The purposes of the study were 1) to segment the female apparel market based on clothing benefits sought by female adualt consumer in Cheju, and 2) to develop a profile of each segment concerning lifestyle, use of information sources, perceived store attributes, store preference and demographics. The data(n=228) were collected via a questionnire from adult females of ages over 20's. Using cluster analysis on benefits sought factors, four groups were identified and labeled as 1) Economic-value oriented users of clothing(24%) : 2) Brand oriented users of clothing(14%); 3) Aesthetics/fashion oriented users of clothing(26%); 4) Easy care oriented users of clothing(36%). ANOVA and Chi-square statistics revealed significant differences among the four groups according to clothing benefits sought factors, lifestyle factors, use of information sources, store attributes perceived on store types, store-type choices, new store-type preferences and demographic variables. A profile of these groups was developed.

The purposes of the study were (1) to segment the female college apparel market based on clothing shopping orientation and (2) to develop a profile of each segment regard to fashion life style, information sources, clothing selection criteria, the importance of store attributes and patronage behavior. The data were collected through questionaire by random sample of 526 female college students. By cluster analysis of shopping orientation factors, four groups were identified(apathetic apparel shopper, highly involved apparel shopper, economic apparel shopper, psycho-socializing apparel shopper). Four groups were then compared through multivariate analysis of variance and chi-square statistics on 3 fashion life style factors, 11 information sources, 10 clothing selection criterias, 9 store attributes and 1 patronage behavior variable. Significant difference were found among the four groups on all these variables which indicate that clothing shopping orientation can be a useful base for segmenting female apparel market and these groups are unique in terms of the above 5 variables.

Objectives : Since vertebroplasty has been introduced, we performed short segment pedicle screw fixation with augmented intra-operative vertebroplasty in patients with unstable thoraco-lumbar fracture. Our intentions are to demonstrate the efficacy and indication of this new technique compare to conventional methods. Material and Methods : The surgery comprised of pedicle screw fixations on one level above and below the fracture site, and the fractured level itself, if pedicle is intact, and intra-operative vertebroplasty under the fluoroscopic guide with in-situ postero-lateral bone graft. Also, in cases of bone apposition, we removed those with small impactor through a transfascetal route. During the last 2 years, we performed in seven(7) unstable thoraco-lumbar fracture patients who consisted of two different characteristics, those four(4) with primary or secondary osteoporosis and three(3) of young and very healthy. All patients were followed clinically by A.S.I.A. score and radiography. Results : Mean follow up period was 14 months. We observed well decompressed state via transfascetal route in cases of bone fragments apposition and no hardware pullout in osteoporotic cases, no poly-methyl-methacrylate (PMMA) leakage through the fracture sites into the spinal canal, and no kyphotic deformities in both cases during follow-up periods. All patients demonstrated solid bony fusion except one following osteoporotic compression fracture on other sites. Conclusions : In the management of unstable thoraco-lumbar fracture, we believe that this short segment pedicle screw fixation with augmented intra-operative vertebroplasty reduce the total length or levels of pedicle screw fixation without post-operative kyphotic deformity.

Objective: To review the characteristics of distal middle cerebral artery (MCA) aneurysm treated by microsurgery, the detailed surgical options, and the clinical result. Methods: We retrospectively reviewed cerebral aneurysm in the M2 and M3 segments of the MCA surgically treated between January 2015 and December 2022. The demographic data, aneurysm-related findings, type of surgical approach, surgical technique, and clinical outcomes of the enrolled patients were analyzed. Results: Sixteen distal MCA aneurysms were treated with microneurosurgery (incidence, 1.0%; female, 12; mean age, 58.1 years; ruptured, three). Twelve aneurysms were in the M2 segment (insular segment), two aneurysms at the M2-M3 junction, and two aneurysms in the M3 segment (opercular segment). Twelve aneurysms were saccular (average size, 4.9 mm; multiplicity, 50%; average aneurysms, 3.0; partially thrombosed, 1; sidewall aneurysm, 2). Three aneurysms were fusiform, of which two were ruptured. Of the ruptured aneurysms, one was a ruptured dissecting aneurysm. The trans-sylvian and trans-sulcal approaches were used in fourteen and two patients, respectively. Neck clipping, wrap clipping, and surgical trapping were performed in twelve, one, and one patient, respectively. Proximal occlusion was performed in one patient. Bypass technique was required in two patients (neck clipping and proximal occlusion). The modified Rankin Score was 6 in the two patients with ruptured aneurysms. The remaining patients did not show further neurological deterioration after microneurosurgery. Conclusions: Distal MCA aneurysms had a high incidence of being diagnosed with multiple other aneurysms and were relatively non-saccular.

Pulmonary artery aneurysm is Behcet`s disease is rare and can be fatal due to rupture. We experienced a case of pulmonary artery aneurysm in Behcet`s disease. The patient was 21 year old woman who was adimitted with three month history of dyspnea, fever and cough. On examination, she had aphthous ulcer in the mouth and erythema nodosum on the left popletial fossa and forearm, but didn`t have any lesion at eyes and genitalia. The latex fixation test for rheumatoid factor, VDRL test for syphillis, antinuclear antibody and LE cell test were all negatives. The third and fourth components of complement in the serum, serum immunoglobulin concentrations[IgG, IgM, IgA] were within normal range. The chest radiography revealed a 5x6cm sized radiopaque mass density in the left hilar region. Two months later, the mass was enlarged to 6x7cm. The IV-DSA showed a single aneurysm at the proximal part of left lower lobe artery with lingular segment artery and no distal perfusion by thombotic obstruction. The steroid therapy was done for a month, but symptoms not improved. We performed resection of lingular segment and lower lobe including the aneurysm. The microscopic findings of the operative specimen were intimal hyperplasia and fragmentation of the internal elastic fibers. She was improved without remarkable event, except infection of the operative wound.

In order to elucidate the growth mechanism of sulfide chimney formed as a result of seafloor hydrothermal mineralization, we carried out the mineralogical and fluid inclusion studies on the inactive, sulfide- and silica-rich chimney which has been recovered from a hydrothermal field in the Cleft segment of the Juan de Fuca Ridge. According to previous studies, many active and inactive vents are present in the Cleft segment. The sulfide- and silica-rich chimney is composed of amorphous silica, pyrite, sphalerite and wurtzite with minor amounts of chalcopyrite and marcasite. The interior part of the chimney is highly porous and represents a flow channel. Open spaces within chimneys are typically coated with colloform layers of amorphous silica. The FeS content of Zn-sulfides varies widely from 13.9 to 34.3 mole% with Fe-rich core and Fe-poor rims. This variation possibly reflects the change of physicochemical characteristics of hydrothermal fluids. Chemical and mineralogical compositions of the each growth zone are also varied, possibly due to a thermal gradient. Based on the microthermometric measurements of liquid-rich, two-phase inclusions in amorphous silica that was precipitated in the late stage of mineralization, minimum trapping temperatures are estimated to be about 1140 to 145$^{\circ}$C with the salinities between 3.2 and 4.8 wt.% NaCI equiv. Although the actual fluid temperatures of the vent are not available, this study suggests that the lowtemperature conditions were predominant during the mineralization in the hydrothermal field at Cleft segment. Comparing with the previously reported chimney types, the morphology, colloform texture, bulk chemistry, and a characteristic mineral assemblage (pyrite + marcasite + wurtzite + amorphous silica) of this chimney indicate that the chimney have been formed from a relatively low-temperature (<250$^{\circ}$C) hydrothermal fluid that was changed by sluggish fluid flow and conductive cooling.

S/W product line is a S/W product or a set of S/W system, which has common functions. We can develop a specific S/W product, which satisfiesrequirements of a particular market segment and a mission in a specific domain by reusing the core asset such as the developed S/W architecture through the S/W product line. S/W development methodology based on the S/W product line can develop a S/W more easily and fast by reusing the developed S/W core asset. An advanced country of S/W technology selects S/W product line as a core field of S/W production technology, and support technology development. In case of USA, CMU/SEI (Carnegie Mellon University / Software Engineering Institute) developed product-line framework 4.0 together with the industry and the Ministry of National Defense. Europe is supporting the development of product line technology through ITEA(IT for European Advancement) program. In this paper, we aim to construct reference architecture of S/W product line for production of the S/W product line.

The purpose of this study is to evaluate the incidence of endometriosis and tuboperitoneal fistula in remaining tubal segments after tubal ligation. We reviewed 936 tubes which were obtained from 474 patients who received tubal reanastomosis in the Department of Obstetrics and Gynecology in Seoul National University from June, 1980 to June, 1986. The results were as follows: 1. The incidence of tuboperitoneal fistula was 9.31% of the total 936 tubes (87 tubes) and cautery was the most frequent technique of sterilization in fistula formation (15.20%). 2. The incidence of tubal endometriosis was 2.03% of the total 936 tubes (19 tubes) and cautery was the most frequent technique of sterilization in the development of tubal endometriosis (2.73%). 3. The incidence of tuboperitoneal fistula in the remaining proximal tubal segment within 4 cm was 11.25% and the incidence of endometriosis in the remaining proximal tubal segment above 4cm was 5.54%. 4. The incidence of tuboperitoneal fistula within 3 yrs after tubal ligation was 11.92% and the incidence of endometriosis over 6 yrs after tubal ligation was 5.73%.

In this study, we evaluated spinal stability based on the change in the thoracolumbar fixation segment using finite element analysis (FEA). To accomplish this, a finite element (FE) model of a normal thoracolumbar spine (T10-L4), including intervertebral discs (IVD), ligaments, and facet joints, was constructed, and the material properties reported in previous studies were implemented. However, L1 was assumed as the lesion site, and three types of posterior fixation, namely, L1-L2, T12-L2, and T12-L1-L2, were implemented in the thoracolumbar FE model. In addition, the loading conditions for flexion, extension, lateral bending, and axial rotation were adopted. Through the series FEA, the deformation, equivalent stress, range of motion, and moment on the pedicle screws, vertebrae, and IVD were calculated, and the spinal stability was evaluated based on the FEA results.
