적외선 영상에서의 Point Target 검출을 위한 저역 통과 필터
김영춘,신용달,심태은 永同大學校 1999 硏究論叢 Vol.5 No.1
본 논문에서는 적외선 영상에서의 point target 검출을 위한 적응적 저역 통과 필터를 제안하였다. 제안한 방법은 적외선 영상의 통계적인 특성에 따라 필터의 계수 값을 계산한다. 그래서 균일한 특성을 가지는 영상을 얻는다. 이 영상에 대하여 point target 검출을 위하여 고정된 문턱값을 사용할 수 있다. In this paper, we propose adaptive low pass filter for point target detection in infrared images. This method calculates filter coefficients according to statistical characteristics of infrared images. Thus we obtain the image with uniform characteristics. For this image, we can use the fixed threshold value for point target detection.

This study was to examine the effect of VMD factors on brand identity for SPA brands. As brand stimulus, four SPA brands(e.g., Basic House, Codes combine, Uniqlo, Zara) were selected by pretest. For collecting data, a self-administered questionnaire was developed based on the literatures and intercept survey was conducted. A total 508 usable responses were obtained from consumers who shopped at the selected brands' stores. For data analysis, descriptive statistics, factor analysis, and regression analysis were used. As perceived by consumers, VMD consisted of seven factors: lightening, scent, color, layout, music, window display, and item presentation. The VMD factor was significantly related to brand identity for the SPA brands. Specifically, brand awareness was predicted by color, layout and item presentation; brand association strength was predicted by color, layout, and widow display; favorable brand association was predicted by item presentation; salience of brand association was predicted by color and music; and brand image association was predicted by color, layout, music, and item presentation. Thus, this study discussed a managerial implication for SPA retailers to develop a visual merchandising strategy in the competitive marketplace.

The present study investigated the relationship between the social problem solving ability of children and the language patterns of their mothers. The subjects included 193 nine yearolds (185 girls, 108 boys), and 230 twelve yearolds (115 girls, 115 boys). The instruments used were a language patterns test for the mother and IPA (Interpersonal Problem Solving Ability Test) for children. Major finding from this study were: ⑴ the correlation between the social problem solving ability of children and the language patterns of their mothers was not statistically significant, ⑵ the language patterns of the mothers were significantly different by child's sex; for boys, mother used more ordered language patterns and for girls, mothers used more ordered language patterns and for girls, mothers used more humanoriented language patterns, ⑶ the social problem solving ability of children were significantly different by child's age; 12yearolds exhibited higher ability than 9yearolds.

Purpose: A nationwide outbreak of Mycoplasma pneumoniae pneumonia (MP) refractory to macrolide antibiotics occurred in Korea during 2011. Steroid therapy has been reported to be both efficacious and well tolerated in pediatric patients with refractory MP. We compared clinical features and laboratory characteristics between children with refractory MP requiring steroid treatment and those with macrolide-responsive MP and evaluated the risk factors associated with refractory MP. Methods: We investigated 203 children who were admitted to our institution with MP from June to November 2011. Refractory MP was defined by persistent fever over $38.3^{\circ}C$ with progressive pulmonary consolidation or pleural effusion despite administration of appropriate macrolide antibiotics for 5 days or longer after admission. Steroid therapy was initiated on the fifth day after admission for refractory cases. Results: There were 26 patients with refractory MP requiring steroid therapy. The mean duration of steroid therapy was 5.4 days and most of the patients were afebrile within 24 hours after initiation of steroid therapy. The prevalence of refractory MP was higher in patients with pleural effusion, lobar pneumonia affecting more than 2 lobes, higher levels of serum lactate dehydrogenase, increased oxygen requirements, and longer duration of hospitalization. Atopic sensitization and history of asthma were also associated with refractory MP after adjusting for age and gender. Conclusion: Children with refractory MP had more severe pneumonia. Atopic sensitization and history of asthma may be risk factors for refractory MP requiring steroid therapy in Korean children.
Recent Progress of PepMoV Resistant GM Pepper

The PepMoV has been considered the most frequently detected potyvirus. When it co-infects with CMV or PMMoV, it gives severe impact to total pepper harvest in Korea. Since F1 hybrid that resistant to PepMoV has not been developed, we have developed transgenic peppers using Agrobacterium-mediated transformation with a Hc-Pro gene of the PepMoV. A large number of GM peppers were tested for resistance to the PepMoV, and after consequent self-crossing up to T4 generation, a highly tolerant pepper to PepMoV called T20 was selected. So far, BC4F1 lines have been selected by back-crossing with 4 elite lines through a breeding program. Very recently, based on molecular analysis, we have selected another event, #10-2, which is also resistant to PepMoV. Horticultural difference was investigated for both GM lines, #T20 and 10-2, and no significance was found comparing to non-GM lines.

Background: Insulin resistance is an integral feature of metabolic syndromes, including obesity, hyperglycemia, and hyperlipidemia. In this study, we evaluated whether the aloe component could reduce obesity-induced inflammation and the occurrence of metabolic disorders such as blood glucose and insulin resistance. Methods: Male C57BL/6 obese mice fed a high-fat diet for 54 days received a supplement of aloe formula (PAG, ALS, Aloe QDM, and Aloe QDM complex) or pioglitazone (PGZ) and were compared with unsupplemented controls (high-fat diet; HFD) or mice fed a regular diet (RD). RT-PCR and western blot analysis were used to quantify the expression of obesity-induced inflammation. Results: Aloe QDM lowered fasting blood glucose and plasma insulin compared with HFD. Obesity-induced inflammatory cytokine (IL-$1{\beta}$, -6, -12, TNF-${\alpha}$) and chemokine (CX3CL1, CCL5) mRNA and protein were decreased markedly, as was macrophage infiltration and hepatic triglycerides by Aloe QDM. At the same time, Aloe QDM decreased the mRNA and protein of $PPAR{\gamma}/LXR{\alpha}$ and $11{\beta}$-HSD1 both in the liver and WAT. Conclusion: Dietary aloe formula reduces obesity-induced glucose tolerance not only by suppressing inflammatory responses but also by inducing anti-inflammatory cytokines in the WAT and liver, both of which are important peripheral tissues affecting insulin resistance. The effect of Aloe QDM complex in the WAT and liver are related to its dual action on $PPAR{\gamma}$ and $11{\beta}$-HSD1 ression and its use as a nutritional intervention against T2D and obesity-related inflammation is suggested.

Allergic bronchopulmonary aspergillosis (ABPA) is a hypersensitivity lung disease due to bronchial colonization of Aspergillus fumigatus that occurs in susceptible patients with asthma or cystic fibrosis. A 10-year-old girl was referred to the Department of Pediatric Pulmonology for persistent consolidations on chest radiography. Pulmonary consolidations were observed in the right upper and left lower lobes and were not resolved with a 4-week prescription of broad-spectrum antibiotics. The patient had a history of atopic dermatitis and allergic rhinitis but no history of asthma. She had no fever but produced thick and greenish sputum. Her breathing sounds were clear. On laboratory testing, her total blood eosinophil count was $1,412/mm^3$ and total serum IgE level was 2,200 kU/L. Aspergillus was isolated in the sputum culture. The A. fumigatus-specific IgE level was 15.4 kU/L, and the Aspergillus antibody test was also positive. A chest computed tomography scan demonstrated bronchial wall thickening and consolidation without bronchiectasis. An antifungal agent was added but resulted in no improvement of pulmonary consolidations after 3 weeks. Pulmonary function test was normal. Methacholine provocation test was performed, revealing bronchial hyperreactivity ($PC_{20}=5.31mg/mL$). Although the patient had no history of asthma or bronchiectasis, ABPA-seropositivity was suspected. Oral prednisolone (1 mg/kg/day) combined with antifungal therapy was started. Pulmonary consolidations began decreasing after 1 week of treatment and completely resolved after 1 month. This is the first observed and treated case of seropositive ABPA in Korean children without previously documented asthma.
