This survey was conducted to assess dining-out behaviors and menu preferences of university students in the Seoul area. The results were as follows: 1. 65.2% ate out rarely for breakfast and 73.1% ate out frequently for lunch, whereas 20.9% occasionally ate out for lunch. The frequency of dining out for breakfast was influenced by age, gender, and major but the frequency of dining out for lunch was significantly correlated with age(P < 0.01). 79.2% of females dined out frequently, but 62.3% of males reported doing so(P < 0.001). 65.2% ate out frequently for dinner and 31.6% did so occasionally. 34.2% dined out frequently for snacks, and 53.5% did so occasionally. 2. Factors to consider in dining out were as follows: taste > preference > price > persuasion > nutrition. The motivations for dining out were as follows: convenience > favorite food > difficult to prepare lunch box > difficult to carry lunch box > habit. This factor was correlated significantly with age(P < 0.05) and residence type(P < 0.001). Problems with dining out were listed as follows: unbalanced nutrition > price > sanitation > variety of menu > taste. This factor was correlated significantly with age(P < 0.05), alcoholic beverage use(P < 0.01) and smoking(P < 0.01). 3. Foods selected for meals when dining out were as follows: Korean style > Western > Japanese > noodles > Chinese. The expense(in won) of dining out for lunch was as follows: 3,000${\sim}$5,000 > 2,000${\sim}$3,000 > over 5,000 > under 2000. Problems to be corrected in Korean-style food were as follows: variety of menu > price > using personal dish. 4.

Warpage of injection molded product is caused by non-uniform shrinkage during shaping operation and relaxation of residual stress. Robust part design and glass fiber reinforced reins have been adopted to prevent warpage of part. Warpages for part designs have been investigated in this study according to the injection molding conditions. Part design contains flat specimen and two different rib designs in the flat part. Resins used in this study were glass fiber reinforced amorphous plastics, PC and ABS. Different rib designs showed significant differences of warpages in the parts. Various warpages have been observed in the three regions of the part, near gate region, opposite region to the gate, and flow direction region. Results of computer simulation revealed that the warpages were strongly related to glass fiber orientation. Flat specimen showed the smallest warpage and the specimen with ribs to the flow direction showed a high resistance to warpage. Warpage highly depended upon part design rather than molding condition. It was concluded that the rib design and selection of gate location in injection molding would be the most important factors for the control of warpage since those are directly related to the fiber orientation during molding.

Steel piers and concrete-filled steel(CFS) piers, in spite of reasonable strength, high ductility, small section, and fast construction, have not been considered as one of alternatives to RC piers even in the highly populated urban area where aseismic safety, limited space and fast construction are indispensably required. This paper, the first of two companion papers for the seismic performance of steel and CFS piers, tests steel and CFS piers under quasi-static cyclic loading to estimate their ductility and strength. Additional details such as rebars and base ribs are added to increase the ductility of a concrete-filled steel pier with minimum additional cost. Also, simplified numerical analyses using nonlinear spring and shell elements are examined for the estimation of the ductility and strength of concrete-filled steel piers and a steel pier. The result shows that concrete-filled steel peirs have higher energy absorption, i.e., ductility and strength than those of steel pier and increasing bonding between in-filled concrete and lower diaphragm, and the improved details of stress concentrated region would be important for the ductility and strength of a pier. Numerical results show that simplified modeling with nonlinear springs and shells has potential to be effective modeling technique to estimate the seismic performance of a concrete-filled steel pier.

Objectives : The aim of this study is to report a case of a 51-year-old patient with Herpes zoster, whose symptoms were relieved within five weeks after the East-west medical combined treatment. Methods : A Herpes zoster patient with extreme pain around the right lower ribs and lower back was admitted into the Korean medicine hospital. Bee venom acupuncture was applied directly onto the site of pain and electroacupuncture was applied on $GV_6-BL_{20}$, inferior site of spinous process of the 12th thoracic vertebra-$BL_{21}$, $GV_5-BL_{22}$, $GV_4-BL_{23}$ six times a week. Moxibustion was applied on $BL_{49}$, $BL_{50}$, $BL_{51}$, $BL_{52}$, $GB_{25}$, $LR_{13}$ six times a week, and the patient took daily doses of herbal medicine and western medicines such as anticonvulsants, analgesics, antiepileptics. The patient's symptoms were evaluated with numeric rating scale(NRS) and neuropathic pain scale(NPS). Results : The results were as follows: 1. After the East-west medical combined treatment, the NRS grade decreased from 8 to 1. 2. On the neuropathic pain scale, the patient's symptoms changed from deep sharp pain and burning sensation to superficial dull pain and coldness. Sensitivity to touch, discomfort, and itchiness also decreased. Sudden attacks of pain appeared 14 to 21 days after onset, but disappeared after final treatment. Conclusions : The results of the above patient suggests that the East-west medical combined treatment may be effective for total remission of herpes zoster. Further research is needed to confirm such effects.

Surface roughness is one of implant surface topography and it's found that surface roughness characterizations, such as surface energy, oxide layer thickness and its chemical composition, are closely correlated if the roughness is changed. Several studies showed the importance of analyzing surface structure so the surface structure of thread implant was analyzed to measure the implant quality exactly. In this study, surface roughness of 4 implants - MK $II^{(R)}$(Nobel Biocare), $RBM^{(R)}$(Life-Core, USA), $Osseotite^{(R)}$(3i, USA), $TPS^{(R)}$(Life-Core, USA) - were measured using $Accura^{(R)}$ and 40 implants were installed into 4 sets of ten bovine ribs based on the parameters from the measurements. From this test, the following conclusions for the initial stability were drawn by measuring and comparing RFA, Periotest Value (PTV), Removal Torgue Value (RTV). 1. $R_a$ value in surface roughness measurement was increasing by the order of $MKII^{(R)}$, $Osseotite^{(R)}$, $RBM^{(R)}$, $TPS^{(R)}$ and $R_q$ value was the same order. 2. $R_q$ value in each section was observed to increase by the order of $MKII^{(R)}$, $Osseotite^{(R)}$, $RBM^{(R)}$, $TPS^{(R)}$ in top and $MKII^{(R)}$, $RBM^{(R)}$, $Osseotite^{(R)}$, $TPS^{(R)}$ in mid-section but the value of $MKII^{(R)}$ bottom was the lowest, followed by $Osseotite^{(R)}$, $RBM^{(R)}$ and $TPS^{(R)}$. 3. RFA increased by the order of $RBM^{(R)}$(7042Hz), $MKII^{(R)}$(7047Hz), $Osseotite^{(R)}$(7076Hz), $TPS^{(R)}$(7168Hz) and there was no significance between each group. 4. PTV was increasing by the order of $MKII^{(R)}$(-1.62), $TPS^{(R)}$(-1.92), $Osseotite^{(R)}$ & $RBM^{(R)}$(-2.08) and there was no significance, either. 5. Removal torque in RTV measurement showed the increasing order of $MKII^{(R)}(5.31kgf{\cdot}cm)$, $Oeeotite^{(R)}(5.71kgf{\cdot}cm)$, $TPS^{(R)}(5.92kgf{\cdot}cm)$ and $RBM^{(R)}(7.24kgf{\cdot}cm)$ and there was no significance among groups. Above observations explains that surface roughness does not make any impact on the initial stability of implants installation.

Purpose: Sternocostoclavicular hyperostosis (SCCH) is a disease of unknown etiology, which is characterized by periosteal reaction and endosteal hyperossification of the sternum, clavicles and upper ribs as well as ossification of the surrounding soft tissue. SCCH is a well recognized but uncommon condition which is important differential diagnosis to consider to avoid misdiagnosis and to differentiate the condition from malignant process. But few studies have reported long-term clinical result of SCCH. We report long-term clinical result of SCCH. Materials and Methods: From 1986 to 2000, 17 cases of SCCH were followed up over two to 14 years. We evaluated the radiologic, pathologic and clinical results. Results: Four men and thirteen women were studied. The age when first symptom appeared were raged from17 to 60(average-48.7) There are no specific bacteriological, serological or histological finding. Usually a permanent increase in the erythrocyte sedimentation rate is found. The radiological examination showed the signs of proliferate destructive arthritis in most case. The majority of patients respond to NSAIDs and antibiotics. Conclusion: Sternocostoclavicular hyperostosis is uncommon benign condition, but important condition in the differential diagnosis of inflammatory or malignant process of this joint.

In Korea, hepatoma is the thirdly frequent cause of death from cancer occupying 17.2% among the whole deaths from cancer and the rate of death from hepatoma comes to about 21's persons per one-hundred thousand ones. This paper proposes an automatic method for the extraction of areas being suspicious as hepatoma from a CT scan and evaluates the availability as an auxiliary tool for the diagnosis of hepatoma. For detecting tumors in the internal of the liver from CT scans, first, an area of the liver is extracted from about $45{\sim}50's$ CT scans obtained by scanning in 2.5-mm intervals starting from the lower part of the chest. In the extraction of an area of the liver, after unconcerned areas outside of the ribs being removed, areas of the internal organs are separated and enlarged by using intensity information of the CT scan. The area of the liver is extracted among separated areas by using information on position and morphology of the liver. Since hepatoma is a hypervascular turner, the area corresponding to hepatoma appears more brightly than the surroundings in contrast-enhancement CT scans, and when hepatoma shows expansile growth, the area has a spherical shape. So, for the extraction of areas of hepatoma, areas being brighter than the surroundings and globe-shaped are selected as candidate ones in an area of the liver, and then, areas appearing at the same position in successive CT scans among the candidates are discriminated as hepatoma. For the performance evaluation of the proposed method, experiment results obtained by applying the proposed method to CT scans were compared with the diagnoses by radiologists. The evaluation results showed that all areas of the liver and liver tumors were extracted exactly and the proposed method has a high availability as an auxiliary diagnosis tools for the discrimination of liver tumors.

A new grafting cactus 'Yeomyeong' was developed by an interspecific crossing between Gymnocalycium marsoneri and G mihanovichii at the National Institute of Horticultural and Herbal Science, Rural Development Administration in 2005. In 2001, an interspecific crossing line '9922012' with orange color was selected from the cross of G. marsoneri ${\times}$ G. mihanovichii 'IG-112'. The line '9922012' as a female parent was crossed with G. mihanovichii 'IG-177', and the orange colored lines were obtained in 2002. The 'Wonkyo G1-159' was selected from the orange colored lines through three times of characteristic evaluation during 2003 to 2005. The 'Wonkyo G1-1 59' was named 'Yeomyeong' in the RDA in 2005. The color of both body and tubercle was orange. The shape of globe was flattened round and it had 7 to 9 ribs. The spine was erect, short sized and grayish brown color. Growth was faster, reaching 41.8-47.7 mm in diameter, than the comparison cultivar 'Hwangwol', at 10 months after planting. The number of tubercle was 6.9-12 per globe. 'Yeomyeong' was developed for export to the America and the Netherlands. Characteristics of the cultivar could be maintained by grafting on the Hylocereus trigomus.
