Let C be a nonempty closed convex subset of a Banach space E and let $T_1, \cdots, T_N$ be nonexpansive mappings from C into itself (recall that a mapping $T : C \longrightarrow C$ is nonexpansive if $\left\$\mid$ Tx - Ty \right\$\mid$ \leq \left\$\mid$ x - y \right\$\mid$$ for all $x, y \in C$). We consider the fixed point problem for nonexpansive mappings : find a common fixed point, i.e., find a point in $\cap_{i=1}^N Fix(T_i)$, where $Fix(T_i) := {x \in C : x = T_i x}$ denotes the set of fixed points of $T_i$.

Background : This study was designed to determine if cervical epidural depth has any correlation with age, height, weight, ponderal index and neck clrcunference. Methods : Data was obtained from 102 patients successfully anesthetized with cervical epidural block. Patients were categorized into 4 groups: male C6-7, male C7-T1, female C6-7, female C7-T1 then statistically compared and analyzed. Results : The mean and standard deviation of epidural depth of male C6-7, male C&-T1, female C6-7, female C7-T1 groups were respectively as follows: 41.1+/-6.0, 47.1+/-5.6, 37.9+/-6.0, 46.4+/-5.6 mm. The results showed cervical epidural depth is well correlated with body weight and ponderal index; moderately correlated with neck circumference: slightly correlated with age; no correlation with height.

Bacillus subtilis에 존재하는 DEAD-box RNA helicase에 대한 유전자 상동성 검색을 통해 yqfR, yfmL, ydbR, deaD 의 4종류의 유전자를 확인하였고 이들 유전자 각각의 결손 돌연변이체를 제조하였다. 이들 돌연변이체들의 특성을 알아보기 위하여 LB 배양액을 사용하여 여러 온도에서의 생장 속도를 조사하였다. LB 배양액에서 $37^{\circ}C$의 생장 결과 ydbR 결손 균주가 다소 생장이 느려지나($T_d$=53 min) 다른(yqfR, yfmL, deaD) 결손 돌연변이체들은($T_d$=30-40 min) 결손이 없는 야생형 균주 CU1065와($T_d$=32 min) 유사하였다. 반면에 $22^{\circ}C$에서의 생장은 CU1065 ($T_d$=102 min)에 비해 yqfR ($T_d$=151 min), yfmL ($T_d$=214 min), ydbR ($T_d$=343 min) 결손 균주 순으로 생장속도가 느린 저온 민감성을 보인다. deaD의 $22^{\circ}C$에서의 생장 속도는 ($T_d$=109 min) CU1065와 ($T_d$=102 min) 매우 유사하여 저온 민감성을 보이지 않았다. 그리고 이들 유전자들의 이중, 삼중, 사중의 결손 균주들을 제조하였고, 여러 온도에서 ($42^{\circ}C$, $37^{\circ}C$, $22^{\circ}C$) LB 배양액을 사용하여 생장 속도를 측정 하였다. 다중 결손은 단일 결손보다 더 심한 저온 민감성을 보이며, 이중 결손의 경우, ydbR과 yfmL의 결손이 다른 조합의 결손보다 보다 큰 저온 민감성을 나타내었다 ($T_d$=984 min). 이러한 저온 민감성은 E. coli의 csdA 혹은 srmB 결손의 결과와 유사하며 리보솜 조립과 관련이 있는 생리적 기능으로 보인다.

This study purposes drawing changing tendency of apartment kitchen areas and character of that by figuring out type, form and per period cause of change of brand apartment kitchen areas. I adopted subject of study as the six leading construction companies considering the apartment rankings of brand and subcontract from 2001 to 2015 when brand apartment was activated(Samsung C&T corporation Raemian, Daelim Industrial Co., Ltd E-pyeonhansesang, Daewoo E&C Prugio, GS E&C XI, Posco E&C The sharp, Hyundai E&C Hillstate) and analyzed kitchen plane of $84m^2{\sim}102m^2$ housing units which were in great demand from apartment housing market. Also, I drew changing trends of kitchen areas by conducting a model house field survey. Through this study result, I will expect the utility of baseline data which is necessary for space development by figuring out kitchen culture, flows and cause of change.

A bacterial strain, designated B301^T and isolated from raw chicken meat obtained from a local market in Korea, was characterized and identified using a polyphasic taxonomic approach. Cells were gram-negative, non-motile, obligate-aerobic coccobacilli that were catalase-positive and oxidase-negative. The optimum growth conditions were 30℃, pH 7.0, and 0% NaCl in tryptic soy broth. Colonies were round, convex, smooth, and cream-colored on tryptic soy agar. Strain B301^T has a genome size of 3,102,684 bp, with 2,840 protein-coding genes and 102 RNA genes. The 16S rRNA gene analysis revealed that strain B301^T belongs to the genus Acinetobacter and shares highest sequence similarity (97.12%) with A. celticus ANC 4603^T and A. sichuanensis WCHAc060041^T. The average nucleotide identity and digital DNA-DNA hybridization values for closely related species were below the cutoff values for species delineation (95-96% and 70%, respectively). The DNA G+C content of strain B301^T was 37.0%. The major respiratory quinone was Q-9, and the cellular fatty acids were primarily summed feature 3 (C_16:1 ω6c/C_16:1 ω7c), C_16:0, and C_18:1 ω9c. The major polar lipids were phosphatidylethanolamine, diphosphatidyl-glycerol, phosphatidylglycerol, and phosphatidyl-serine. The antimicrobial resistance profile of strain B301^T revealed the absence of antibiotic-resistance genes. Susceptibility to a wide range of antimicrobials, including imipenem, minocycline, ampicillin, and tetracycline, was also observed. The results of the phenotypic, chemotaxonomic, and phylogenetic analyses indicate that strain B301^T represents a novel species of the genus Acinetobacter, for which the name Acinetobacter pullorum sp. nov. is proposed. The type strain is B301^T (=KACC 21653^T = JCM 33942^T).

본 논문에서는 전이규칙이 모두 102인 Uniform CA(Uniform Cellular Automata, UCA) $\mathbb{C}_u$와 특성다항식이 $(x+1)^m$인 m-셀 90/150 hybrid CA $\mathbb{C}_h$를 합성한 CA의 특성을 분석한다. 먼저 $\mathbb{C}_u$로부터 유도된 여원 그룹 CA의 사이클 구조를 분석하고 이를 통해 모든 사이클의 길이가 같아지는 여원 CA의 조건을 제시한다. 그리고 $\mathbb{C}_u$와 $\mathbb{C}_h$를 합성한 CA $\mathbb{C}$의 최소다항식이 $(x+1)^q$일 때 $(T+I)^{q-1}F{\neq}0$을 만족하는 F를 여원벡터로 택하여 구성한 여원 그룹 CA $\mathbb{C}^{\prime}$의 사이클 구조를 분석한다.

A series of waterbome poly(urethane-urea) anionomers were prepared from isophorone diisocyanate (IPDI), polycaprolactone diol (PCL), dimethylol propionic acid (DMPA), ethylene diamine (EDA), and triethylamine (TEA), NaOH, or Cu($(COOCH_3)_2$) as neutralizing agent. This study was performed to decide the effect of neutralizing agent type on the particle size viscosity, hydrogen bonding index, adhesive strength, antistaticity, antibacterial and mechanical properties. The particle size of the dispersions decreased in the following order: TEA based samples (T-sample), NaOH based samples (N-sample), and Cu($(COOCH_3)_2$) based sample (C-sample). The viscosity of the dispersions increased in the order of C-sample, N-sample, and T-sample. Metal salt based film samples Of and C-sample) had much higher antistaticity than TEA based sample. By infrared spectroscopy, it was found that the hydrogen bonding index (or fraction) of samples decreased in the order of T-sam-pie, N-sample, and C-sample. The adhesive strength and tensile modulus/strength decreased in the order of T-sample, N-sam-pie, and C-sample. The C-sample had strong antibacterial halo, however, T- and N-samples did not

This study was designed to investigate, in the Turkish population, the association of methylene tetrahydrofolate reductase (MTHFR) C677T polymorphism and left ventricular hypertrophy (LVH) in patients with type II diabetes mellitus. Our study included 249 patients with type II diabetes mellitus (102 men, 147 women) and 214 healthy volunteers as controls (91 men, 123 women). MTHFR C677T genotypes were determined by polymerase chain reaction, restriction fragment length polymorphism techniques. No differences were observed in the distribution of MTHFR genotypes or allele frequencies in the cases versus the controls. The frequency of the MTHFR-mutated allele (T) was 31.7% in the type II diabetes mellitus versus 31.1% of the controls. The homozygous mutation (T/T) in the MTHFR gene was identified in 12% of the type II diabetes mellitus versus 9.3% of the controls. Patients with the TT genotype showed a higher prevalence of LVH when compared to patients with the CC and CT genotypes (p = 0.01). The MTHFR gene C677T mutation may be a possible risk factor for the development of LVH in the type II diabetic patients.
