Purpose: The purpose of this study was to identify the causes, symptoms, and complications of hypoproteinemia to prevent hypoproteinemia and provide appropriate treatment to children with atopic dermatitis. Methods: Children diagnosed with atopic dermatitis with hypoproteinemia and/or hypoalbuminemia were retrospectively reviewed. The patients' medical records, including family history, weight, symptoms, treatment, complications, and laboratory test results for allergies and skin cultures, were examined. Results: Twenty-six patients (24 boys) were enrolled. Seven cases had growth retardation; 7, keratoconjunctivitis; 6, aural discharges; 5, eczema herpeticum; 4, gastrointestinal tract symptoms; and 2, developmental delays. In 21 cases, topical steroids were not used. According to the blood test results, the median values of each parameter were elevated: total IgE, 1,864 U/mL; egg white-specific IgE, $76.5kU_A/L$; milk IgE, $20.5kU_A/L$; peanut IgE, $30kU_A/L$; eosinophil count, $5,810/{\mu}L$; eosinophil cationic protein, $93.45{\mu}g/L$; and platelet count, $666.5{\times}10^3/{\mu}L$. Serum albumin and total protein levels decreased to 2.7 g/dL and 4.25 g/dL, respectively. Regarding electrolyte abnormality, 10 patients had hyponatremia, and 12, hyperkalemia. Systemic antibiotics were used to treat all cases, and an antiviral agent was used in 12 patients. Electrolyte correction was performed in 8 patients. Conclusion: Hypoproteinemia accompanying atopic dermatitis is common in infants younger than 1 year and may occur because of topical steroid treatment continuously being declined or because of eczema herpeticum. It may be accompanied by growth retardation, keratoconjunctivitis, aural discharge, and eczema herpeticum and can be managed through skin care and topical steroid application without intravenous albumin infusion.

Bump mapping is a technique that represents the detailed parts of the object surface, such as a perturberance of the skin of a peanut, using the geometry mapping without complex modeling. However, the hardware implementation for bump mapping is considerable, because a large amount of per pixel computation, including the normal vector shading, is required. In this paper, we propose a new bump mapping algorithm using the polar coordinate system and its hardware architecture. Compared with other existing architectures, our approach performs bump mapping effectively by using a new vector rotation method for transformation into the reference space and minimizing illumination calculation. Consequently, our proposed architecture reduces a large amount of computation and hardware requirements.

This study was designed to investigate clinical features, allergy-inducing substances as well as foods, and nutritional behavior of allergic patients. Sixty-eight adult male and 78 adult female patients were surveyed by using the self-developed questionnairs. The results were as follows: 1. The common target organs of allergic symptoms included bronchus, skin and nose. 2. 37.7% of the subjects did not recognize their allergy inducing substances. Among the known substances, house-dust mite, food, temperature and weather change, pollens, smoke, air pollution materials, drugs and even stress provoked symptoms. 3. As for the food allergy, a number of foods were found to be implicated in allergic reactions. These foods included pork, chicken, seafoods such as mackerel, crab & shrimp, milk, egg, peanut, apple and pupa. Symptoms and signs of food reactions included urticaria, asthma, and rhinitis. 4. The nutrition adequacy ratio (NAR) of energy was below 0.75 for male patients and about 0.80 for female patients. And 24.0% of the subjects were regarded as excellent, 31.5% as fair, and 44.5% as poor in food related behavior evaluation.

Objectives: We examined the common allergenic foods, symptoms and management of food allergies in children attending the facilities registered at Center for Children's Foodservice Management in Gangdong-gu, Korea. Methods: The survey was conducted among the directors or head teachers of 186 children's food service facilities with 7,591 children in 2019. The questionnaire consisted of three parts, including general information about food service facilities, information related to food allergies and allergenic foods and symptoms in individual children. Results: The number of children with food allergy was 271 (3.6%), and the proportion decreased with the increase of age. There were 91 children (33.6%) with a medical certificate, and these children had a significantly higher number of allergenic foods and symptoms than those without a medical certificate. Allergenic food groups included meat, fish, eggs and legumes (59.1%), fruits (12.4%), milk and dairy products (8.9%), cereals (7.8%), vegetables (6.2%), processed foods (3.8%) and oils and sugars (1.9%). Eggs accounted for 22.1%, followed by peanut and tree nuts (18.6%), fruits (12.4%), milk and dairy products (8.9%), shellfish (8.6%), vegetables (6.2%), fish (5.7%), cereals (4.3%) and meat (1.1%). The common allergenic foods were eggs, peanuts, walnuts, kiwi, shrimp, milk, tomatoes, mackerel, blue-green fish, peaches, shellfish (clams and abalone), buckwheat, wheat and soybeans. The most common allergic symptoms were skin and mucous membrane symptoms, such as hives, rash, itching and oral angioedema. Meal management for children with food allergies showed different trends depending on the causative food. Conclusions: The objective diagnosis by an allergist should be done for food allergy management in children's catering facilities. A system for systematic meal management of causative foods should be prepared.

This study compared the physicochemical properties of edible insect oils from silkworm (Bombyx mori) pupa (SP), sago palm weevil (Rhynchophorus ferrugineus) larva (PW), and bamboo caterpillar (Omphisa fuscidentalis; BC) to oils from chicken skin (CK), beef back fat (BF), pork back fat (PF), salmon belly (SB), sea bass belly (BB), coconut (C), and peanut (P). The fatty acid profiles and thermal behaviors (crystallization and melting) of the extracted oils were evaluated. PW and BC oils had more saturated fatty acids (SFAs) than CK, PF, SB, BB, and P oils. SP oil had equivalent SFA content to CK and BB oils. Insect oils exhibited similar monounsaturated fatty acid concentrations in all samples, except C oils. PW and BC oils exhibited a higher content of palmitoleic acid than the other oils. SP oils contained polyunsaturated fatty acids similar to those in SB and BB oils, which were higher than those in PW, BC, CK, BF, and PF oils. SP oil also exhibited the highest concentration of α-linolenic acid (C18:3 n-3). Arachidonic acid (0.01-0.02 g/100 g) in all insect oils was lower level compared to CK, BF, PF, SB, and BB oils. SP oil (0.03 g/100 g) exhibited a slightly higher level of eicosapentaenoic acid compared to PW (0.01 g/100 g) and BC (0.01 g/100 g) oils. The insect oils were liquid at ambient temperature, solid below -15℃, and required less energy (∆H_m-max) for melting than other samples. This study indicated that insects, particularly SP, could serve as an alternative source of fat to meet its growing demand.

Gamma-irradiated peanuts, Korean and Chinese origins, were investigated on detection properties by thermoluminescence (TL), electron spin resonance (ESR), and DNA comet assay (single cell gel electrophoresis). TL measurement showed that the non-irradiated sample revealed a glow curve with low intensity at about 25$0^{\circ}C$, while the irradiated samples showed higher intensity around at 18$0^{\circ}C$. TL ratio (TL$_1$/TL$_2$) of area for TL$_1$ glow curve to TL$_2$ was below 0.05 for the non-irradiated sample and 0.2 or more for the irradiated ones, thus identifying each other. ESR spectroscopy for the irradiated peanuts using outer skin showed negligible signals induced by irradiation, indicating ESR is little applicable to the detection of irradiated peanuts. In DNA comet assay, the non-sample had no or very short tails, whereas the irradiated samples revealed the cells with long tails. Significance in the increase of their lengths depending on irradiation dose (r=0.761/Korean, r=0.768/Chinese) was also found. There was no remarkable difference in detection properties by origins of samples in all determinations, It is concluded that TL analysis or DNA comet assay is suitable for detection of irradiated peanuts and a combined method is recommendable for enhancing the reliability of detection results.

Purpose: Pollen-food allergy syndrome (PFAS) is an immunoglobulin E (IgE)-mediated allergy in pollinosis patients caused by raw fruits and vegetables and is the most common food allergy in adults. However, there has been no nationwide study on PFAS in Korea. In this study, we investigated the prevalence and clinical characteristics of PFAS in Korea. Methods: Twenty-two investigators participated in this study, in which patients with allergic rhinoconjunctivitis and/or bronchial asthma with pollen allergy were enrolled. The questionnaires included demographic characteristics, a list of fruits and vegetables, and clinical manifestations of food allergy. Pollen allergy was diagnosed by skin prick test and/or measurement of the serum level of specific IgE. Results: A total of 648 pollinosis patients were enrolled. The prevalence of PFAS was 41.7% (n = 270). PFAS patients exhibited cutaneous (43.0%), respiratory (20.0%), cardiovascular (3.7%) or neurologic symptoms (4.8%) in addition to oropharyngeal symptoms. Anaphylaxis was noted in 8.9% of the PFAS patients. Seventy types of foods were linked to PFAS; e.g., peach (48.5%), apple (46.7%), kiwi (30.4%), peanut (17.4%), plum (16.3%), chestnut (14.8%), pineapple (13.7%), walnut (14.1%), Korean melon (12.6%), tomato (11.9%), melon (11.5%) and apricot (10.7%). Korean foods such as taro/taro stem (8.9%), ginseong (8.2%), perilla leaf (4.4%), bellflower root (4.4%), crown daisy (3.0%), deodeok (3.3%), kudzu root (3.0%) and lotus root (2.6%) were also linked to PFAS. Conclusions: This was the first nationwide study of PFAS in Korea. The prevalence of PFAS was 41.7%, and 8.9% of the PFAS patients had anaphylaxis. These results will provide clinically useful information to physicians.
