We report a case of an 18-month-old girl with glycogen storage disease type Ib (GSD Ib). Her neutrophil counts had gradually decreased to less than $500/{\mu}L$ by the age of 3 years. However, there were no recurrent bacterial infections. Mutation analysis of the glucose-6-phosphate translocase (G6PT) gene revealed a compound heterozygous missense mutation (Ala148Val/Gly273Asp).

Pregnancies of unmarried women are one of the most serious sex problems because they can negatively affect the lives and development of both unwed mothers and their extramarital children. The number of unwed adolescent mothers is growing recently, extending the seriousness of the problem. This study was conducted to explore the ego-state, life position and family systems that may cause unmarried pregnancy. The data obtained from the structured questionnaire survey of 79 unmarried adolescent mothers and 82 female adolescents were analyzed in terms of frequency and t-test using the SPSS WIN 8.0 program. The results were as follows: 1. Ego-state elements of unmarried adolescent mothers were distributed evenly in general and this falls under the All B(BBBBB) type of ego-gram, just like the adolescents. As for the subject adolescent mothers, CP was the lowest among the 5 egos. 2. As to the life position, the position of "I′m OK, You′re OK"was the highest for both groups, with slight differences. 3. With regard to the family system types sorted by the combination of family cohesion and family adaptability levels, both the adolescent. mothers and adolescents tended to perceive their families as somewhat-balanced or balanced families. 4. While the two groups of adolescent mothers and adolescents showed, on the whole, the same types for all the indicators like above, statistically significant differences were found in more detailed elements.

우리나라는 노령화사회로 진행되어 감에 따라 노인성 만성질환이 증가하는 추세이다. 특히 노인성 만성질환 중 전립선비대증 질환의 경우 지속적인 관리가 필요한 질환이다. 전립성비대중의 경우 생명에 큰 지장이 없으면서 주기적으로 자주 의사를 찾아야 하는 번거로움이 있고, 또한 진단 및 투약결정이 상대적으로 복잡하지 않은 질환이다. 이 논문에서는 모바일 단말기를 이용하여 환자가 자신의 관찰데이터를 병원에 전송하도록 하고, 병원의 환자관리시스템에서 분석을 통해 환자를 모니터링하면서 의사의 직접진찰 시기를 조정할 수 있도록 설계된 전립선만성질환 환자에 대한 관리시스템에 대해서 소개한다.

The purpose of this study was to examine the mediating effects of depression in the relationships between marital conflict and parenting behavior of fathers. The data from fathers of 1703 4-year-old children participating in the Panel Study of Korean Children was analyzed. Findings of this study from structural equation modeling analysis indicated that marital conflict was associated positively with depression. Parenting behavior was predicted by depression. Marital conflict had a negative effect on parenting behavior. This study showed that the relationships between marital conflict and parenting behavior were mediated by depression.

The objective of this study is to provide the guide for producing data for effective analysis of weapons systems and munitions. Therefore, the prototype from the study of creating the effectiveness data of surface to surface Artillery system under different battle environments was developed in this paper. For this purpose, mathmatical method which is in use of calculating Lethal Area and EFC(Expected Fractional Casualty) is analyzed and applied to the prototype for generating effectiveness data of surface to surface Artillery system. To validate the suggested prototype, we did the following actions: we select the source data corresponding to JMEM(Joint Munition Effectiveness Manuals) data and apply our prototype to the source data, and then match the results to check validity.

Objectives : This study was designed to evaluate the relationship with abdominal visceral fat area in obese patients identified as phlegm type. Methods : This research were performed in 201 cases, visited Kirin Oriental Hospital from March 2005 to February 2006 for weight loss. We measured body mass index(BMI), abdominal CT, and classified all patients into two groups, normal and obesity group. And then we differentiated patients with phlegm-retention symptom from patients without it through questionnaire made by Korea Institute of Oriental Medicine. Results and Conclusions : Phlegm type was significantly higher than them of no symptom of phlegm in the abdominal visceral areas(P=0.036) and ratio(P=0.007), in obesity group$(BMI{\geq}25)$. On the other hand, there is little difference between abdominal visceral fat areas of phlegm type and no symptom of phlegm in normal group. According to the above results, if obese patients are diagnosed as identification of phlegm type there is good chance of abdominal visceral obesity.

In this study, a mini hydro cyclone was designed and manufactured to achieve an inlet flow rate of 2 L/min in the experiment, which was conducted using alumina powder with a specific gravity of 3.97. This hydro cyclone was studied for using in steam and water analysis system (SWAS) of thermal power plant and was manufactured by 3D printing. Numerical analysis was performed with Solidworks Flow Simulation, utilizing the reynolds stress method (RSM) of fluid multiphase flow analysis models. Experimental and numerical analysis were performed under the three conditions of inlet velocity 2.0, 4.0, and 6.0 m/s. The separation efficiency was over 80% at all inlet velocity conditions. At the inlet velocity 4m/s, the separation efficiency was the best, and it was confirmed that the efficiency was more than 90%.

A cyclone is a dust-separating mechanism that works on the principle of centrifugal force. The performance of a cyclone is evaluated using pressure loss and collection efficiency. A multi-cyclone arrangement is used to improve the collection efficiency within a limited area. In this study, experiments and numerical analyses were conducted on a dual arrangement of mini-hydrocyclone separators, which was fabricated using 3D printing. The experiment was performed at an inlet flow rate of 0.7 m/s, and alumina powder with a particle size of 0.5, 15, and 50 ㎛. ANSYS FLUENT, was used for the numerical analysis. The reliability of the numerical analysis was verified through a comparison with the experimental results. The errors in the experiment and numerical analysis were confirmed to be 2% at the outlet flow rate.
