The purpose of this research was to find differences of children's behavioral pattern between players and non players of the online game "Lineage" in on-line and off line space. As a result, social behaviors of children who play online games were less active than who don't. Based on their motive and behavior pattern in online world, four behavior patterns in online world were identified; "Single-Oriented", "Community-Oriented", "Off-Real World" and "Discriminative." Off-Real World and Discriminative players were more sociable than Single-Oriented and Community-Oriented players. And Discriminative player has more self assertive attitude than others. This study may serve as a model to understand how players will respond to the various game features and how they adopt the virtual world for their interpersonal relationships.

Histiocytic necrotizing lymphadenitis, which is also commonly referred to as Kikuchi's disease (KD), is a self-limiting disease of unknown etiology. It affects individuals of all ages, although it is usually seen in young women. However, only a few descriptions of this disease are available in the pediatric literature. KD is clinically characterized by cervical lymphadenopathy, high fever, myalgia, neutropenia and, rarely, cutaneous eruptions. Cutaneous manifestations have been reported in 16-40 percent of KD cases. The specific skin changes occurring in cases of KD have yet to be completely characterized. In most of the reported cases thus far, the lesions have been located on the face and upper extremities. In this report, we describe a case of pediatric Kikuchi's disease, occurring in a 9-year-old boy. The boy exhibited transient erythematous maculopapular skin lesions over the entirety of his body, including his lower extremities.

Herein, the case of a 5-year-old boy with cytomegalovirus-induced Menetrier's disease, with peripheral eosinophilia, presenting with abdominal pain and vomiting, followed by generalized edema, is reported. The initial laboratory findings, hypoalbuminemia and peripheral eosinophilia were noted, with no evidence of renal, hepatic, cardiac or allergic diseases. Gastrofiberscopy was performed under the suspicion of eosinophilic gastroenteritis with protein losing gastropathy. The gastrofiberscopy showed the characteristic features of giant hypertrophy of the gastric rugae, with large quantities of adherent gelatinous material on the gastric fundus and body. The histological findings revealed foveolar hyperplasia, compatible with Menetrier's disease, with massive eosinophilic infiltrations. The presence of cytomegalovirus infection was identified by serology and confirmed by urine PCR. His symptoms, gastrofiberscopic findings and peripheral eosinophilia resolved spontaneously, and he has remained well for 10 months.

A certain group of phytochemicals such as isoflavone have been proven to act as a phytoestrogen. After thorough the study of different bibliographic herbs excluding soybeans, dates, pomegranates, and other publicized plants, three different edible herbs by Korean Food Regulation were extracted for the animal study on the effect of estrogen replacement. The herbal extract(FGF271) has been orally administered into 51 weeks old partial ovariectomized rats for 5 weeks with the different dosages of 100 and 1,000 mg/kg, respectively. It was observed that 1) serum estrogen level was increased in both 100 and 1,000 mg/kg group, 2) the distension of uterus was made dose dependently and significantly different in 1,000 mg/kg group (p.0.05) from control in the gross findings, 3) the weight of uterus was increased in 1,000 mg/kg group, and 4) the action on reproductive tissues was clear in the microscopic findings in terms of hyperplasia of endometrial epithelial cell, cystic change of submucosa, dilatation of uterus (significantly increased in 1,000 kg/mg), and follicular cystic changes in ovary. As a result, FGF271 seemed to act as a phytoestrogen by inducing the change in ovary and uterus and by increasing the serum estrogen concentration.

Purpose: The development of postnatal pneumothorax and its common causes and clinical aspects were studied to promote early diagnosis and proper management. Methods: A retrospective study of neonates who were hospitalized in the neonatal intensive care unit at Soonchunhyang University Bucheon Hospital from 2001 to 2010 was performed. Term neonates were divided into a spontaneous pneumothorax group and a secondary pneumothorax group. The secondary group was divided into term and preterm groups. Results: Of 4,414 inpatients, 57 (1.3%) were diagnosed with pneumothorax. Of term newborn patients, 28 (80%) had a secondary pneumothorax, and seven (20%) had a spontaneous pneumothorax. No differences were observed for gender, birth weight, resuscitation, or duration of admission between the spontaneous and control groups. The duration of treatment with a thoracostomy (20 patients, 57%) was longer in the spontaneous group (5.4${\pm}$2.9 days vs. 2.7${\pm}$2.0 days) than that in the control group. Patients with respiratory distress syndrome (RDS) developed a pneumothorax 22.8 hours after surfactant treatment, whereas patients with transient tachypnea of the newborn (TTN), pneumonia, and meconium aspiration syndrome (MAS) developed pneumothorax after 16.6 hours. Of 50 patients with a secondary pneumothorax, 19 (38%) had RDS, 11 (22%) had MAS, 7 (14%) had TTN, and six (12%) had pneumonia. Among term newborns, 42.9% were treated only with 100% oxygen. Among preterm newborns, 72.6% and 27.3% needed a thoracostomy or ventilator care, respectively. Conclusion: A pneumothorax is likely to develop when pulmonary disease occurs in neonates. Therefore, it is important to carefully identify pneumothorax and provide appropriate treatment.

Three pesticides commonly used in perilla leaf were subjected to a field residue trial to ensure safety of terminal residues in the harvest. The residual patterns of three pesticides, which were dimethomorph, indoxacarb and procymidone were examined after applying with the recommended and double dose and their DT50 were calculated. Also degradation patterns of pesticides at storage $4^{\circ}C$ were compared to those at $20^{\circ}C$, and removal rates of pesticides by washing perilla leaf with water were measured. Biological half-lives of dimethomorph, indoxacarb and procymidone were $2.91{\sim}3.11,\;2.53{\sim}3.14\;and\;2.62{\sim}2.92$ days, respectively. During the storage period, the degradation patterns were appeared more obviously at $20^{\circ}C$ than $4^{\circ}C$. Removal rates of dimethomorph, indoxacarb and procymidone were $51.3{\sim}73.3%,\;74.1{\sim}91.3%\;and\;57.9{\sim}81.6%$by various washing methods.

This study analyzed 2019 time survey data from the National Statistical Office to examine the childcare behaviors of fathers with preschool children and their determinants, considering types of care and working/nonworking days. The main results of this study are as follows. First, paternal childcare time of nonworking days was three times more than that of working days, and the participation rate was also higher on nonworking days. Second, there was no significant difference in the amount of time spent on primary care and developmental care by fathers, whether from dual- or single-income families. Third, it seems that fathers adjust their participation in childcare between working days and nonworking days in consideration of the mother's time availability. Fourth, the variables related to childcare needs had a significant influence on paternal childcare time on both working and nonworking days. Fathers' developmental care time was not explained by the independent variables entered into the regression analysis. As a result of the study, it is necessary to reduce fathers' working hours and increase family-friendly systems to increase fathers' participation in childrearing. Fathers' perception of parental responsibility must also be changed.

Objectives : The purpose of this study is to show the differences of mental stress measured with heart rate variability (HRV) and to evaluate the effects of Aromatherapy under mental stress, according to the depression index. Methods : The volunteers were allocated into 2 groups by BDI scores. Each group is divided into 2 subgroups again. After instrumentation and 10-minutes rest period, mental stress by operation was provided for 15-minutes. HRV was recorded before and after the mental stress. Then the control groups rested for 15-minutes. The experimental groups were treated with Aromatherapy. And then HRV was recorded. Results : 1. There were no significant differences in the mean HRT and SDNN between each group. 2. LF, HF, and LF norm showed different changes in each group. 3. LF/HF ratio showed significant changes. Conclusions : These results suggest that psychic factor makes an important rule under the mental stress and the effect of Aromatherapy, and Aromatherapy is effective to recover mental stress.
