In response to the need of developing children's wear design using traditional elements, this study purposed to develop fashion designs emphasizing contemporary images based on the symbolism and formativeness of traditional dresses. For this study, we reviewed the definitions and symbolism of traditional colors and traditional patterns using previous research, and classified them according to formative shape. In addition, this study made three pieces of dress and developed unique designs by applying the traditional patterns and elements of Korean traditional dress styles. The research methods were as follows. First, we examined the images of Korean traditional colors and classified the symbols and meanings of the colors. Second, we identified the types of patterns, and classified them into shapes and symbols. Third, we designed and made actual works by applying traditional patterns. Based on the theoretical studies as presented above, we developed contemporary casual hanbok designs for children by applying symbolic and formative traditional patterns and using DTP (digital textile printing).

한경희,이성하,이현경,최현진,이범희,조희연,정해일,최용,하일수,Han, Kyoung-Hee,Lee, Sung-Ha,Lee, Hyun-Kyung,Choi, Hyun-Jin,Lee, Bum-Hee,Cho, Hee-Yeon,Cheong, Hae-Il,Choi, Yong,Ha, Il-Soo 대한소아신장학회 2007 Childhood kidney diseases Vol.11 No.2

목 적 : 소아에서 진행하는 신기능 저하는 그들의 인생에 일생 동안 심각한 영향을 준다. 소아 만성 신질환의 치료에 있어서 궁극적인 목표는 생명을 연장시키는 것뿐 아니라 만성 신질환에 이환됨으로써 발생하는 여러 합병증을 예방하고 성장과 발달을 향상시키는 것이다. 저자들은 소아 만성 신질환에서 신기능 감소와 관련된 위험요인을 분석하고자 한다. 방 법 : 1999년 8월부터 2007년 3월까지 만성 신질환에서 2기에서 4기에 해당하는 환자들의 임상적 특성을 후향적으로 조사하였다. 추정 사구체여과율은 혈중 크레아티닌과 키를 이용하여 Schwartz 공식으로 계산하였다. 연간 eGFR변화는 연구시작시의 eGFR과 마지막 추적 관찰시의 eGFR간의 차이를 추적 관찰 기간으로 나누어 계산하였다. 환자들을 추적 관찰중에 측정한 혈청 칼슘과 무기인과 함께 연령과 성별 및 원인 신질환도 연간 eGFR 변화와의 관련성을 조사하였다. 결 과 : 전체 환자는 61명이었고 이중 남자는 44명, 여자는 17명이었다. 연구 시작 시 환자들의 연령은 $7.1{\pm}4.7$세이었다. 전체 환자들의 연간 eGFR 변화는 $-1.2{\pm}11.9 mL/min/1.73m^2/year$이었다. 나이가 많거나(P=0.012), 저칼슘혈증이 있을 때(P=0.012), 고인산혈증인 경우(P=0.002) 신기능 감소와 유의한 관련이 있었다. 결 론 : 나이가 많거나, 저칼슘혈증과 고인산혈증은 소아 만성 신질환의 더 빠른 진행과 연관성이 있다. Purpose : The progressive deterioration of renal function in children can impose a serious and lifelong impact on their lives. The ultimate goal in the management of children with chronic kidney disease(CKD) is to prolong survival, to prevent complications, and to promote growth and neurodevelopment. The aim of this study is to investigate the risk factors for the decline of renal function in pediatric CKD patients. Methods : Data from patients who met the criteria for the Kidney Disease Outcomes Quality Initiative(K/DOQI) CKD stage 2 to 4 between August 1999 and March 2007 were retrospectively analyzed. The estimated glomerular filtration rate(eGFR) was calculated by the Schwartz formula, using serum creatinine levels and height. We calculated the annual eGFR change from the difference between the baseline eGFR and the last eGFR divided by the duration(years) of the follow-up period. We analyzed the association between the annual eGFR change and factors such as age, gender, K/DOQI stage, underlying renal disease, serum calcium, and inorganic phosphorous during the follow-up period. Results : Sixty one children(44 boys & 17 girls) were enrolled. The age at entry was $7.1{\pm}4.7$ years. The annual eGFR change was $-1.2{\pm}11.9 mL/min/1.73m^2/year$. Our study showed that older age(P=0.005). hypocalcemia(P=0.012), and hypenhosphatemia(P=0.002) were significantly related to more rapid decline in renal function. Conclusion : In pediatric CKD, older age, hypocalcemia and hyperphosphatemia are related to more rapid deterioration of renal function.

($Nanogide-C^{(R)}$와 $Biomesh^{(R)}$를 이용한 이개부 결손부에 대한 조직유도재생술의 임상효과

This study was designed to compare the effects of treatment using chitosan membrane $(Nanogide-C^{(R)})$ resorbable barrier with control treated by polylactic acid/polylacticglycolic acid membrane(PLA/PLGA membrane, $Biomesh^{(R)}$). 44 furcation defecs from 44 patients with class 2 furcation degree were used for this study, 22 sites of them were treated by chitosan membrane as experimental group and 22 site were treated by PLA/PLGA membrane as control group. Clinical parameters including probing depth, gingival recession, attachment level and radiographic examination were evlauated at base line, 1 month, 2 month and 3 month. after surgery. Statistical test used to analyze these data included paired t-test, one way ANOVA. The results are as follows : 1. Probing depth was significanlly decreased in the two group and there were significant differences between groups(p<0.05). 2. Gingival recession was not significanlly increased in the two group and there were no significant differences between groups(p<0.05). 3. Loss of attachment was statistically decreased in the two group and there were no significant differences between groups(p<0.05). 4. Horizontal bone level was significanlly increased in the two group and there were significant differences between groups(p<0.05). On the basis of these results, chitoans resorbable membrane has similar potential to PLA/PLGA membrane in GTR for furcation defect.

이륜자동차 창닦이기장치 등의 국내안전기준 개발

Two-wheeled motorcycles rarely use windscreen wipers in general. However, if two or more wheeled motorcycles with upper body employ windscreen wiper systems, clear visibility should be ensured regardless of weather conditions. The windscreen wiper systems include washers, defrosting, and demisting. As demands for the personal mobility are rapidly increased, the related global safety standards for motorcycles with upper body have been revised accordingly. Currently only EU regulations issue the provisions of windscreen wiper systems for L-category vehicles, which characterize two or more wheeled motorcycles. Therefore, in order to agree with international safety standards, it is necessary to revise KMVSS (Korea Motor Vehicle Safety Standards) for motorcycles. Here, KMVSS regarding windscreen wiper systems for motorcycles are studied considering the EU regulations. It is expected that the findings in this study are useful for future amendment of KMVSS.

In this study, the compressibility of resin was considered in filling analysis to account for the possible packing type flow. A numerical simulation program employing a hybrid finite element/finite difference scheme was developed to solve Hele-Shaw flow of the compressible viscous fluid at non-isothermal conditions. To advance the melt front, a control volume approach was adopted. Thin complex 3-D shapes of cavities, runners, and sprues were discretized by employing triangular, cylindrical and/or rectangular strip elements. Mass conservation was applied to each control volume to solve for the pressure distribution. Directly applying a constant mass flow rate at the inlet removes calculation of the apparent pressure boundary conditions, resulting in better simulation condition. The Cross model was used to model viscosity and the Tait equation was employed to represent density as a function of temperature and pressure. The validity of the developed program was verified through comparisons with available data in the literature and the effect of compressibility on the pressure distribution was discussed. To reduce computation time, 1-D and 2-D elements were used instead of applying triangular elements and the numerical results were compared to each other.

This study analyzes the public lecture conducted by a university in Seoul and examined how a public lecture on the emergence of a new media environment could influence the actual field of engineering education. The current public lecture is changing away from past patterns which have been conducted on a daily, irregular and offline basis. Online lectures such as Mooc programs, as well as broadcast programs in the Internet media environment, are becoming increasingly popular with mainstream education. This study focuses on exploring how public lecture experiences of engineering professors have affected the improvement of learner centered education and their communication skills. It also examines how public lecture in the field can affect to enhance public understanding of engineering. The advent of a new media environment is likely to inject new vitality into a college lecture that seems to fall behind in the past. It is highly likely that the reliance on the teaching capabilities of professors become higher according to the emphasis on active learning environment. The genre of public lecture is expected to greatly helpful to expand future engineering education methodologies.
