본 연구는 최근 현저하게 증가하고 있는 어린이들의 유튜브 이용량에 영향을 미치는 변인들에 대한 연구이다. 이를 위해, 유튜브 이용에 영향을 미치는 변인으로 이용방식, 조절능력, 콘텐츠 인식, 중재방식을 설정하고, 연령대별 이들 변인들을 비교하고 유튜브 이용량에 어떻게 영향을 미치는지를 분석하는 것을 목적으로 하고 있다. 연구결과, 연령대별 이용량은 차이가 없었으나 이용방식 중 구독채널 유무와 일반채널 이용, 조절능력, 콘텐츠 인식, 그리고 중재 방식 중 기술통제와 감독은 차이가 있는 것으로 나타났다. 이용량에 영향을 미치는 변인들은 3-4세 집단은 구독채널 유무와 감독이, 5-6세 집단은 구독유무, 조절능력, 일반채널, 부모감독, 대화지도의 순으로 나타났다. 7-9세 집단은 구독채널 유무, 조절능력, 프리미엄 서비스 가입으로 나타났다. 이러한 결과는 연령대별 유의미한 변인들의 유사성과 상이성을 발견함으로서 유튜브 이용량을 감소시키는 전략을 다르게 구사해야 한다는 것을 시사한다. 또한 그동안 덜 다루어진 어린이의 유튜브 이용방식에 대한 보다 구체적인 분류와 이들 방식들이 미치는 영향력에 대한 연구의 필요성을 제기하고 있다.

This study examined the risk components and risk types perceived in the context of purchasing decisions of paper fashion products. This study also identified the levels of perceived risk by consumers and the differences between age groups in risk perception. First, qualitative data were collected through a focus group interview with 7 Korean females in their 20s to 50s. The interviewees were presented with two types of paper materials (undyed and dyed Jumchi-Hanji) and products (bags and wallets) made with the papers. The interviewees mentioned 11 risk components which were classified into five types of risks: performance (easily torn/lack of durableness, lint/pilling/wear-out, lack of water-resistant, no washability, and deformation and discoloration over time), social-psychological (old and traditional image), aesthetic (lack of design diversity, unsatisfactory appearance due to repair), financial (expensive price, lack of usability in daily life) and time/convenience (difficulty in handling) risks. Based on the results of the interview, a measurement for evaluating the risk perception of paper fashion products was developed. Second, quantitative data were collected from 64 Korean women in their 20s to 50s using the measurement. Respondents who were presented with the paper materials and the products perceived the performance risk more strongly than the social-psychological risk and aesthetic risk. In addition, differences between age groups were found: younger respondents perceived performance risk and social-psychological risk more strongly than older respondents, but older respondents perceived financial risk more than younger respondents. Based on this study, strategies for the risk reduction of paper fashion products were proposed.

Purpose - This research aims to understand the different behaviors of consumers according to cognitive age. Specifically, this research is focused on pro-social behavior. Pro-social behavior is defined as behavior benefiting others, rather than behavior benefiting one's self. It often entails individual risk or cost, such as when giving resources to others, waiting in line, asking for or paying a fair price, or risking one's life in battle. Therefore, we sought to understand consumer psychology and cognitive age as a reflection of inner psychology. People frequently perceive themselves as younger or older than their chronological ages. This self-perceived or cognitive age is a subjective age perception independent of actual chronological age. The discrepancy degree between chronological and cognitive age represents how much individuals perceive themselves as younger than they are. This study examines the gap in donation intention based on cognitive age. In order to investigate cognitive age, composed of four sub-categories (feel-age, look-age, do-age, and interest-age), this study explores the differential donation intention based on cognitive age, which determines the relationship between the young age and old age. Research design, data, and methodology - Data research was conducted by gathering 216 survey samples, excluding those with unreliable answers. Data coding and cleaning were used and SPSS 19.0 software for the data analysis. The respondents were categorized into two types, younger cognitive ages and older cognitive ages. Additionally, we analyzed the moderating variables. In particular, we used cognitive age degree and congruency level (cognitive age low vs. cognitive age high) × (congruency close vs. congruency distant) between - subjects design. First, regression was done to verify the difference between chronological age and cognitive age. Second, a t-test was done to verify the difference of cognitive age level in donations. Third, ANOVA (analysis of variance) was done to verify the difference between cognitive age and congruency in donations. Last, ANOVA was done to verify the difference between cognitive age and moral judgments in donations. Result - The results show most respondents perceive themselves as younger than their chronological ages. In particular, older respondents feel they are younger than their actual age. Moreover, the result of the comparison between low degree and high degree groups of cognitive age, show high donations at the higher degree of cognitive age groups. In addition, the closer the distance to the beneficiaries, the higher the donation in high degree cognitive age groups. The higher moral judgment groups also show relatively high contributions in lower degree cognitive age groups. Conclusions - Donations belong to the category of pro-social behavior reflecting an individual's psychological state. Therefore, it is important in understanding cognitive age. This study implies that it is necessary to take into account both cognitive age and chronological age when segmenting donors. Moreover, this study confirmed that there are different factors affecting the motives behind donations. Thus, it may be utilized to create differential donation strategies.

This study investigated parents' attitude about children's unbalanced diet. The subjects were 1,309 parents that their children attended at kindergarten or child care center in Kyoung-Ki province. The order of dislikes in 'vegetables and fruits' was as follows: all kinds of vegetables (56.6%), beans (17.6%), fruits (5.2%). In 'meat, fish, poultry', the order of dislikes was meats (38.2%), fishes (21.8%), milk (16.4%), eggs (10.0%). In 'cerelas', the order of dislikes was rice (31.0%), rice cakes (14.3%), noodles (11.9%). The several rationalizations for dislikes are 'taste' (19.1 %), 'food habit from younger age' (18.4%), 'lack of chances for trying new food' (16.0%) etc. To compared children's rationalizations for dislikes to their age group, the percentage of 'lack of chances for trying new food', 'strange food shape', 'lack of nutrition education' was significantly higher in 'below 5 years old' (<5) group than other groups (<6, <7) and 'sweety food' was significantly higher in 'below 7 years old' (<7) group than other groups (<6, <7)(p <0.05). In parents' attitude about children's unbalanced dietary habit, subjects answered that they try to make children understand to eat dislike food (73.9%), develop new recipe for children (14.0%), neglect children's food habit (6.2%). To compared parents' attitude for children's unbalanced diet by parents age, the percentage of 'try to make children understand to eat dislike food' was significantly higher in 'below 30 years old' (<30) group than other groups ($30{\sim}35,\;35{\sim}39,\;{\geq}40$) and 'developing new recipe' was significantly higher in 'over 40 years old' (${\geq}40$) group than other groups ($<30,\;30{\sim}35,\;35{\sim}39$)(p < 0.05). To compared parents' attitude for children's unbalanced diet by parents' occupation, the percentage of 'neglecting' was higher in employed group and 'developing new recipe' was higher in unemployed group than the other group. According to the results of the survey, it is necessary to make new educational materials for employed parents and young children and develop new recipes to use various kind of foods instead of forcing unpleasant foods on the children for the sake of unbalanced diet.

Causal relationships of kindergarteners' phonological awareness and processing to their ability to read words was investigated with the participation of 289 4- to 6-year-old children attending three kindergartens in Busan. Results showed gradual growth in reading ability with age. Children performed best in reading words and poorest in reading low frequency letters. They showed continuous development in skills of syllable deletion, phoneme substitution, phoneme insertion, phonological memory and naming. Discontinuous development was found in counting syllables. Longer syllables were difficult to count, and middle syllables of 3 syllable words were hard to delete. Children had poor perception of final consonants of Consonant-Vowel-Consonant syllables. Children's phonological awareness and processing were latent variables strongly related to ability to read words written in Hangul.

At present, in Korea, due to developments in medicine and technology and an increasing mean lifespan, the expected lifetime for elderly people is increasing (at 70 years, the expected additional lifespan is 14.8 years for males and 18.3 years for females). However, among all causes of death, malignant neoplasm is ranked first for all ages. Further, the incidence rate of oral cancer tends to increase with age. Thus, oral and maxillofacial surgeons have increased opportunity to experience the 'oldest old' patients with oral cancer. Elderly patients commonly have several comorbidities, poor general condition, limited socioeconomic support, fear of various postoperative complications, and perception of short for the rest of their life. In this situation, the patient, caregiver, and surgeon often choose undergraded treatment rather than standard treatment for oral squamous cell carcinoma owing to patient age. In elderly patients with oral cancer, ablation of tumor or reconstructive surgery is challenging for surgeons. Oral and maxillofacial surgeons must evaluate carefully the patient's medical condition and make a decision regarding treatment plans after sufficient discussion with patient and caregivers. We review the literature to consider the factors involved for deciding on a treatment plan regarding surgery in elderly patients with oral cancer.

This study as a cross survey study was conducted to provide basic data for more practical approach to nursing the aged, by analyzing the relationship of the loneliness, self-esteem and quality of life on the hearing disturbance aged. This study was based on the survey data from the 90 aged, who are over sity years old and resident in Seoul. In order to measure the general characteristics and subjective audition, Cantril's Ladder Scale Tool was used. For the loneliness, UCLA Loneliness Scale Tool (translated into Korean to suit the Korean environment by Kim's). In order to measure the self-esteem, Rosenberg's Self-esteem Measurement Tool (translated into Korean by Chun) was used. No's Quality of Life Measurement Tool was used to the measure the quality of life. The Data were collected by direct interviewing on the subjects for this study from August 10, 1999 to September 15, 1999. In accordance with each purpose of this study, appropriate analyzing methods such as Descriptive Statistics, T-test, and ANOVA were used in analyzing the collected data. Pearson correlation coefficient was used to test the relationship of the loneliness, self-esteem and quality of life on the hearing disturbance aged. The result of this study is as follows: 1) The average of the degrees of subjective audition was 7.22, The factors that cause the result were sex, religion, the perception of health, the married state. 2) The average of the degrees of loneliness was 55.18, The factor that cause the result was the perception of health. 3) The average of the degrees of self-esteem was 28.42, The factors that cause the result were the number of family, the number of children, the perception of health. 4) The average of the degrees of quality of life was 71.87 the factors that cause the result were age, education, the number of children, the perception of health. 5) Correlation of Loneliness, self-esteem and quality of life is the perception of loneliness showed significant negative correlation with self-esteem (r=-.466, p=.0001) and quality of life (r=-.450, p=.0001). As a result of analysis above: Because of the recognition change of the aged, it seems to them that the subjective audition scale on the hearing disturbance aged is measured by only 10-point ladder scale is inappropriate. Therefore, it is necessary that the physiologic-index can confirm more exactly should be applied to them. It is very important that the social-psychological factor that has influence on the aged should be the self-perception of health. Thus, proper development of nursing intervention should be required to process in the self-perception of health on the aged.

자음의 정확도와 습득 시기에 관한 국내외 선행연구들은 상당히 많은 반면, 유아 혹은 아동의 발화를 대상으로 한 비전문가 혹은 일반 성인을 대상으로 한 지각 실험은 상당히 빈약한 편이다. 본 논문에서는 그러한 공백을 채우기 위해 2세에서 6세 사이의 아동들이 자신들에게 친숙하다고 판단되는 단음절 단어를 발화하게 하여, 이 단음절 단어를 자극으로 사용하여 일반 성인화자들을 대상으로 교차 지각 실험을 수행되었다. CVC 형태의 단음절 단어들은 2-6세 사이의 아동들의 발화에서 추출되었으며, 전체 20명으로 구성된 성인 화자들을 5 그룹으로 나누어, 아동 발화를 들리는 대로 받아 적게 하는 과업을 수행하였다. 분석을 위해서는 다음의 3가지 조건을 상정하여 분석하였다: (1) VC를 고려하지 않은 상태에서 초성 자음만 아동의 조음과 성인의 화자가 일치하는 조건, (2) 종성은 고려하지 않으면서 CV 형태만 조음과 지각이 일치하는 조건, 그리고 (3) CVC 형태인 단어 전체의 조음과 지각이 일치하는 조건. 분석 결과를 살펴보면, 단어 전체의 일치도가 가장 낮았으며, 초성만 고려했을 때의 일치도가 가장 높았다. 또한 일반적인 경향은 아동들의 나이가 많아짐에 따라 아동의 발화와 성인의 지각 반응 사이에 일치도가 높아졌다. 하지만 아동 자음의 습득 연령이 빠르면 2세부터 시작되어 5세 정도면 거의 완성된다고 보고한 전문가들의 진단과는 달리, 일반 성인 화자들은 아동의 발화에 대해서 적어도 5세 정도는 되어야 75% 정도의 일치도를 보이는 것으로 관찰되었다. 본 연구는 아동의 언어 발달 과정에서 관찰되는 일반 성인들의 지각에 대한 이해를 높이는 데 중요한 기여를 하였다. 즉 본 연구가 가지는 의의는 아동의 말소리 습득과 관련하여 전문가의 정확한 판단과 아동을 양육하는 부모 혹은 전문가가 아닌 일반 성인의 지각이 다를 수 있다는 것이다. 아동 발달 과정에서 5세 전의 아동들에게서 다소 알아듣기 힘든 단어나 자음이 관찰되더라도, 이는 말소리 지연이나 언어 장애와 관련된 현상은 아니라, 아동의 말소리에 익숙하지 않은 일반 성인이 가지는 지각의 한계일 수 있다는 점을 염두에 둘 필요가 있다.

Senescent effects are the gradual deterioration of function caused by biological aging. Senescent effects on color vision are not clearly understood even after considerable researches. Part of the reason is that the color vision is a complex phenomenon resulting from various factors such as organic systems, and the physical (neuro-optical) and the psychological (experiential) processes of color perception. We performed a field experiment on color perceptional differences due to aging vision. Our experiment was applied to two different groups in South Korea: an experimental group (46 subjects of over the age of 61 years) and a control group (49 subjects in their twenties). The experimental tools are comprised of (1) six gradual yellowing detector board (40%, 50%, 60%, 70%, 80%, 90%); (2) pairs of vivid-strong, vivid-deep, grayish-deep, deep-dull, and bright-light tones of Blue (B) and Purple (P) colors; (3) Red (R), Yellow (Y), Green (G), Blue (B), and Purple (P) colors of dull-tones and pale-tones; and (4) a questionnaire on the semantic differential scales of the color images and color differences. A diagnosis system of gradual yellow vision, developed by the authors for this study, was adapted to generate the color detecting boards. The results are as follows. (1) There are significant differences between the two groups in detecting colors that simulate 40% and 50% of yellow vision. (2) As to the color difference detecting ability between similar tones, the experimental group shows difficulties in pairs of vivid-strong tones and deep-dull tones of the B color. And (3), the emotional responses to the dull tone and the pale tone are not stable in the red, the yellow, blue, and purple. Thus, we empirically demonstrate the specific differences in color perception between the old and young groups.
