This study is an instrumental case study based on a theoretical proposition on animal phobia as a single case, Six categories were derived for the purpose of psychological analysis of the father of a female research participant suffering from the earthworm phobia. They are 'a fearful existence', 'problems with the woman who is always by her father's side', 'secret adultery and shock', 'fear of punishment', 'symbol for earthworm and fear displacement', and 'earthworm phobia'. Anxiety about punishment from a fearful father was the cause of the phobia. For the study participant, the earthworm phobia was the displacement of her father's fear of earthworm, and the earthworm phobia was interpreted as a substitute for her father. In other words, earthworm phobia should be understood as an escape and defense process as it replaces the re-emergence of long-repressed fearful feeling toward her father, and its symbolism can be seen as a metaphorical transformation of the pathological family atmosphere.

This paper showed the difference in the optimum conditions by using the ANSYS CFX simulation program with the changes of the main-blade angle and sub-blade angle. Main-blade Shape 4,which had angle $45^{\circ}$ while other Shapes with angle $0^{\circ}$, was increased to 157.2[%] to 263.2[%] in the power and was increased to 110[%] to 250[%] in the power coefficient. Moreover, when the Shape 5 Fin length of main-blade doubled, the power was 70.8[%] when compared with Shape 1 and 27.5[%] with shape 4.If the main-blade geometry equals shape 1 in the case structure, The power of Case1 was increased to 13.3[%] when compared with Case2. Also, the power coefficient was increased to 15.4[%]. When sub-blade angle was $45^{\circ}$, main-blade was better than the Fin type than the Bended type. The power of Case4 was increased to 47[%] when compared with Csae1 and increased to 13.6[%] with Case 3. Also, the power coefficient was 46.7[%] when compared with Case 1 and 15.8[%] with Case 3.

Energy loss at manholes, often exceeding friction loss of pipes under surcharged flow, is considered as one of the major causes of inundation in urban areas. Therefore, it is necessary to analyze head loss at manholes, especially in case of surcharged flow. Hydraulic experiments were conducted with three cases. Case A is to test whether the shapes of the manholes influence head loss coefficients. Case B and C were proposed to further reduce head losses by improving the manhole hydraulic efficiency. In case B, the joining part of the pipe at both shapes of manholes is shifted from central part to side part. The test in case C is to check the average head loss coefficient by installing the side benching in square manhole, based on shifted joining part model. The average head loss coefficient for circular and square manhole on case A was 1.6. This did not show much difference of the head loss coefficients in spite of the discharge variation in this case. However, case B and C show large difference between head loss coefficients due to the strong oscillation of water surface and the horizontal swirl motion. The circular and square manholes in case B reduced the head loss by 30% and 6% than ones in case A, respectively. The average head loss coefficient for circular manhole in case B was 1.1. Case C reduced average loss coefficients of the square manhole in case A from 1.6 to 1.1. Accordingly, the circular manhole in case B and the square manhole in case C showed the effective way to reduce the head loss. These head loss coefficients could be available to apply to the urban sewer system with surcharged flow.

The purpose of this study is to grasp the actual condition for social exclusion for the elderly, to understand the predictive factors of social exclusion. To achieve this objective, the social exclusion for the elderly was examined targeting 4,040 old people in more than 65 years old by using the second data for Korean Longitudinal Study of Ageing(KLoSA) in 2008 by Korea Labor Institute. First, as a result of examining the actual condition for social exclusion for the elderly, the old people were indicated to be 45.4% for economic exclusion, 78.7% for working exclusion, 17.8% for residing exclusion, 43.8% for health exclusion, 33.7% for educational exclusion, and 34.3% for social-activity exclusion. Second, the possibility to be excluded economically was indicated to be bigger in the older age, in a case of not residing in a city and in the more number in household members. The possibility to be excluded from working was indicated to be higher in a case that old person is woman, in the older age, in a case that old person’s religion is christianity, in a case without spouse, in the more residing in a city, in a case that a household type is poor, in a case of dwelling in apartment, in the more number in household members. The possibility to be excluded from residing was indicated to be higher, in a case without spouse, in the more residing in a city, in a case that a household type is poor, in a case that a residing house type is general house, and in the less number in children. The possibility to be excluded from education was indicated to be higher in a case that old person is woman, in the older age, in a case that religion is not Christianity, in a case without spouse, in a case of not residing in a city, in a case that a household type is poor, in a case of the more children alive. The possibility to be excluded from health was indicated to be higher in a case that old person is woman, in the older age and in a case that a household type is poor. The possibility to be excluded from social activity was indicated to be higher in a case that old person is woman, in the older age, in a case that religion is not Christianity, in a case that a household type is poor, in a case of dwelling in apartment. This study has value as a basic research on social exclusion for the elderly.

Carton and corrugated paperboard have excellent convertibility characteristics that could be easily slitted, folded, and inserted to become a certain shape of box or case. This excellent processing characteristics of carton and corrugated paperboard as well as their recyclability will continue to make them possess high portion in packaging markets. However, staple, tape, or adhesive have been used to seal a paperboard packaging box or case. Staples among them have been frequently used in many cases because of their convenience. Staples could enter the inside the box and give wounds to the goods in the box or case. Furthermore additional handling and waste treatment costs in the making and recycling processes would be necessary when staple is used to seal box or case. This study has been carried out to develop non-staple paperboard packaging box & case designs that can be used to make non-staple boxes & cases. It is believed that the non-staple folding paperboard boxes & cases could be more environmental-friendly, beautiful, and economic than staple boxes & cases.

This review aimed to examine and analyze trends of clinical research using case studies on facial spasms in Korean medicine. Seven web databases were searched for case studies on facial spasms using Korean and English search terms. Case studies were selected using the exclusion and inclusion criteria. Overall, 13 case studies were selected, analyzed, and classified according to the publication year and journal, study participants, cause, treatment methods, pattern identification, evaluation methods, improvement, and side effects. Case studies reporting on various treatment methods in Korean medicine, including acupuncture and pharmacopuncture for facial spasms, have been published since 2000. In addition, studies on new treatment methods in Korean medicine for facial spasm have been published. Combination therapy is the most common method used in Korean medicine-based case studies; therefore, future studies on single treatment are necessary. Most of the case studies on Korean medicine reported improved symptoms and patient satisfaction with the Korean medicine treatment method. No side effects were reported, except for facial swelling and bruising, indicating that Korean medicine treatment methods for facial spasm were safe and effective. Therefore, the Korean medicine treatment methods for facial spasm can be actively used in clinical practice and future research.

'Heaundae Woosin Building' fire was the case that a fire breaking out on the $4^{th}$ floor spread out the $38^{th}$ floor which is a top story and the penthouse was destroyed by fire. After this fire, the fire safety for high rise buildings has been on the rise and several new laws and regulations related in the buildings were created. The study is to analyze Heaundae officetel building case using FDS which is one of the CFD programs for fire. The methodology of this study is to analyze the case comparing with fire spread and route from a virtual fire simulation and related articles and a video clip of actual scene fire. This study shows that a fire spreading on top of levels spent approximately 30 minutes and, which is similar to the actual fire case. Also the pattern of spread has similarity with the case. However, even if the actual fire case shows the fire pattern was "V shape", the smoke-view presents the fire dose not spread horizontally as much as the real fire case. The result shows uncertainty of the modeling based on many grids and a limitation of putting interior finish input sources and the direction of the wind might cause the difference. Also, to analyze factors influencing on a vertical fire, another fire modeling is performed by in condition of modeling environment considering concrete interior finish between buildings and no wind. The result presents the fire spread in smoke-view does not spread vertically as much as the actual case.
