Late complications of head and neck cancer survivors include neck muscle atrophy and soft-tissue fibrosis. We present an autopsy case of neck muscle atrophy and soft-tissue fibrosis (sternocleidomastoid, omohyoid, digastric, sternohyoid, sternothyroid, and platysma muscles) within the radiation field after modified radical neck dissection type I and postoperative radiotherapy for floor of mouth cancer. A 70-year-old man underwent primary tumor resection of the left floor of mouth, left marginal mandibulectomy, left modified radical neck dissection type I, and reconstruction with a radial forearm free flap. The patient received adjuvant radiotherapy. The dose to the primary tumor bed and involved neck nodes was 63 Gy in 35 fractions over 7 weeks. Areas of subclinical disease (left lower neck) received 50 Gy in 25 fractions over 5 weeks. Adjuvant chemotherapy was not administered.

Purpose: This study was conducted to analyze the discourse of puberty in the early teenage girls. Method: The participants were 24, 11-15years old girls who were interviewed in face-to-face using a semi-structured questionnaire. The interviews were done between October 29 and December 27 2003. Analysis of the qualitative data was done in 2 steps. Results: First, the theme of the girls' puberty discourse was identifying normality and consisted of 5 categories : i) defining puberty as experiencing changes, ⅱ) acknowledging their own puberty connecting it with their definitions of puberty, ⅲ) selectively excluding/recognizing the actual pubertal changes by seeing themselves as nonsexual and negative beings, ⅳ) recognizing the pubertal changes as becoming women and making them not peculiar but normal, and ⅴ) sharing the knowledge and experience of change inactively and exclusively and resisting the dominant discourse. Three main discourse frames, marking off sexual/nonsexual, man/women, and major/minor were revealed in the second step of the analysis. They were intricately woven with each other and converged on sex. Conclusion: The girls posited themselves as being asexual, unstable, and marginal. So there is a need to help them recognize their pubertal state as physical and mental paradigmatic changes and assure their pubertal changes as positive.

Hemodialysis is a way of treatment for the patients with acute and chronic renal failure. "Marginal man" depicts the enormous amount of stress that hemodialytic patients suffer. It is known that family with chronic illness get stressed along with the patients and they need nursing care also. This qualitative study was conducted in order to identify the family adaptation process in patients with hemodialysis. 6 dyads of hemodialytic patients and caregivers were interviewed for this research. By way of grounded theoretical strategy the data was collected from October 20, 1999 to November 20, 1999. at a hemodialytic unit that was located in Iksan, Chonbuk by the researcher. The main research questions were "What's the adaptation experience of a patient since after being received with hemodialysis?" to the patients, and "What's the family adaptation experience of hemodialysis?" to the caregivers. The collected data was analyzed by grounded theoretical strategy built by Glaser & Strauss in 1967. Results were as follows; 7 grounded concepts were observed from the patients with hemodialysis and 4 grounded concepts were found from the caregivers. Two categories were derived ; 1) Holding hope that is related with treatment 2) Changing a value system.

The tumor in accessory parotid gland (APG) is rarely occurred and its incidence is about 7.7% of all parotid gland neoplasms, but has a higher frequency of malignancy than major salivary glands. The mucoepidermoid carcinoma is the most common malignancy in APG, while B-cell lymphoma is less than 2%. It is often appeared as superficial mass in mid-cheek area. This lesion requires differential diagnosis with epidermoid cyst, lipoma, neurogenic tumors, Stensen's duct stone, lymphadenopathy and hemangioma etc. The mucosa associated lymphoid tissue (MALT) lymphoma, which is also termed extra-nodal marginal zone B-cell lymphoma tends to be localized disease for long time and has a relatively indolent course. We recently encountered a 69-year-old man with superficial solitary mass on the right cheek area that finally diagnosed as MALT lymphoma in APG. We report the rare and unique case with brief literature review.

Many antinutritional and toxic factors abound in tropical seeds, which are also generally rich in nutrients and therefore more prone to attack from herbivores. Antinutritional and toxic factors are considered to defend seeds against environmental vagaries and thus help to protect them. These factors though good for the plant, cause deleterious effects or are even toxic to animals and man. The conventional seeds cultivated for oil or non-oil purposes, and general aspects of antinutritional factors are not presented here as these have already been discussed widely by many workers. Deficits in conventional protein and energy sources in the tropics have stimulated a quest for alternative feeds both for animals and humans. This article attempts to highlight two new oilseed crops, Jatropha curcas and Moringa oleifera, and in addition deals with some under-utilized seeds with potential as animal feed. Most of these seed plants are adapted to various marginal growing conditions in the tropics and can help to mitigate the prevailing deficit in protein and energy sources. Antinutritional and toxic factors in seed or seed meal, various approaches to detoxify seed meal, and future research and development priorities for their exploitation as animal feeds are presented.

The zinc intake and status of South Koreans from rural, urban and metropolitan areas were compared to evaluate the zinc nutritional status in different regional areas in South Korea. The dietary habits of 721 healthy adult subjects (271 from rural, 240 from urban, 210 from metropolitan city) with an age range 30 ∼ 64 (mean age 54$\pm$18) were assessed using a food frequency questionnaire. Mean daily Zn intake for rural, urban, and metropolitan areas was 6.5 mg, 7.3 mg, and 11.4 mg (p<0.05), respectively, which was 54%,61% and 95% of the Korean RDA for man (12 mg/d). Mean phytate: zinc molar ratios for rural, urban, and metropolitan city were 41, 34, and 30, respectively (p < 0.05), which were higher than the cutoff level of 20 for poor zinc status. The zinc intake and phytate: Zn molar ratio in the rural area were 0.5 and 1.3-fold compared to those of the metropolitan city, which can cause poor zinc nutriture in the rural area. Most of the zinc biomarkers were lower in the rural area than in the metropolitan city (p < 0.05) (mean rural and metropolitan values for plasma Zn: 80.8 $\mu\textrm{g}$/dL and 119.8 $\mu\textrm{g}$/dL, respectively; RBC Zn: 7.8 $\mu\textrm{g}$/dL and 8.8 $\mu\textrm{g}$/dL, respectively; plasma alkaline phosphatase (ALP) activity: 87 mU/mL and 100.4 mU/mL, respectively). It seems that a lower zinc intake in the rural area decreased zinc biomarker levels, such as plasma and RBC zinc, and plasma alkaline phosphatase activity, and caused the poor zinc nutritional status in this area. Most of the zinc biomarkers, such as RBC zinc and urinary and plasma zinc levels, in the subjects from the three localities, were within the normal range even when zinc intake of rural and urban subjects was low. The exception was plasma ALP activity in the rural area, which was lower than the reference level. Thus, marked zinc deficiency in these subjects were not observed, however, the potential for marginal zinc deficiency should be considered, especially for the rural area, because of the low zinc intake and the biomarker levels for marginal zinc deficiency.

Objective : This prospective study sought to verify the stability of three types of short implants measuring 7mm or less. Materials and methods : Implants measuring 7mm or less were placed in patients at multicenter dental clinics in Korea, China, Taiwan, and Singapore. Initial stability, intraoperative and postoperative complications, crestal bone loss, and survival rate of the implant were prospectively evaluated. Results : The primary stability of a 6-mm implant was lower than that of a 7-mm implant. The marginal bone loss of short implants measuring less than 7mm was minimal. Complications such as wound dehiscence, implant mobility, and peri-implant mucositis developed, and these were associated with initial implant failure. The short-term survival rate of 6-mm implant was 93.7%, and that of 7-mm implant, 96.6%. Conclusion : Short implant for the mandible with insufficient height for the residual ridge can be selectively used. Poor primary stability and wound dehiscence can cause osseointegration failure and alveolar bone loss.

Objectives: We investigated the clustering of selected lifestyle factors (cigarette smoking, heavy alcohol consumption, lack of physical exercise) and identified the population characteristics associated with increasing lifestyle risks. Methods: Data on lifestyle risk factors, sociodemographic characteristics, and history of chronic diseases were obtained from 7,694 individuals ${\geq}20$ years of age who participated in the 2005 Korea National Health and Nutrition Examination Survey (KNHANES). Clustering of lifestyle risks involved the observed prevalence of multiple risks and those expected from marginal exposure prevalence of the three selected risk factors. Prevalence odds ratio was adopted as a measurement of clustering. Multiple correspondence analysis, Kendall tau correlation, Man-Whitney analysis, and ordinal logistic regression analysis were conducted to identify variables increasing lifestyle risks. Results: In both men and women, increased lifestyle risks were associated with clustering of: (1) cigarette smoking and excessive alcohol consumption, and (2) smoking, excessive alcohol consumption, and lack of physical exercise. Patterns of clustering for physical exercise were different from those for cigarette smoking and alcohol consumption. The increased unhealthy clustering was found among men 20-64 years of age with mild or moderate stress, and among women 35-49 years of age who were never-married, with mild stress, and increased body mass index (>$30\;kg/m^2$). Conclusions: Addressing a lack of physical exercise considering individual characteristics including gender, age, employment activity, and stress levels should be a focus of health promotion efforts.

In order to fast predict the wind-driven current in a small bay, a convolution method in which the wind-driven current can be generated only with the local wind is developed and applied in the idealized bay and the idealized Sachon Bay. The accuracy of the convlution method is assessed through a series of the numerical experiements carried out in the jidealized bay and the idealized Sachon Bay. The optimum response function for the convolution method is obtained by minimizing the root man square (rms) difference between the current given by the numerical model and the current given by the convolution method. The north-south component of the response function shows simultaneous fluctuations in the wind and wind-driven current at marginal region while it shows "sea-saw" fluctuations (in which the wind and wind-driven current have opposite direction) at the central region in the idealized Sachon Bay. The present wind is strong enough to influence on the wind-driven current especially in the idealized Sachon Bay. The spatial average of the rms ratio defined as the ratio of the rms error to the rms speed is 0.05 in the idealized bay and 0.26 in the idealized Sachon Bay. The recover rate of kinetic energy(rrke) is 99% in the idealized bay and 94% in the idealized Sachon Bay. Thus, the predicted wind-driven current by the convolution model is in a good agreement with the computed one by the numerical model in the idealized bay and the idealized Sachon Bay.achon Bay.

Purpose: Lymphoma originated from mucosa associated lymphoid tissue(MALT) is most common in gastrointestinal system, and rarely found in salivary gland, thyroid, bronchus or orbit. We experienced a case of MALT lymphoma which was originated from conjunctiva and involving lower eyelid without metastasis. Methods: A 40-year-old man suffered palpable mass on right lower eyelid without pain. Orbital computed tomographic and ultrasonographic findings showed a conical mass($1.9{\times}1.2{\times}0.9cm$ size) inside lower eyelid. The mass was completely excised under local anesthesia and histopathological examination was followed. Results: Microscopic finding showed a multiple follicular colonization. In the follicle, small lymphocytes and plasma cells differentiated to centrocyte-like cell, monocyte B cell, plasma cell were diffusely infiltrated. Immunophenotyping was preformed on fixed section. The majority of the small cells were immunoreactive for the B cell marker CD20. Based on the typical histological findings supported by immunostaining, the mass was defined as MALT lymphoma. After excision, SPECT, abdominal CT was carried out and there were no evidence of extraorbital disease. Conclusion: Biopsy and pathological examination should be performed in patients who complain palpable mass on lower eyelid because of possibility of MALT lymphoma. Although MALT lymphoma is rarely metastasized, it is necessary to evaluate the extraorbital involvement using SPECT or other radiologic exams. For detecting extraorbital involvement, periodic follow-up examination is need.
