Abstraction is the cornerstone of ideal software engineering (SWE). This paper discusses a problem of forming reasonable generalizations, representations and descriptions in various software development processes through the prism of poor-quality (rash, unconsidered, uncertain and harmful) abstractions. To do this, emphasis is made on an induced strategic connection between the required abstraction and its compact specific formulation based on existing research and the author's introspective experience. A software aim point and characteristic preservation of the solution integrity is the subject of the best formulation and a program module or code associated with it. Moreover, a personal attitude expressed by personal interest, motivation and creativity, is proclaimed to be a fundamental factor in successful software development.

There were growing reports of herpes zoster reactivation after the coronavirus disease 2019 (COVID-19) vaccination, including a more severe form, herpes zoster ophthalmicus (HZO). A 35-year-old male presented HZO in his left V1 dermatome 10 days after his COVID-19 vaccine booster with Moderna (messenger RNA-1273). He had no history of chronic disease, immunocompromised, autoimmune, malignancy, or long-term immunosuppressive drug use. The rash improved without any further complications after being treated with oral valacyclovir for 7 days. This was a unique case of HZO after the COVID-19 vaccine in a booster setting in healthy younger adults. The association of herpes zoster after a COVID vaccine remained inconclusive and potentially coincidental, especially without the known risk factor. However, we would like to add a report to increase awareness among physicians and the general population, for early recognition and treatment with an antiviral.

Purpose : Juvenile dermatomyositis (JDM) is the most common of the idiopathic inflammatory myopathies in children. The purpose of this study is to observe demographic, initial presentations, duration of time between disease onset and diagnosis, clinical manifestations and laboratory findings at diagnosis of patients with JDM. Methods : Forty seven patients identified at Seoul National University Children's Hospital from January 1986 to May 2007. Medical records were reviewed retrospectively focusing on initial presentations, clinical manifestations and laboratory findings at the time of diagnosis of patients with JDM. Results : Male and female patients were 25 and 22, respectively and sex ratio was 1.14:1. The average age at the time of diagnosis was 6.51 years. Skin rash (94%) was the most common symptom, followed by the proximal muscle weakness (89%). The disease activity score was 10.8. The duration between the onset of the skin rash and the muscle weakness and diagnosis was 7.18 and 4.70 months, respectively. The serum muscle enzymes, LDH, AST, CK and aldolase, were elevated in the patient with JDM. Autoimmune antibodies, antinuclear antibody, anti SSA antibody and anti SSB antibody, were negative findings. Electromyography findings were consistent with JDM in 88% of the patients, the muscle biopsy was in 91% and all MRI findings were compatible with those of patients with JDM. The most common symptom besides musculocutaneous lesions was the calcinosis (62.5%). The most common site of calcinosis was the pelvic area and buttocks. Conclusion : This study shows that the major symptoms are proximal muscle weakness and cutaneous lesion, and they are important to diagnose JDM.

In order to find out the sex- and age-related prevalence rate of allergic diseases in the community. as well as the causes of those diseases. questionnaires were given to 2.415 subjects (1.206 males and 1.209 females) from May to June. 1998. As a second stage. skin tests were given to 452 of the original subjects between July and August. 1998. Finally. from March to November 1999. the results of the tests were compared with those of other countries to make a comparative analysis of epidemiological research on allergic diseases. The results of this study were as follows: The frequency of allergic symptoms by sex was 50.1% in males and 56.7% in females. respectively, which displayed significant difference between males and females(p<.01). By age, the frequency of allergic symptoms in males was highest for those under the age of 9 at 60.6%, whereas in females the highest frequency was between the ages of 30 to 39 at 75.1 %. The relationship between economic level of the subjects and their frequency of allergic diseases showed significant difference (P<.05). There was a high degree of correlation between family history and the frequency of allergic diseases(P<.01). In allergic symptoms, the highest prevalence in both males and females occurred with urticaria, itch and skin rash (33.6% with males and 38.0% with females). Rhinitis, nasal blocking and sneezing had the second highest frequency in both sexes (11.8% of males and 14.0% of females). With regard to the causes of allergic symptoms among the people with allergies, the rate in males was 30.1% in food. 25.0% in pollen, and among females the rate was 30.7% in food, 26.6% in pollen. The frequency of food allergies by sex was 25.6% in males and 25.8% in females, with little difference between males and females, and by age, males of the ages between 40 to 49 and females of the ages between 30 and 39 showed the highest frequency, 31.8% and 32.6% respectively. Among 585 people with food allergies, the sympoms occurring with the allergy in males were 81.5% with urticaria, itch and skin rash. 5.9% with diarrhea and stomachache, and 5.2% with rhinitis, nasal blocking and sneezing. Among females with food allergies, the symptoms were 82.6% with urticaria, itch, skin rash, 9.1% with diarrhea and stomachache, and 4.7% with rhinitis, nasal blocking and sneezing. The type of food most often causing allergy in males was mackerel (6.6%) and females peaches (7.4%). In respect to a positive rate in the skin test by sex, of the 379 males taking the skin test, 21.4% were positive for allergies, whereas 14.7% of the 346 females tested were positive. Among food items found to cause positive allergic reactions, hops had the highest frequency in males (58.9%) and whole eggs had the greatest effect on females (36.4%). The estimated prevalence of food allergies in terms of skin tests was 5.0% of 1.206 males and 3.6% of 1.209 females. In the estimated frequency of food allergy by age group, males of the ages between 40 and 49 and females of the ages from 30 to 39 had the highest rate (6.5% with males and 4.5% with females). In a comparative analysis of epidemiological research on allergic diseases by country group, allergic diseases occurred in 18-50% of each population studied, and the occurrence of allergic diseases when categorized according to symptoms displayed the following as such: allergic rhinitis (3.8-52%), allergic asthma (1.6-17%), and atopy dermatitis (0.33-20.4%). The prevalence of food-related allergies was 6.6-64.9% and the foods causing allergies frequently included milk, eggs, eggs, peanuts, fish, etc.

Purpose: Henoch-$Sch{\ddot{o}}nlein$ purpura (HSP) is a small-vessel vasculitic disease that most often affects the skin. Abdominal symptoms precede the typical purpuric rash of HSP in 14~36%. It is a challenge to diagnose HSP in the absence of a rash, because there are no biologic tests that can identify HSP with certainty, so we tried to find out the characteristic features of HSP gastroenteropathy without purpura before diagnosis. Methods: This study included 82 children with HSP who had been admitted or visited outward of the Department of Pediatrics, Pusan National University Hospital from 1995 to 2000. The cases that the onset of purpura preceded or coincided that of abdominal pain were defined as purpura-positive group. The cases that the onset of abdominal pain preceded purpura more than 1 week and purpura was not presented till diagnosed as HSP gastroenteropathy were defined as purpura-negative group. We compared and analyzed the clinical features of the two groups by reviewing the medical records retrospectively. To ensure the diagnosis of HSP gastroenteropathy, we conducted upper GI series, abdominal ultrasonogram, abdominal CT, endoscopy and/or skin biopsy. Results: The number of cases of purpura-positive group and purpura-negative group were 72 and 10, respectively. There is no difference between two groups in the incidence of clinical symptoms and laboratory findings. Children with HSP gastroenteropathy had characteristic erosive or ulcerative lesions in the stomach or duodenum on esophagogastroduodenoscopy, or mural thickening of the small bowel on abdominal ultrasonogram, CT or upper GI series. Skin biopsy revealed leukocytoclastic vasculitis in 3 of them, although biopsy specimen was taken from any areas of normal- appearing skin. In purpura-negative group, 9 patients improved by steroid therapy. Conclusion: In purpura-negative group, there is no diagnostic feature on the laboratory findings and clinical features. Therefore, to diagnose HSP gastroenteropathy in patients with abdominal pain in the absence of the characteristic rash, careful observation of clinical features and laboratory data, and prompt application of available diagnostic tools such as gastrointestinal endoscopy, radiologic study and skin biopsy are recommended. Early use of corticosteroid may reduce the suffering in these patients.

Purpose : Systemic lupus erythematosus (SLE) is a chronic multisystemic autoimmune disease with complex clinical manifestations. It probably involves genetic, environmental and immunologic factors. In this study, we investigated the clinical manifestations, laboratory findings and prognosis of pediatric SLE to aid clinical care of pediatric SLE. Methods : The data of 45 patients who were diagnosed as pediatric SLE in Severance Children's Hospital from Jan. 1996 to Dec. 2005 were analysed retrospectively. Results : The mean age at diagnosis was 10.8 (0-15) years old. And the ratio of male to female patients was 1:4. The initial manifestations were facial edema (51.1 percent), malar rash (44.4 percent), and fever (28.9 percent). The ANA (97.8 percent), anti-ds DNA antibody (82.2 percent), lupus nephritis (71.1 percent), malar rash (71.1 percent), and cytopenia (66.7 percent) were the most common findings among the classification criteria by ACR (American College of Rhematology, 1997). Conclusion : Clinical manifestations and prognosis are various in pediatric SLE. Intensive studies of SLE in children should be continued for more effective treatment.

Objective : The purpose of this study was to develop an assessment tool to measure Korean occupational balance. Methods : From March 2017 to July 2019, preliminary questionnaire was prepared through analysis of previous research and expert focus meeting, and preliminary questions were selected through the Delphi survey. In order to verify the validity of the items, Rash analysis was conducted to analyze the persons and items fitness, the distribution of item difficulty, separation reliability, and the appropriateness of the rating scale. Results : Among 141 subjects, 9 (6.38%) in time use and 11 (7.80%) in the occupation area were inappropriate subjects. As a result of analyzing the appropriateness of the items except for the inappropriate subjects, the 3 items were judged as ineligible items, but 1 item of the occupation characteristics was finally deleted based on the theoretical and clinical grounds. In the analysis of the scale, 4 points were more appropriate than the 5 point scale, and the separation reliability was .86~.94. Finally, 3 categories (time use, occupation area, occupation characteristics) and 18 items were selected. Conclusion : The occupational balance assessment tool was selected three categories and 18 questions finally, three categories and 18 questions, and was developed on a four-point Likert scale. Further research needs to prove the concurrent validity of the K-OBA and to analyze the factors that influence the occupational balance.

Purpose : To identify clinical and laboratory features of atypical Kawasaki disease(KD), and to develop criteria for early diagnosis of atypical KD patients. Methods : All patients with KD treated at our hospital from January 1998 to June 2000 were reviewed retrospectively. Results : Among a total of 167 patients, 28(16.8%) were atypical KD of which seven(25%) were infants. Among the five cardinal symptoms, oral mucosal change(96.4%) occurred most frequently, followed by conjuntivitis(57.1%) and rash(46.4%). Most notable laboratory findings were anemia, and increased erythrocyte sedementation rate(ESR) or C-reactive protein(CRP). Coronary artery abnormalities developed in seven(25.8%) atypical KD patients, compared with 14.4% in typical KD patients. We considered oral mucosal change as major criterion, and conjunctivitis, rash, hematocrit <35% and ESR >30 mm/hr or CRP >3.1 mg/dL as minor criteria. Proposed modification in diagnostic criteria for atypical KD include fever of ${\geq}5$ days＋major criterion＋${\geq}2$ minor criteria, or fever of ${\geq}5$ days＋4 minor criteria. Conclusion : The modified diagnostic criteria has yielded a sensitivity 89.3%. Our diagnostic criteria may be used for early diagnosis of atypical KD.

Most of mothers place their babies in either supine or prone position without change of position. Studies comparing supine and prone position of the newborn infants -have already been performed with the result that the prone position is relatively better than the supine position. However, one kind of position recommended to the mothers is not sufficient for the good rearing practice of children, because the same position placed for period long of time may bring out physical, mental tension and fatigue, and deformities of the skull and the thorax. For this reason nurses have to find out other position which has identical or more advantages than prone position so as to perform the position change for the babies. Main purpose of this study is to identify the differences of vital signs, the number of urination, defecation, diaper rash, crying and amount of feeding of the newborn infants with prone position or lateral position during the first three days of life. Sixty two newborn infants who were delivered at Seoul National University Hospital during the period from July 1 to September 5, 1974 were chosen as subjects for this study. The criteria for the choice of subjects were the babies born with vaginal delivery; body weight 2.5kg or over at birth; Apgar score Seven or over; and gestation period between thirty-eight months ana forty- two months. Of these subjects, by random sampling, thirty-one newborn infants were placed in the prone position and the other thirty-one in the lateral position. The results of this study reviewed in a statistical analysis of the t-test to obtain the following findings : 1. The heart rates of babies in the prone position were the mean heart rates of 135.03 and those in the lateral position 135.98 without any statistically significant difference. 2. There was no significant difference of respiration rate between two groups : a group in the prone position showed the mean respiration rates of 45,57 and the other in the lateral position 46.49. 3. There was no significant difference of body temperature between two groups: the mean body temperature of a group placed in the prone position was 98$^{\circ}$18'F(36$^{\circ}$77'C) and that of the other group 98$^{\circ}$20'F(36$^{\circ}$78'C). 4. One baby showed diaper rash only in a group of infants in the prone position. 5. The number of crying of the babies in the prone position were 23.70 and those in the lateral position 30.00 with a statistical difference at 5 percent level. 6, There was no difference of frequency of urination between two groups: the mean frequency of a group placed in tile prone position was 5.44 and that of the other group 5.06, 7. There was no significant difference of frequency of defecation between two groups : the mean frequency of a group placed in the prone position was 4.20 and that of tile other group 4.21, 8. There was no significant difference of feeding amount between two groups : the average amount of a group in the prone position showed 325.03 and that of the other group in the lateral position 291.51. All the above results mean that we may substitute tile lateral position for the Prone position or utilize both position for tile rearing practice of the babies.

Objectives : Epidermal growth factor receptor-inhibitors have demonstrated improved overall survival in patients with non-small cell lung cancer, but their use is associated with dermatologic adverse reactions that often require symptomatic treatment. Methods : A 44-year-old woman, who started the chemotherapy of Iressa$^{(R)}$ on August 2010, developed cutaneous symptoms such as papulopustular rash, dry skin, and pruritus on her face and scalp after taking Iressa$^{(R)}$ for four weeks. The patient visited our clinic with such symptoms on March 2011 and underwent herebal remedy targeted to alleviate the skin reactions. The severity of dermatologic symptoms was evaluated with the numeric rating scale and the Common Terminology Criteria for Adverse Events version 4.0. Results : Noticeable changes on the skin lesion were observed after the two months of treatment, without any dose modification of the Iressa$^{(R)}$. The cutaneous symptoms as papulopustular rash, dry skin and pruritus were improved and there was no adverse event induced by the treatment with herbal medicine. Conclusions : This case report suggests that the treatment with a herbal medicine, Samultang-gagambang be considered as a useful treatment to relieve EGFR-inhibitor induced dermatologic adverse reactions.
