한국의 사회, 문화유산이 녹아있는 서울의 문화적 가치를 재현함에 있어 장인의 기여가 현대에 와서는 크게 부각되지 않고 있다. 우리 사회의 많은 디자인에 장인의 감각과 능력이 눈에 보이지 않게 중요한 기초가 되었다. 서울시가 주최한 상암동 평화의 공원에서 개최된 서울정원박람회에서 새로운 정원디자인의 목표에 접근하는 방법으로 장인들의 작업 속에 나타나는 전통문화의 해석과 공간적인 특성을 통해 표현하고자 하였다. 서울 장인정원 설계는 전통적인 서울문화를 장인의 개념을 통해 상징적으로 함축하여 공간적인 의미를 전달하는 것에 초점을 맞추었다. 정원에서는 사람으로서의 장인, 그들이 사용하였던 도구, 그들이 만든 공예품, 그들의 이미지를 자연으로 드러내는 4개의 장인 문화에 대한 층위개념을 설정하였다. 자연으로서 정원의 그라스와 꽃은 대비효과를 위해 큰 원형의 안과 밖에서 상호 관계 되도록 하였다. 장인의 상징적인 이미지와 자연과의 관계에서 공예품의 배경으로 그라스를 사용하고 시각적인 오브제로서 관목 파티션의 반복과 꽃을 사용하였다. 이 설계의 메타포는 강한 시각적 호기심을 끌 수 있는 독특한 해법이며 따라서 정원의 방문자에게 서울 장인 정원의 상징적인 의미를 제공하게 된다.

고분자 PVDF 중공사막과 알루미나 평관형 정밀여과막의 침지식 여과에서 Sodium Alginate 파울링 거동을 관찰하였다. 공기폭기 없이 SA농도 (0.1 g/L)와 투과플럭스 (30 L/m²/hr)에서 PVDF막의 파울링 속도가 세라믹막 보다 높았다. SA 파울링 속도는 NaCl와 CaCl2 첨가 이온강도에서 더욱 높게 관찰되었다. 공기폭기를 적용 시 SA 파울링은 감소하였으나 동일한 공기유량에서 중공사막의 경우 세라믹막에 비해 감소효과는 더욱 높았다.

송아지고기는 어린 소 즉, 송아지에서 생산되는 고기이며 국제적 기준으로 1년 미만의 소에서 생산된 고기를 통칭한다. 송아지고기는 사육방법 및 도축연령에 따라 밥빌, 대용유사양 송아지고기, 곡류사양 송아지고기 및 방목사양 송아지고기로 구분한다. 생산 및 소비량이 가장 높은 송아지 고기는 대용유사양 송아지고기로 체중 200 kg 내외, 5개월령에 도축하며 육색은 핑크색을 나타낸다. 송아지고기는 일반적인 소고기에 비해 단백질 함량이 높고 지방함량이 낮으며 불포화 지방이 다수 포함되어 있고 고기의 육질이 부드럽다. 송아지고기의 육질에 양향을 미치는 요인으로 체중, 연령, 사료조성, 사료내 철분 함량 등이 있다. 송아지고기를 생산하기 위해서는 송아지고기 생산용 대용유사료가 필요하다. 일반적으로 대용유사료내 단백질 및 지방함량이 20% 내외로 체중의 10% 이상 급여하며 조사료를 자유채식하여 스트레스를 완화하고 반추위발달을 유지하도록 한다.

This study investigated the relationship between function classification systems and the Pediatric Evaluation of Disability Inventory (PEDI) functional skills in children with cerebral palsy (CP). Two hundred and eleven children with CP participated in this study. The Korean-Gross Motor Function Classification System (K-GMFCS), Korean-Manual Ability Classification System (K-MACS), Korean-Communication Function Classification System (K-CFCS), and self-care, mobility, and social function domains of the Korean-Pediatric Evaluation of Disability Inventory (K-PEDI) functional skills were measured by physical therapists or occupational therapists. All of the function classification systems were significantly correlated with PEDI functional skills (rs=-.549 to -.826) (p<.05). Especially, K-GMFCS, K-MACS, and K-CFCS were correlated significantly with mobility, self-care, and social function, respectively. Using stepwise multiple regression analysis, we established that K-GMFCS, K-MACS, and K-CFCS were predictors of self-care skills (74.3%) and mobility skills (79.5%) of the K-PEDI (p<.05). In addition, K-CFCS and K-MACS were predictors of social function (65.9%) of the K-PEDI (p<.05). The information gathered in this study using the levels measured in the function classification systems may be useful to clinicians for estimating the PEDI functional skills in children with CP.

The purpose of this study was to examine the differentiation of proprioception, invertor and evertor muscle strength, and time to peak torque at a velocity of 300 °/sec of the ankle joint in people with or without functional ankle instability (FAI). Nineteen subjects with a history of ankle sprain participated. All subjects were divided into FAI group (n1=9, Cumberland ankle instability tool (CAIT)≤24) and a control group (n2=10) based on their CAIT scores. Isokinetic dynamometer was used to measure the sense of active joint position of the ankle at mid-range and end-range of an inversion motion and invertor as well as the evertor muscle strength and time to peak torque at 300 °/s. The FAI group showed a statistically reduction in invertor and evertor muscle strength and time to peak torque when compared to the control group (p<.05). Muscle strength and time to peak torque of the invertor and evertor, as well as the sense of active joint position at end-range were also lower in the FAI group than in the control (p<.05). Correlations between CAIT score and position sense at end-range (r=-.577) and invertor muscle strength (r=.554) were statistically significant (p<.05). Individuals with FAI showed reduction in invertor and evertor muscle strength and recruitment time as well as in proprioception of the ankle joint. Thus, proprioception and invertor and evertor muscle strength of the ankle joint at fast angular velocity may be investigated when examining and planning care for individuals with FAI.

The objective of this study is to assess a level of microbial contamination in the KTX. Investigation sites in the KTX were cabin, gateway, toilet and passenger seat. It was found that the mean concentrations of airborne bacteria and fungi were 157 CFU/m³ and 84 CFU/m³ , respectively, in all of the investigation sites of the KTX. They did not exceed the domestic standard (800 CFU/m³ ) for airborne bacteria and the guideline (150 CFU/m³ ) for airborne fungi recommended by WHO. Mean levels of bacteria and fungi distributed in passenger seat were 2.6×10⁵ cfu/m³ and 3.7×104 cfu/m³ , respectively. The predominant genera identified in the KTX were Bacillus, Corynebacterium, Staphylococcus and Micrococcus for bacteria and Aspergillus, Cladosporium and Penicillium for fungi, respectively. Based on identification result, the profiles of airborne bacteria and fungi in the KTX was wholly similar to those of bacteria and fungi distributed in the passenger seat.

The purposes of this study were to compare the reliability and validity of an 88-item version of the Gross Motor Function Measure (GMFM-88) and a 66-item version of GMFM (GMFM-66) in children with cerebral palsy (CP). The GMFM was completed in 154 children with CP (age range = 6~12). The internal consistency of the GMFM was calculated by Cronbach's for judging reliability. The reliability of GMFM-88 and GMFM-66 were both above .99. The validity of measurement obtained by the GMFM was assessed by examining the unidimensionality of items and by comparing Gross Motor Function Classification System (GMFCS) levels with tests of the GMFM. Both the GMFM-88 and GMFM-66 were satisfied with unidimensionality. Discriminant validity was demonstrated on significant decreases in scores with increasing GMFCS levels in both measurements. However, GMFM-66 was a more sensitive discriminant in GMFCS level 1 and level 2 and in level 2 and level 4. This study reported a comparison of the reliability and validity of GMFM-88 and GMFM-66. The results of this study have implications for the information on the psychometric properties of two versions of GMFCS. This information will be useful for the selection of tools in clinics.

The purposes of this study were to examine inter-rater reliability of the Manual Ability Classification System (MACS) by children's age and to identify the correlation between the MACS and the Gross Motor Function Classification System (GMFCS) in children with cerebral palsy (CP). Twenty-six children with CP older than two years participated. Children with CP were classified according to the MACS and the GMFCS by two physical therapists. Inter-rater reliability was analyzed using the Intraclass Correlation Coefficients (ICCs). The results showed that the reliability of the MACS for children aged 2~3 years was .88 and for children aged above 4 years was .98 (p<.05). Children with quadriplegia had a higher level of MACS than children with spastic hemiplegia and diplegia. A moderate relationship between the MACS and the GMFCS was found in all children (rater 1, r=.631; rater 2, r=.438). The MACS will be used for classification of children with CP according to the manual abilities. Thus, it offers a reliable method for communicating between therapists about the manual ability of children with CP who are older than 2 years.

Tantalum nitrides () have been developed to substitute the Cd based pigments for non-toxic red pigment. Various doping elements were doped to reduce the amount of high price Tantalum element used and preserve the red color tonality. Doping elements were added in the synthesizing process of precursor of amorphous tantalum oxides and then Tantalum nitrides doped with various elements were obtained by ammonolysis process. The average particle size of final nitrides with secondary phases was larger than the nitride without the secondary phases. Also secondary phases reduced the red color tonality of final products. On the other hand, final nitrides without secondary phase had orthorhombic crystal system and presented good red color. In other words, in the case of nitrides without secondary phases, doping elements made a solid solution of tantalum nitride. In this context, doping process controlled the ionic state of nitrides and the amount of oxygen/nitrogen in final nitrides affected the color tonality.

The purpose of this study was to examine the path analysis of factors related to musculoskeletal diseases of shipbuilding workers by considering related factors synthetically. The survey was completed by 1,536 shipbuilding workers and except for poor responses, 1,532 were analyzed. The survey consisted of questions about lifestyle, duration of service, physical and mental stress, and musculoskeletal diseases. The collected data was analyzed with SPSS/PC+ (a descriptive statistics program) and with AMOS 4.0 (a statistical program for path modeling) to test whether the hypothesized path model fitted the collected data. The results of the correlation analysis showed that musculoskeletal disease was associated with duration of service (r=-.095), physical stress (r=.077), and mental stress (r=.602). The results of the hypothesized path model satisfied the criteria required in relation to fitting the collected data. Musculoskeletal disease was directly affected by mental stress but not by physical stress, duration of service and life style. Thus, it is suggested that reducing mental stress is a strategy for the prevention for musculoskeletal disease.

The purpose of this study was to investigate electromyographic activities of the flexor digitorum superficialis (FDS) and the flexor carpi ulnaris (FCU) by the shape of the ultrasound head. Twelve healthy subjects participated and performed ultrasound therapy with a round head and a long handled head during each 5-minute application. Electromyographic activities of the FDS and FCU were recorded by surface electrodes and normalized by maximal voluntary isometric contraction (MVIC) values. There was no difference in the muscular fatigue of FDS and FCU as determined by the shape of the ultrasound head (p>.05). Without the shape of head, the mean power frequency decreased with the time. There also was no difference in %MVIC of the FDS and FCU as determined by the shape of the ultrasound head (p>.05), but the force exerted exceeded 20%MVIC. There was however a significant difference in the amount of cumulative workload of the FDS and FCU as determined by the shape of ultrasound head (p<.05). The workload was however not affected by the shape of the ultrasound head. Constant static grasp of ultrasound transducer head during ultrasound therapy is considered a high risk factor of work-related musculoskeletal disease.

The purpose of this study was to investigate effect of hospital-based physical and occupational therapy on Modified Barthel Index (MBI) score in stroke inpatients at least 3 months after stroke, to predict MBI score at discharge from subscales of MBI, and determine the characteristics of stroke at admission. Forty-five stroke inpatients participated and received physical and occupational therapy for two months. All participants were assessed on MBI at admission and discharge. The collected data was analyzed by dependency level (MBI≤74 and MBI≥75) at admission. The results revealed that the MBI score at discharge was significantly improved compared to the MBI score at admission in the group with more than moderate dependency level (MBI≤74). In particular, personal hygiene, dressing, ambulation, and chair/bed transfer were improved. But only ambulation was improved significantly in the group with a less than mild dependency level (MBI≥75). The chair/bed transfer, dressing, ambulation, and Mini-Mental State Exam-Korea score at admission were important factors in the MBI score at discharge. Eighty-six percent of the variation in MBI score function at discharge can be explained. Therefore, it is suggested that hospital-based physical and occupational therapy in subacute stroke improve independent living status, especially for patients with a more than moderate dependency level.

Numerical simulation using computational fluid dynamics (CFD) was performed to calculate the predicted mean vote (PMV) based on velocity and temperature profiles of air in a partitioned office building. The office building (W:14.65 m, D:7.57 m, and H:2.63 m) was divided by partitions of 1.5 m height and shared by 7 office workers. Each person uses a personal computer and printer on a desk. One stand-type air conditioner was installed in the corner of the room and operated at the variable flow rate of 35 ㎥/min. In the case study, we assumed that the initial temperature of the room was 303 K and it was cooled down by operating air-conditioner. The outside temperature was fixed at 303 K and the heat flux through the windows was included in the calculation. Heat sources of personal computers, human bodies, fluorescent lamps, and refrigerator were considered. The temperature and PMV values were also calculated to asses the thermal comfort of each person by operating time of air conditioner. It was found that the thermal comfort could be improved by changing the angle of diffuser grill of air conditioner.
