was developed before the 2017 Spitzer season and it played a very important role in selecting the Spitzer target. For the 2018 Spitzer season, we will improve the PySIS pipeline to obtain better photometric results.

Certain complex forces are existing at the other side of a canvas. These are visual arrangements and within the arrangement, even the simple combination of dots and lines create more than visual patterns. No matter what form that visual art has taken, it is performed in a certain space and it is constucted with various visual elements. For effective communication, visual elements must form a stable sturcture by extablishing organic relationship among each other. These requires an understanding of the human visual characteristics and psychonology, because human sight senses the same biological and psychological visual elements differently in its force and weight, according to the position within a given space. Although the structure which controls such force and weight exists within a peice of work, it is a internal plan of the work that actually controls the communication through a man\ulcorner psychological reactions towards the horizontal and virtical structures within it. Moreover it is a visual statement that effectively expresses a theme or a message. This thesis has studied visual structures through the analysis of art pieces regarding of these kind of a visual picture plane, characteristics of a picture plane formed by a structure of force existing on the other side of the picture and the theory of visual balance. In addition, the aim of this study is to help designers who deals with visual image works to understand the visual structures and psychological recognitions and to apply these picture plane compositions at their real work by recognizing the psychological power within the construction elements.
