Myxofibrosarcoma represents one of the most common soft tissue sarcomas of the extremities in adult and elderly patients. However, it only rarely occurs in the chest wall. A 58 years old woman presented with a huge painless lump (8 ${\times}$ 6.5 cm) in the right lower parasternal area which recurred a few months following excision from General surgery of our hospital. Histology showed an infiltrative deep seated dermal and subcutaneous tumor. It had a distinctive lobular growth pattern with prominent myxoid change and moderate cellularity. Tumor cells were spindleshaped with varying degrees of pleomorphism and frequent mitotic figures. Numerous blood vessels with curvilinear growth pattern were also seen. Immunostains for S-100, CD68, Mac 387, and FX IIIa were all negative, but positive for Vimentin. The histologic feature was of an intermediate grade myxofibrosarcoma. Wide excision was performed and recovered in good condition without any physical disabilities and was discharged at one month later. Currently she is waiting for the skin graft without chemotherapy and radiotherapy.

The present study was done to determine the efficacy and safety of varicose vein removal using a minimally invasive, powered vein-extracting device with cutaneous transillumination and tumescent anesthesia techniques and then compared this to a retrospective group of conventional phlebectomy operations. There were 133 limbs in 104 patients(72 women, 32 men) treated with the use of the vein extractor aided by transcutaneous illumination. The hydrodissection was performed with Trivex™ Irrigated illuminator(Smith & Nephe $w^{ R}$) system using normal saline after the 2~3mm sized skin incision. Varicose clusters were extracted by the use of TriveTM esector(Smith & Nephe $w^{ R}$) system under transillumination. After the varisoce vein extraction, the operation area was compressed with surgical pad for bleeding control. The complication rate was 3.84% The mean number of incisions was 3.24 and mean operative time per limb was 65.9 minutes. The mean hospitalization was 1.86 days. The varicose vein extraction using transilluminated powered phlebectomy(TIPP) is a safe, efficacious and cosmetically satisfactory method. The procedure decreases the operating time and the number of incisions required to remove varicose clusters. Further evaluation and long term follow up will be necessary to determine the recurrence rate and long termcomplications.to determine the recurrence rate and long termcomplications.

The heel, with its specialized fat for shock absorption at heel strike and large surface area for balance and weight bearing, is a important component of normal ambulation. Despite of distinguished improvement in the field of microsurgical free flaps, the choice of reconstruction of the heel has been remained controversial. We reviewed 22 cases of the heel reconstruction using vascularized free flaps from January, 1980 through May, 1993 at the Department of Orthopedic Surgery of Korea University Hospital. The results were as follows: 1. The etiology was traumatic in 21 cases, and chronic ulceration due to burn in 1. 2. The arteries used in free flaps were 11 dorsalis pedis arteries, 2 deep circumflex iliac arteries, 2 supeficial iliac arteries, 2 branches of lateral femoral circumflex iliac arteries, 2 radial arteries, and 3 thorcodorsal arteries. 3. The mean size of the vascularized bone was $4.5cm{\times}3.5cm$, and that of skin flap was $12.1cm{\times}9.2cm$. 4. Of the 22 cases, 19 had a successful outcome and 3 in failure, the causes of failure were thrombosis and infection.

Background and Objectives : Electroglottography(EGG) is a non-invasive method of monitoring the vocal cord vibration by measuring the variation of physiological impedance across the vocal folds through the neck skin. It reveals especially the vocal fold contact area and is widely used for basic laryngeal researches, voice analysis and synthesis. The purpose of this study is to investigate the effectiveness of EGG parameters in differential diagnosis of laryngeal cancer. Materials and Methods : The author investigated 10 laryngeal cancer and 25 benign laryngeal disease patients who visited at the Department of Otolaryngology, Pusan National University Hospital. The EGG equipment was devised in the author's Department. Among various parameters of EGG, closed quotient(CQ), speed quotient(SQ), speed index(SI), Jitter, Shimmer, Fo were determined by an analysis program made with MATLAB 6.5$^{\circledR}$(Mathwork, Inc.). In order to differentiate various laryngeal diseases from pathologic voice signals, the author has used the electroglottographic parameters using the neural network of multilayer perceptron structure. Results : SQ, SI, Jitter and Shimmer values except those of CQ and Fo showed remarkable differences between benign and malignant laryngeal disease groups. From the artificial neural network, the percentage of differentiating the laryngeal cancer was over 80% in SQ, SI, Jitter, Shimmer except for CQ and Fo. These results indicated that it is possible to discriminate the benign and malignant laryngeal diseases by EGG parameters using the artificial neural network. Conclusion : If parameters of EGG which can reveal for the pathology of laryngeal diseases are additionally developed and the current classification algorithm is improved, the discrimination of laryngeal cancer will become much more accurate.

This study was conducted during the time period of September 1997 to February 1999. in order to provide data concerning important facets of horne care nursing and the degree to which practicing hospital and public health nurses believe themselves to be competent in each area. The study subjects consisted of 610 hospital nurses, 158 public health nurses and 21 other nurses from Seoul and the province of Kyunggi. Korea. Data was collected through self-reporting questionnaires which was used by Kim et al.(1999) to evaluate the status of home health nursing and the varying ideas of self-competence that practicing nurses have. The results of the study were as follows: 1) The mean scores of perceived important components and competencies on home health nursing measured on the Likert 4 point scale were $3.15{\pm}0.36$ for importance. and $2.56{\pm}0.36$ for competency. Of the four categories regarding nursing services, the 'Nursing skill' factor had the highest importance and competency. 2) There were significantly higher scores for hospital nurses' importance components and competencies of home care nursing as compared to those scores for public health nurses. 3) The significant factors of the importance component of home care nursing listed in order of priority were 'general infection control', 'bed sore care skill', 'rehabilitation care', 'keeping maintenance of the client's confidentiality', 'malpractice', 'diabetes patient care', 'ability for problem solving' respectively. In contrast, of low priority in the importance components of home care nursing were 'referring nursing as a job to others'. 'record keeping', 'family dynamics', 'medical equipment', 'economic problems', 'environmental assessment', 'suture removal', 'multidisciplinary coordination' respectively. 4) The high priority of the degree to which practicing nurses believe themselves to be competent in home health nursing were the 'blood sugar test', 'enema skill', 'injection skill', 'skin care', 'bed sore care skill', etc. In contrast, lower competence for home care nursing as perceived by nurses were 'AIDS care', 'family violence care', 'substance abuse care', 'mental health care' respectively.

Topical agents including of steroids are easily exposed to Korean patients in community setting. Those topical agents must be use cautiously because can cause adverse drug reaction unlike other oral medication. We evaluate the using pattern topical agents of Korean in community setting. We performed a questionnaire survey in three different pharmacies (general community pharmacy, dermatology clinic oriented pharmacy, general hospital oriented pharmacy) and in three university town. The survey asked necessity of topical agents, the number of applications per day, application period, site, and exist of steroids ingredient, etc. Total 330 people was participated in the survey from May 1st to July 31st, 2014. We analysed the survey by the frequency of each question and cross-analysis of the compliance between general public and pharmacy groups. In results, Korean people used topical agents for sudden skin diseases (66.9%), was gotten by dermatologist's prescription (89.1%), and did not know their diagnosis (39.2%). The people applied topical agents on face (22.3%), less one half FTU (finger tip unit) per application (61.9%), less than one week (62.9%). Though they was received drug education from pharmacist (52.2%), did not heard about adverse effects (78.4%). And compliance of applied times in pharmacy group was higher than in-non-pharmacy group (56% vs 38%, p=0.002). The highest compliance between 3 pharmacy subgroup was general community pharmacy (76.3% vs 61.6%, 61.2%, p=0.039). Compliance of applied duration was no difference between groups. Majority of respondents did not know diversity of ingredients, potency, application area of topical steroids, and replied to feel some vague reluctance and to think so dangerous about topical steroids. In conclusion, Korean people in community use topical agents well but still some exposed to risk from topical agents.

Purpose: We investigated the clinical characteristics and demographics of patients who suffered from hydrofluoric acid chemical injury and the mechanism of damage. Methods: We retrospectively reviewed the medical records of patients who were exposed to hydrofluoric acid from March 2004 to March 2009 and who were seen at the emergency centers in two university teaching hospitals. Results: Forty four patients out of 47 patients suffered from chemical burn, while the injuries of the remaining 3 could not be identified by the medical records. A total of 17 hydrofluoric acid chemical injury patients were enrolled during the study period, and their mean age was $29.6{\pm}7.0$. All the patients were accidentally injured by contact with the material and none of them inhaled or ingested the material. Only 6 patients wore appropriate protective equipments and 5 underwent the water irrigation for more than 10 minutes. The most common exposure area was the hand and forearm (70.5%). Less than 1% of all of the patients had their total body surface (TBS) exposed to hydrofluoric acid (mean=0.35%). The mean time interval from calcium gluconate administration to pain relief was $33.6{\pm}8.8$ hours. Conclusion: When exposed to hydrofluoric acid, it is important to wear protective equipment and undergo water irrigation for more than 10 minutes. Pain and skin damage were observed in all the patients. After treatment, we concluded that administration of calcium gluconate and pain killers was successful in relieving pain, and the prognosis was also positive for the admitted and followed up patients when less than 1% of the TBS was exposed.

Pacific saury, Cololabis saira kwamaegi, is a traditional local food of the Eastern sea area centering around Pohang. It is well-recognized as being both tasty and nutritious. Nevertheless, bacterial contamination, excessive dryness, and compositional changes have made it edible only during the winter months. Therefore, to improve its storage, this study examined the effects of storage material, type, temperature, and duration on compositional changes in kwamaegi. The studied samples were kwamaegis that had been dried naturally for 15 days. The storage materials included an A-film, a self-developed multi-film made of polyethylene, polyamide, EVOH, and polyethylene; as well as a B-film made of polyethylene, nylon, polyethylene, nylon and polyethylene. The B films were used after pressing and laminating. The storage types included one whole fish(1G), or 2 divided fish(2G), to increase eating convenience. The 2G type was the muscle portion divided vertically after discarding the jowl, skin, and internal organs. The storage temperatures were $0^{\circ}C$, $-15^{\circ}C$, and $-30^{\circ}C$, and the storage durations were 2, 4, and 6 months. Pathogenic bacteria and rheology were measured to observe general compositional changes. The whole kwamaegi showed a total cell number of $1,565{\pm}112$ CFU/100 g flesh, while the divided Kwamaegi showed significantly greater bacterial numbers at $2,031{\pm}145$ CFU/100 g flesh. Psychrophils and halophils increased significantly while coliform were not found; the number of mesophils also increased, but not significantly. There were no significant cell number variations between the A-film and B-film. At $0^{\circ}C$, both the A-and B-films resulted in cell numbers of $115{\sim}212$ CFU/100 g flesh, revealing just $7.3{\sim}10.4%$ of the initial storage levels. Overall, there were no significant differences between the storage materials. Generally, as the storage temperature and duration increased, the moisture content of the kwamaegi decreased. Also, as storage duration and temperature increased, crude protein and crude lipid contents increased; in addition, they increased proportionally as the moisture content of the fish decreased. There were no significant differences in crude ash content with respect to the storage materials, storage temperatures, or storage durations. Finally, there were no significant differences between the kwamaegi samples naturally dried for 15 days and those stored in the B-film vacuum storage for 6 months for strength, hardness, cohesiveness, springiness, gumminess, and water activity.
