Since it is important to understand data acquiring characteristics through relationship between spatial types and spatial elements and apply it to spatial plans for smooth communication between designer and user of space, the conclusions gained from analysis of data acquiring characteristics of spatial elements through image evaluation by types of interior space can be summarized as in the followings: First, for the amount of acquired data by types of interior space, it shows that the acquired amount of data is to change by types and data acquiring method (phrase and image) even though the spatial elements are same. Second, for the data acquiring process of spatial types by gender, it shows that there is a big difference in acquiring of data according to the evaluation method by phrase and image. Third, for the amount of acquired data of spatial types by gender, it shows that there is a difference between male and female, which is by "classic ${\rightarrow}$ modern ${\rightarrow}$ natural" in case of male and "classic ${\rightarrow}$ natural ${\rightarrow}$ modern" in case of female. regarding both of phrase and image. Fourth, for the evaluation by gender, it shows that there is a deviation in the value of difference according to the elements by which data acquiring characteristics evaluate space. It is considered that this deviation characteristic is in need of reflection in the process of spatial evaluation. This study analyzed data acquiring characteristics of space user's spatial elements through image evaluation by types of space to understand how data acquiring would be changed of spatial elements according to type and gender. Through this study, it expects to make clear that, when a designer is planning a certain space, if the space can be a space for the user by understanding of which elements should be exposed to users by types to acquire more data.

Game producers provide their products and service to users. But the need and desire of users change in many ways as time goes. But game Co. Ltd is difficult because of the capital and the technical identities for providing characteristic products and service etc. Specially, the FPS game which is popular among users is developed by game Co. Ltd as the maximum reflects desire of users, but is similarly developed in other companies FPS game by similar desire. This cannot accept from desire of a certain prospective customer furthermore, decrease of a loyalty customer and a new customer, and a company is difficult of market activity. Therefore, this research is to find of user's psychological needs by FPS game user after gaming on reusing intention and switching intention factors influencing. As the result, the intention of satisfaction and re-use for FPS game is 84.9%, the conversion intention to special force game is 9.6% and the conversion intention to the game of Sudden attack is 5.5%. It shows that desire of the user for certain games is changing.

The purpose of this study was to know how helmet and armor was reinterpreted in historical play by considering general concept and type of old helmet and armor from the aspect of costume history and comparing the helmet and armor types of TV historical plays, Yeongaesomun and Taewangsasingi, whose historical backgrounds were based on the age of Goguryeo. The helmet and armor type shown in Yeongaesomun was reinterpreted as the one, which is close to historical investigation, by reappearing lamellar armor and jongjangpanju(helmet made of slim, long plate) shown in Goguryeo wall painting. The helmet and armor type shown in Taewangsasingi expresses fantastic helmet and armor by adding fantastic factor regardless of historical investigation. The study result reveals that there are several common characteristic factors between the helmet and armors of two historical plays. First, there was a classification in the display of character and story. The helmet and armor type shown in Yeongaesomun classified color and detail design depending on lamellar armor or character. In Taewangsasingi, the helmet and armor was manufactured depending on character's nature and the chain armors, which are lighter than existing helmet and armors, were usual. Second, they escaped from the historical investigation about traditional helmet and armor. In Yeongaesomun, myeonggwangae(a type of armor), which might be popular, was not expressed and Taewangsasingi is free from an imperative idea of historical investigation by manufacturing helmet and armor referring to that of ancient Rome age. The modern sense was reflected to increase dramatic effect. The helmet and armor of Yeongaesomun provides modern feeling by using stainless steel material and modern color arrangement and that of Taewangsasingi is designed in modern, splendid way as it aimed at game development from the planning step.

The purposes of this study are to look into the formative characteristics of the bolero and to evaluate the visual effects and images according to changes in the line and length of the connecting lines of the neck, center front, and hem lines from analyzing the bolero style shown in 2005 S/S domestic fashion. Theoretical examination of the bolero was made philologically with reference books, theses and some articles. And the bolero style shown in 2005 S/S domestic fashion was analyzed with pictures from a fashion magazine "Ceci" and a fashion website 'Interfashion Planning" from Feb. to Aug. of 2005. As a result, the basic lines of the bolero are classified into three different categories according to the connecting lines of the neck, center front line, and hem line. We altered the length of the bolero in three categories with the changes in the waistline-5 cm, 8 cm, and 11 cm. For the visual evaluation, 9 stimuli were placed in mannequins, and were estimated by the experts in the fashion design. For the visual evaluation according to changes in the line and length of the bolero, we used 12 pairs of items to find the visual effects, and 13 pairs of adjectives to measure the visual images. The stimuli and adjectives were randomly given to the evaluators and were evaluated by the 7-Point Likert Type Scale. Data we got from this experiment was analyzed statistically by using the SPSS 12.0 and practiced the Factor Analysis and Correlation Analysis. In the current women's garments, the bolero is a new fashion item which combines with jackets or cardigans. Usually the bolero jacket is made out of a cotton, denim, leather or fur, and the bolero cardigan usually used knitted materials. The design could be very varied depending on the roundness of the center front line, and hem line. According to the result of factor analysis of the visual effects of the Bolero, four factors were identified the whole silhouette, neck line, breasts and shoulders. According to the result of factor analysis of the visual image of the Bolero, three factors were identified maturity, tenderness, neatness.

Objective : The cerebrospinal fluid(CSF) pulsates within the craniospinal axis in response to rhythmic cerebral blood volume variation during the cardiac cycle. The aim of this study is to characterize the normal and abnormal CSF flow and its waveforms in the cervical spinal subarachnoid space. Methods : The magnetic resonance(MR) images were obtained with 1.5 T(GE Signa, GE Medical Systems, Milwaukee, USA) unit using the 2 dimensional cine PC(phase contrast) sequence with cardiac gating and gradient recalled echo imaging. This pulse sequence yielded 16 quantitative flow-encoded images per cardiac cycle. Sagittal and axial images of the cervical spinal CSF space were obtained, and target sites were analyzed for characteristic CSF flow (TR=50ms, TE=12.5-15ms). The region of interest(ROI) was 1mm 3 in volume. Twenty six persons were included in this study : 10 healthy volunteers and 16 patients with cervical myelopathy. The post-operative cine MR study were also done in five patients. Results : The normal CSF pulsation dynamics in the cervical spine showed discrete systolic and diastolic components. The CSF flow revealed a sine wave pattern, in which the systolic phase was shorter than the diastolic phase(ratio=2 : 3). The patient group revealed decreased amplitudes of the CSF flow and irregularly distored flow waves. The systolic phase was elongated in the ROI above the stenotic level, whereas the diastolic phase was lengthened below the level. In the postoperative images, the abnormal pattern and amplitude were found to be corrected. Conclusion : From these results, the authors believe that the CSF flow study provides valuable informations regarding the extent of cervical stenosis and may be useful for the surgical planning and post-operative evaluation.

The nature is the foundation of human life and arts, and human beings have found order and principle amid ceaseless change and harmonization of the nature and diversified patterns and directly or indirectly applied the nature to interior through discovered principles. Interior space to which the organic factors of the nature is an expression of the vitality of the nature and expresses live forms as seen in change, development and growth of living organisms in addition to human feelings. The study aims to recognize the necessity of studies on interior space to which organic expressive characteristics of the nature are applied in uniformed space, suggest expressive characteristics and propose needed basic data required at a time of designing interior space. In this regard, the study has examined works by five contemporary designers including Zaha Hadid, Karim Rashid, Fabio Novembre and Nox with an aim to analyze expressive characteristics of interior design and figure expressive characteristics of organic design found in interior space. According to analyses on preceding literary studies and case studies (14 places), it has been found that organic expressive characteristics in interior space include vision, tactile sensation and auditory sense in terms of sensitivity, immateriality in terms of a property of matter, metaphor and abstraction in terms of the form of natural objects and non-linear curves and free curves in organic design. Organic spaces were characterized by symbolism, directionality, continuity, pattern and superimposition. This conclusion is expected to be useful in subsequent studies on the application of organic expressive characteristic factors at a time of planning interior space in the future.

The rapid climatic changes being caused by global warming are resulting in abnormal weather conditions worldwide, which in some regions have increased the frequency of landslides. This study was aimed to analyze and compare the landslide susceptibility using the Frequency Ratio (FR), Statistical Index, Weight of Evidence, Certainty Factor, and Index of Entropy (IoE) at Woomyeon Mountain in South Korea. Through the construction of a landslide inventory map, 164 landslide locations in total were found, of which 50 (30%) were reserved to validate the model after 114 (70%) had been chosen at random for model training. The sixteen landslide conditioning factors related to topography, hydrology, pedology, and forestry factors were considered. The results were evaluated and compared using relative operating characteristic curve and the statistical indexes. From the analysis, it was shown that the FR and IoE models were better than the other models. The FR model, with a prediction rate of 0.805, performed slightly better than the IoE model with a prediction rate of 0.798. These models had the same sensitivity values of 0.940. The IoE model gave a specific value of 0.329 and an accuracy value of 0.710, which outperforms the FR model which gave 0.276 and 0.680, respectively, to predict the spatial landslide in the study area. The generated landslide susceptibility maps can be useful for disaster and land use planning.

The detection of lymph node metastasis is an important step in tumor staging and is significant for therapy planning. It has been challenged to yield an appropriate image with diagnostic methods such as Magnetic Resonance (MR) and Computed Tomography (CT). Though CT has been used widely and accessed easily to show internal organs, it can hardly provide difference between lymph node and adjacent vessel or fat tissue. It has been well established that MR can reveal the subtle discrepancy within soft tissue. This study investigated the suitability of MR lymph node imaging without contrast enhancement by comparison of T1-weighted image (T1WI) and T2- weighted image (T2WI) in ten normal rabbits. According to the pulse sequence optimized from preliminary study, T1-weighted spin-echo (repetition time/echo time=400/12 ms) and T-2 weighted fast spin-echo (repetition time/echo time=3500/84 ms) images covering the hind limbs and pelvic region were acquired at 1.5 T. Two radiologists scrupulously evaluated the MR images in consensus. And signal intensity of lymph nodes was compared with that of adjacent fat. Statistical analysis showed that T1-weighted coronal image visualized the lymph nodes (iliac, superficial inguinal and popliteal lymph nodes) quickly and consistently rather than T2-weighted one. Conclusively, T1WI for evaluation of lymph nodes is moderately better than T2WI and appears to have potential for quick and sufficient mapping of the lymph nodes. In addition, this normal MR image of lymph nodes could be applied to further study for the evaluation of lymphatic system in abscess and tumor bearing animal model.

PURPOSES : The objective of this study is to identify the characteristics affecting traffic accidents that have occurred in 564 industrial complexes nationwide from 2011 to 2015. METHODS : The traffic accidents were specified using various factors such as industrial complex type (national VS. general), industrial complex degradation (old VS. non-old), location of complex (capital VS. non-capital), and traffic law violation (speeding, signal violation, and median invasion). The average number of crashes and accident ratio (fatal, severe, and both) in terms of characteristics of industrial complexes were calculated. With a sample of crashes of the industrial complexes for 5 years, statistical significances were tested to analyze and compare the differences based on industrial complex and traffic law characteristics using parametric and non-parametric methods. RESULTS : From statistical results, it is observed that the crash frequency occurring in old industrial complexes is three times higher than that in non-old industrial complexes. Old industrial complexes located in a capital area, old national industrial complexes, and old general industrial complexes are considerably related to higher crash frequency, but the fatal accident ratio appeared to have no statistical difference across industrial complex characteristics. Severe crashes are more likely to occur in non-old industrial complexes on an average. CONCLUSIONS : It is necessary to eliminate potential threats to roads and traffic in the same manner as illegal parking in industrial complexes through the restoration of old industrial complexes. To improve the efficiency of road infrastructure, efforts should be made to improve traffic safety in accordance with industrial characteristics such as planning and operation of relevant local government programs.
