본 연구는 유명 인기 캐릭터를 대상으로 한 시선추적실험을 통해 피험자의 시지각 집중도를 분석하여, 캐릭터에서 어떤 부분을 부각시키는 것이 소비자들의 관심과 호기심을 유도하는데 효과적인가를 알아보았다. 연구결과, 캐릭터의 몸보다 얼굴에 더욱 주목하였으며, 그 외 바지, 티, 신발, 수염과 같은 보조요소에도 다소 주목하는 것을 확인하였다. 이러한 결과는 캐릭터에 대한 피험자들의 시선이 자주 그리고 오래 머무는 요소가 명확하게 다름을 의미한다. 그러므로 디자이너들은 캐릭터 구성요소별 시지각 집중도의 차이를 캐릭터에 대한 사용자의 관심과 감정이입, 몰입과 같은 감성적 만족감을 느낄 수 있는 차별화 요소로 인지하고 캐릭터 디자인을 개발할 때 적극적으로 반영해야 할 것이다. 또한 각각의 보조요소의 시지각 집중도에 차이가 있었는데, 그 영향요인 또한 개인의 특성에 기인한 것인지, 아니면 또 다른 영향요인이 발현된 것인지에 대한 세심한 연구가 이루어진다면, 캐릭터 디자인의 보다 폭넓은 연구가 될 것이다.

The commercial interests in functional foods containing probiotics are gaining significance in view of increasing studies on their role in digestive tract. Probiotic dairy foods containing health-promoting bacteria are important segment of functional food market. Various health benefits have been attributed to specific strains of lactic acid bacteria or food containing these probiotic cultures. Probiotic-containing foods are considered to improve general gut health and natural defenses of body, and lower blood cholesterol level. Specific probiotic microbes can alleviate or prevent diverse intestinal diarrhea-inducing disorders, cause prophylaxis of intestinal and urogenital infections, inhibit mutagenicity of intestinal contents, and reduce incidence of intestinal tumors. Recent increasing evidences on health effects of probiotics have triggered consumer interest in this category of functional foods. Rational approach needs to be applied in selection of strains for probiotic preparation to achieve required functionality. Present article focuses on some prominent probiotic candidates and criteria for their inclusion in functional food sector.

Objectives : Motivational factor is a unique contributor to the typically poor academic performance of children with ADHD. However, few study has directly intervened learning motivation in children with ADHD. We conducted this study to explore the direct effects of the learning motivation improvement program applied to children with ADHD. Method The program was designed in order to increase an interest-inducing educational intervention, an academic skills integration, a basic learning activity (reading, writing, and math), and children's self-esteem. We conducted the program twice a week (total 10 sessions) and assessed learning motivation, teaming attitude, self-esteem, academic performance, and problem behaviors of participating children. Results : After the program, teachers reported improvement in teaming motivation. In addition, parents notified sisnificant reduction of problem behaviors. Children reported improvement in a few domains of teaming motivation and learning attitude. Conclusion : While loaming motivation is regarded as an important factor in education, there have been few studies considering this issue in both educational and psychiatric fields. The teaming motivation improvement would be needed in both field in order to reduce the deficits in academic performance in children with ADHD.

Tumor necrosis facto-related apoptosis-inducing ligand (TRAIL) is a recently identified member of the tumor necrosis factor cytokine superfamily. TRAIL has been shown to induce apoptosis in a number of tumor cells whereas cells from most of normal tissues are highly resistant to TRAIL-induced apoptosis. These observations have raised considerable interest in the use of TRAIL in tumor therapy. In this study we report the biodistribution fates and serum expression pattern of plasmid DNA encoding TRAIL (pTRAIL) delivered in erythrocyte ghosts (EG). pTRAIL was loaded into EG by electroportion in a hypotonic medium The mRNA expression of pTRAIL was prolonged following delivery in EG-encapsulated forms. EG containing pTRAIL showed significant levels of mRNA expression in the blood over 9 days. The organ expression patterns of pTRAIL delivered via EG, however, did not significantly differ from those of naked pTRAIL, indicating that the expression-enhancing effect of EG containing pTRAIL was localized to the blood. These results suggest that pTRAIL-loaded EG might be of potential use in the treatment of hematological diseases such as TRAIL-sensitive leukemia.

Mobile genetic segments, or transposons, are also referred to as jumping genes as they can shift from one position in the genome to another, thus inducing a chromosomal mutation. According to the target site-specificity of the transposon during a transposition event, the result is either the insertion of a gene of interest at a specific chromosomal site, or the creation of knockout mutants. The former situation includes the integration of conjugative transposons via site-specific recombination, several transposons preferring a target site of a conserved AT-rich sequence, and Tn7 being site-specifically inserted at attTn7, the downstream of the essential glmS gene. The latter situation is exploited for random mutagenesis in many prokaryotes, including IS (insertion sequence) elements, mariner, Mu, Tn3 derivatives (Tn4430 and Tn917), Tn5, modified Tn7, Tn10, Tn552, and Ty1, enabling a variety of genetic manipulations. Randomly inserted transposons have been previously employed for a variety of applications such as genetic footprinting, gene transcriptional and translational fusion, signature-tagged mutagenesis (STM), DNA or cDNA sequencing, transposon site hybridization (TraSH), and scanning linker mutagenesis (SLM). Therefore, transposon-mediated genetic engineering is a valuable discipline for the study of bacterial physiology and pathogenesis in living hosts.

Attention-deficit/hyperactivity disorder(ADHD) is one of the most common childhood-onset psychlatric disorders. It is distinguished by symptoms of inattention, hyperactivity, and impulsivity. ADHD may be accompanied by learning disabilities, depression, anxiety, conduct disorder, and oppositional defiant disorder. The etiology of ADHD is unknown, and the disorder may have several different causes. Individual with ADHD present in childhood and may continue to show symptoms as they enter adolescence and adult life. Public interest in ADHD has increased along with debate in the media concerning the diagnostic process and treatment strategies. The purpose of this study is oriental medical approach to ADHD. This study was progressed for oriental diagnosis and treatment for ADHD. In oriental medicine, the reason of ADHD was deficiency of the kidney, hyperactivity of the liver(腎虛肝亢), deficiency of the heart and the spleen(心脾不足), heart disturbed by phlegm and heat(痰熱擾心). The method of medical treatment was nourishing the kidney and checking exuberance of yang(滋腎潛陽), relieving mental stress and promoting wisdom(寧神益智), nourishing the heart and strengthening the spleen(養心健脾), tranquilzation(安神定志). removing heat-phlegm(淸熱化痰), inducing resuscitation and tranquilzation(開窮安神). The prescription was commonly used as Liuwei Dihuang Wan jiajian(六味地黃丸加減), Guipi Tang he Ganmai Dazao Tang jiajian(歸脾湯合甘麥大棗湯加減), Huanglian Wendan Tang jiawei(溫黃連溫膽湯加味). It should help primary care providers in their assessment of a common child health problem.

PURPOSE: This study examined the effects of posture improvement exercise using virtual reality programs on the posture and balance of patients with forward head postures. METHODS: Thirty men and women in their 20 s, who had a forward head posture, were divided randomly into a group with posture correction exercise and a group with posture correction exercise combined with virtual reality programs. The posture correction exercise was composed of squats, XCO training, and chin-tuck exercise. In contrast, exercise with virtual reality games involved the Hot Squat, Climbey, and Baskhead programs while wearing a headset. Both groups performed the exercises 15 min a day, three times per week, for four weeks. The balance ability, distance between the acromion and earlobe, and neck joint range of motion were assessed before and after the exercises. RESULTS: Both groups showed significant reductions in the distance between the acromion and the earlobe, along with significant improvements in the range of joint motion. The group that performed the virtual reality exercises showed a significant increase in the limit of stability. Both groups showed a significant decrease in the sway length. In contrast, the group given the virtual reality exercises showed a significant reduction in the sway speed while standing with their eyes closed. CONCLUSION: Exercise applying virtual reality programs can be used in clinical and home programs to correct the postures of individuals with a forward head posture because they can trigger interest in inducing active participation.
