Purpose: The number of sore patients are increasing steadily, especially in old ages, chronic disease and paralytic patients. Most of patients need to surgical treatment. The aim of this paper is to assess clinical analysis of surgical treatment and to consider operative methods, complications, and recurrences.Methods: We reviewed the data from 82 consecutive patients with 101 pressure sores from March 2003 to May 2006 to discuss the occurrence rate and recurrence rate according to the site on the basis of the presence or absence of paraplegic and its etiology-the patients were categorized into three diagnostic groups: traumatic paraplegics(TP), nontraumatic paraplegics (NTP), and nontraumatic nonparaplegics(NTNP). We examined the sites and sizes of each lesions, patient's state, primary causes of pressure sore, operative methods as each sites and groups, occurrence of complications and recurrences on each groups. Results: In 82 patients, 52 patients were male, 30 patients were female. The male to female ratio was 1.7 :1. Mean age was 55.8 years. 27 patients were in TP group, 35 in NTP group, and 20 in NTNP group, respectively. The common site of sore were sacral area (50.5%), greater trochanteric area(15.8%) and ischial area(13.9%). In each group, incidence rate of recurrence and complication were 11.1%, 40.7% in TP, 5.7%, 5.7% in NTP and 15%, 45% in NTNP. Conclusion: Surgeons must consider the general condition of the patient and possibility of recurrence and returning of daily life. We propose that cutaneous flap, fasciocutaneous flap or skin graft as well as musculocutaneous flap be useful to repair of sore site as each patient's state.
These days, fashion museums that were established during the 60~70s in advanced countries are spiritedly planning opportune exhibitions as well as opening collections and accumulated research materials to the public. They are also publishing innovative visual references and offering various educational programs. They play a crucial role in speeding up the development of creativity of fashion designers by accumulating archives through analytic researches. Since Korea has applied western fashion for over a century, now is the time to make a fundamental long-term plan for establishing the identity of Korean fashion by gathering and classifying the history of a century. Thus, the aim of this study is to reach a conclusion to construct fashion museum in Korea to discover as well as develop fashion talents and eventually enhancing national competitiveness. First, the theoretical study on the history and the functions of fashion museum were analysed. 'The collection & exhibition' in the common thread is one function of the fashion museum. Another function is 'the research', which includes accumulations, classification and record of materials in a particular point of view. It also includes publishing catalogues with temporary exhibitions and open management to the scholars and the designers. 'The communication', which is enacted through various educational programs and events for inflow of new visitors, is the other function of fashion museum. The current state of fashion museums in advanced countries and Korea were also analysed. Korean public museums only owned traditional collections while public fashion museums in other advanced countries usually owned collection of the past and the present together. The only contemporary fashion museum in Korea is run private which leads to many problems. Finally, The study went further to suggest the advanced model of fashion museum in Korea based on the research.

Purpose: The vegetative state is a clinical condition with complete unawareness of self and environment, but with preservation of brain - stem functions. Vegetative patients may have nosocomial infections in their wounds, like pressure sores and infected craniums after cranioplasties. Usually flap surgery is necessary for those wounds, but decision of undergoing surgery is difficult because of various adverse conditions of vegetative patients. We share our experience of several successful flap surgeries in vegetative patients, and evaluate obstacles and requirements to get satisfactory results. Methods: From December 2005 to September 2008, a total of 4 vegetative patients underwent surgeries. In 2 patients with infected artificial craniums, scalp reconstructions with free flaps were performed. In other 2 patients with huge pressure sores with sepsis, island flap coverage of wounds was done. Retrospective study was done on hospital day, vegetative period, number of surgeries done, underlying diseases, causative bacteria, and contents of informed consent. Results: Mean hospital day was 14 months and mean vegetative period was 17.5 months. Patients underwent average of 4.5 surgeries under general anesthesia. There were several underlying diseases like hypertension, DM, CHF and chronic anemia. MRSA(Methicilin - resistant Staphylococcus Aureus) was cultured from every patient's wounds. Informed consent included a warning for high mortality and a need of attentive familial cooperation. Conclusion: There are three requirements for doing flap surgeries in vegetative patients. First, to prevent aggravation of brain damage and underlying diseases by general anesthesia, multidisciplinary team approach is needed. Second, operation should be beneficial for prolonging patient's lifespan. Third, because postoperative care is very difficult and long hospitalization is needed, detailed informed consent and highly cooperative attitude of family should be confirmed before operation.

Dispatch of ROK Armed Forces is a significant contemporary event that enhances the ROK's position in the international communities and ensures the solid national security by contributing international peace keeping operations. Indirectly, dispatch of armed forces also can contribute to strengthen the national defense. However, despite its importance, record management related to the dispatch is not done properly. Because variable records produced in the process of dispatching troops are transferred to distributed archives, searching or accessing each record is not easy and making a collection from a series of record related to certain dispatch is more difficult. Moreover, since most transferred records were produced in the public domain, production and management of record in the aspect of archive of everyday life is needed. In this paper, we summarize the current state of domestic records by dispatch procedure, organization, and dispatched troops. And we also explore the problem of record management.
The effect of poly[2-methacryloyloxyethyl phosphorylcholine] (pMPC) on the skin permeation property was investigated by performing in vitro skin permeation study of a model drug, nicotinic acid (NA). Effect of pMPC polymer in donor solution on skin permeation rates was evaluated using side-by-side diffusion cells. Also, the structural alterations in the stratum corneum (SC), inter-lamellar bilayer (ILB) and dermis layers in pMPC-treated and -untreated skin sections were investigated with transmission electron microscopy (TEM). The permeation profile of NA without pMPC in donor solution showed biphasic mode: initial $1^{st} phase and 2^{nd}$ hydration phase. The sudden, more than 10-fold increase in flux from the initial steady state (43.5 $\mu g/cm^2$/hr) to the $2^{nd}$ hydration phase (457.3 $\mu g/cm^2$/hr) suggests the disruption of skin barrier function due to extensive hydration. The permeation profile of NA with 3% pMPC in the donor solution showed monophasic pattern: the steady state flux (10.9 $\mu g/cm^2$/hr) without abrupt increase of the flux. The degree of NA permeation rate decreased in a concentration-dependent manner of pMPC. TEM of skin equilibrated with water or 2% pMPC for 12 h showed that corneocytes are still cohesive and epidermis is tightly bound to dermis in 2% pMPC-treated skin, while wider separation between corneocytes and focal dilations in inter-cellular spaces were observed in water-treated skin. This result suggests that pMPC could protect the barrier property of the stratum corneum by preventing the disruption of ILB structure caused by extensive skin hydration during skin permeation study.
Purpose: The disinsertion of the phalangeal tendon distal insertion has difficulties in ordinary tenorrhaphy operation for the anatomical features, and still has controversy between non-surgical and surgical management. The purpose of this study is to select treatment for the injury of the phalangeal tendon distal insertion, as we've had a good results from operation treatment with Pull-in suture technique. Methods: We reviewed the hospital records of 12 patients treated with Pull-in suture technique with disinsertion of the phalangeal extensor or flexor tendon distal insertion from June 2006 to June 2007. Eight patients were involved with the tendon disinsertion without bone fracture, and 4 patients were involved with the fracture of the phalangeal tendon distal insertion site. After removal of the K-wire in week 6, active physical exercises were commenced immediately. The mean follow-up period was 12.4 months. Results: All the patients who had tendon disinsertion with bone fracture had IIB, by Wehbe and Schneider's classification 2, and we evaluated the results comparing the same finger of the other hand according to Crawford's evaluation criteria 5. The nine excellent and three good results were obtained and there were no limitation of motor for the patient who had operation for the rupture of flexor tendon as well. There were no particular complications during the follow-up period. Conclusion: The most important thing for the disinsertion of the phalangeal tendon distal insertion is to maintain an accurate and durable reduction state keeping the tension of tendon. At this point, after removal of the K-wire, the Pull-in suture technique allows accurate realignment of the tendon-bone unit without any specific instrumentation under the more stable state. The Pull-in suture technique seems to be a strong alternative for the treatment of disinsertion of the phalangeal tendon distal insertion, with successful treatment outcome(rapid functional recovery and high patient satisfaction).
The pyrrolizidine alkaloids (PAs), contained in a number of traditional remedies in Africa and Asia, show wide variations in metabolism between animal species but little work has been done to investigate differences between animal strains. The metabolism of the PA senecionine (SN) in Fischer 344 (F344) rats has been studied in order to compare to that found in the previously investigated Sprague-Dawley (SO) rats (Drug Metab. Dispos. 17: 387, 1989). There was no difference in the formation of ($\pm$) 6,7-dihydro-7-hydroxy-1-hydroxymethyl-5H-pyrrolizine (DHP, bioactivation) by hepatic microsomes from either sex of SO and F344 rats. However, hepatic microsomes from male and female F344 rats had greater activity in the Noxidation (detoxication) of SN by 88% and 180%, respectively, when compared to that of male and female SD rats. Experiments conducted at various pH showed an optimum pH of 8.5, the optimal pH for flavin-containing monooxygenase (FMO), for SN N-oxidation by hepatic microsomes from F344 females. In F344 males, however, a bimodal pattern was obtained with activity peaks at pH 7.6 and 8.5 reflecting the possible involvement of both cytochrome P450 (CYP) and FMO. Use of specific inhibitors (SKF525A, 1-benzylimidazole and methimazole) showed that the N-oxide of SN was primarily produced by FMO in both sexes of F344 rats. In contrast, SN N-oxide formation is known to be catalyzed mainly by CYP2C11 rather than FMO in SD rats. This study, therefore, demonstrated that there were substantial differences in the formation of SN N-oxide by hepatic microsomes from F344 and SD rats and that this detoxification is catalyzed primarily by two different enzymes in the two rat strains. These findings suggest that significant variations in PA biotransformation can exist between different animal strains.
Hypoxemia is known to induce various physiological changes which can result in alteration in drug pharmacokinetics. To examine the effect of acute moderate hypoxemia on metoclopramide (MCP) pharmacokinetics, a continuous 14-hour infusion of MCP during a normoxemic, hypoxemic and subsequent normoxemic period was conducted in eight adult sheep. Arterial blood and urine samples were collected to examine the effects on the pharmacokinetics of MCP and its deethylated metabolites. MCP and its mono- and di-deethylated metabolites were quantitated using a GC/MS method. Steady-state concentrations of MCP were achieved in each of the three periods. During hypoxemia, MCP plasma steady-state concentration increased significantly from 50.72$\pm$1.06 to 63.62$\pm$1.79 ng/mL, and later decreased to 55.83$\pm$1.15 ng/mL during the post-hypoxemic recovery period. Total body clearance ($CL_{TB}$) of MCP was significantly decreased from 274.2$\pm$48.0 L/h to 205.40$\pm$28.2 L/h during hypoxemia, and later restored to 245.8$\pm$44.2 L/h during the post-hypoxemic period. Plasma mono-deethylated MCP concentration (32.78$\pm$1.73 ng/mL) also increased, compared to the control group (21.20$\\pm$1.39 ng/mL), during hypoxemia and subsequent normoxemic period. Renal excretion of MCP and its metabolites was also decreased during hypoxemia, while urine flow was increased with a concomitant decrease in urine osmolality. Thus, the results indicate that acute moderate hypoxemia affects MCP pharmacokinetics.

Percutaneous absorption and model membrane variations of melationin (MT) in aqueous-based propylene glycol and $2-hydroxypropyl-{\beta}-cyclodextrin $vehicles were investigatted. the excised hairless mouse skin (HMS) and two synthetic ethylene vinyl acetate (EVA) and microporous polyethylene (MPE) were selected as a model membrane. the solubility of MT was determined by phase equilibrium study. the vertical $Franz{\circledR}$ type cell was used for diffusion study. The concentration of MT was determined using reverse phse HPLC system. The MT solubility was the highest in a mixture of PG and $2-HP{\beta}CD$. The percutaneous absorption of MT through excised HMS increased as the solubility increased. However, the permeability coefficient decreased and then slightly increased in mixture of PG and $2-HP{\beta}CD$. On the other hand, both flux and permeability coefficient through EVA membrane decreased as the solubility increased. No MT was detected over 12 h after starting diffusion through MPE membrane. The flux of MT was dependent on the type of membrane selected. Flux of MT was greatest in excised HMS followed by EBA and MPE membrane. Flux of MT through EVA membrane was 5-20 times lower when compared to excised HMS. Interestingly, volumes of donor phase when MPE membrane was used, significantly increased during the study period. the HMS might be applicable to expect plasma concentration of MT in human subjects based on flux and pharmacokinetic parameters as studied previously. the current studies may be applied to deliver MT transdermally using aqueous-based vehicles and to fabricate MT dosage forms.
Rapid development of electronic technology has made it possible to perform various function. But this technology made it increase it's complexity. Therefore, It was important to identify usability problem in interface design. The quality of interface to promote the efficient interaction should be evaluated with regard to users' cognitive characteristics. So, in this paper, washing machine, that is one of the most useful electronic home application was studied menu structure on interface and it's operational states transition. At first, an cognitive menu structure is identified with users' conceptual similarity of the main function of washing machine. Then three washing machines was selected to compare with the cognitive menu structure. And, we were analyzed how operational state of the washing machine was transfered. As a result, we can be revealed that menu operational method based on the cognitive structure was consistent with the user's preferred operational method during the experimental tasks and the users and designers had a different knowledge of an it's function structure. These results will be useful to design the washing machine interface.
