In the year 2013, Warren Buffett was named one of the most influential people of the year by TIME magazine. When people are exposed to such news, they show strong interest in who the influential people are and how those people became so successful. Likewise, people show strong attachment to other prominent figures as well. This social phenomenon indicates that people perceive well-known persona like business leaders, TV stars or sports stars etc. as human brands of intangible assets. As the role of these human brands is becoming more important, people tend to develop stronger attachment toward them. Another notable modern social phenomenon is people's pursuit of life-satisfaction and social well-being. People desire to increase their quality of life by having quality time with family and friends, and also by building attachment towards celebrities, sports stars, and so on. The main objective of this study is to examine how attachment toward human brands affects quality of life. While existing studies on human brands examined antecedents of attachment, e.g., some needs fulfillment such as A-R-C needs (autonomy, relatedness and competence needs) fulfillment, this study focuses on the outcome variables of attachment, e.g., how attachment toward human brands affects stress relief and life satisfaction through self-efficacy. Based on previous research, we divided human brands into two types: heroes and celebrities. Heroes are defined as people who have considerable and lasting importance on both societal and individual levels, and celebrities are defined as people who are well-known but have little or no short-term impact on society and individual levels. This study focuses on how attachment toward each type of human brands, celebrities and heroes, affects the quality of life or well-being. This study focuses on three important outcome variables; stress relief, life satisfaction, and self-efficacy, (three variables) which have been recently gaining importance, especially in the domain of positive psychology. Major findings from the present study show that although celebrities draw attachment from people by providing fun and entertainment or providing stress relief, they have weak influences on the wellbeing or efficacy of individuals at a deeper level. In contrast, attachment toward heroes helps people live better by providing meaning and positively influencing life satisfaction through self-efficacy (Frankl 1997). These results are consistent with the main tenet of 'positive psychology' which seeks "to find and nurture genius and talent and to make normal life more fulfilling" (Seligman and Csikszentmihalyi 2000). Considering the fact that certain celebrities are perceived as heroes to some, we can conclude that celebrities can become heroes if they provide meaning and value to the lives of people. This study contributes to the research stream of human brands since the most current leading research (e.g., Thomson 2006) indicated the need to look at the resulting effect of attachment on life satisfaction through self-efficacy. Another important contribution is that we empirically documented the different effects of celebrities and heroes. As expected, this study shows that heroes more deeply influence the lives of individuals in the long term while celebrities do so rather shallowly in the short term. The issues of the influence of heroes on the individuals' lives need to be further investigated in relation with the perspective of positive psychology.

This paper presents the results of model tests for the attachment process of lightning leader to ground which is one of poorly understood processes of cloud-to-ground lightning discharges. In order to simulate the attachment process of lightning leader to ground, we investigated the discharge characteristics of air gap between the tip of needle-shaped electrode and the soil surface as a parameter of moisture content in soils when the positive and negative $1.2/50{\mu}s$ lightning impulse voltages are applied. The breakdown voltage and the discharge light were observed. As a result, the attachment processes of lightning leader to ground are strongly dependent on the grain size and the moisture content of soils. The time to breakdown was shortened with increasing the magnitude of incident impulse voltages. The delay time from application of the highest voltage to breakdown in sand is shortened with increasing the moisture content. The delay time from application of the voltage to breakdown in gravel varied from about $0.5{\mu}s$ to several ${\mu}s$. As the moisture content in soil increases, the breakdown voltages are decreased and the breakdown voltage versus time to breakdown curves are shifted toward the lower side. The results obtained in this work are similar to those for non-uniform air gap stressed by lightning impulse voltages.

The purpose of this study is to examine the effects of early full-time nonparental care during infancy/toddlerhood on children's socioemotional behaviors during the preschool period. Subjects for this study were 105 three- to five-year-olds from middle-class families in the U. S. A. Children were assigned to one of three groups according to their early care history. Children's social interactions with peers and caregivers during indoor free-play sessions in day care centers were observed for 20 minutes. The head teachers rated the children's social and emotional behaviors on two questionnaires. Mothers completed the Attachment Q-sort for attachment assessment for the preschoolers. In addition, mothers were asked to fill out a questionnaire on their parenting practices. Children who had received full-time nonparental care during infancy and/or toddlerhood were rated by their teachers as being more intellectually competent than children who did not receive full-time nonparental care during first three years of life. They were, however, rated by teachers and were observed by the researcher as being more aggressive than children with no full-time nonparental care. These children were observed to engage in less wandering/onlooking behaviors than children who had not had any full-time nonparental care. Children's attachment security scores and dependency scores did not differ as a function of early nonparental care histories. When the effects of early care patterns, sex of child, and current attachment security to mothers on aggressive behaviors of the preschoolers were examined by a hierarchical regression model, then any "pure" effects of nonparental care and of attachment security on child aggression were minimal after controlling for family background, child care center quality, and maternal childrearing practices. Strong buffering factors for the preschool children (family characteristics, parenting styles, and high quality nonparental care) mediated a possible risk factor of early nonparental care and promoted optimal outcomes for the children.

The purpose of this study is to investigate the reasons of Object Attachment Occurrence in infant and the meanings of it in his early development. For this purpose, the following hypotheses were supposed. 1. Infant's object Attachment will be a substitutional for mother attachment when he has opportunities to his mother during his first years. 2. Infant's Object Attachment will not impede the infant's normal development. In order to test this hypotheses 28 mothers whose infants show or have shown this phenomenon and 28 mothers whose infants show or have shown this phenomenon and 28 mothers whose infants do not show this one were interviewed about their child rearing practice and attitude. They were selected by the random sampling method from 310 household wives living at a delux Apt. in Seoul. The results obtained in this study are as follow ; 1. The less opportunities infant has for 1) his mother's breast feeding 2) having physical contact with his mother 3) spending time with his mother 4) receiving prompt response from his mother to his crying, the more he is apt to show this phenomenon. And infant whose first main attachment figure is not his mother also shows the same apt. 2. There was no difference between two groups in intelligence and personality. So it can be concluded that infant's Object Attachment is a substitutional phenomenon for mother attachment in the mother during his first years, and it does not impede infant's normal development.

One hundred two high-risk women(HRW) and 115 low-risk women(LRW) were studied at post-partal hospitalization and at 1, 4, and 8 months after giving birth to determine whether they would differ in the achievement of perceived maternal acquisition and whether predictors of maternal acquisition would differ for the two groups over time. The subjects were 102 HRW and 115 LRW, all in the above 27 weeks, admitted to two hospitals and to two clinic in the Kyoungnam area between July 1, 1998 and May 4, 1999. The data were analyzed by a SPSS program and the results are as follows ; 1) Predictors of Maternal role acquisition in the HRW were fetal attachment, maternal attachment, state anxiety, relationships of partner, social support in the early postpartum, maternal attachment, relationships of partner, depression, infant's health status in the postpartal 1 month, relationships of partner, self-esteem, educational degree in the postpartal 4 month, and maternal attachment, social supports in the postpartal 8 month. 2) Predictors of Maternal role acquisition in the LRW were fetal attachment, social supports, perceived experience about labor and delivery in the early postpartum, maternal attachment, sense of mastery in the postpartal 1 month, sense of mastery, experience with infants, relationships of partner in the postpartal 4 month and maternal attachment, experience with infants, social supports in the postpartal 8 month. 3) The hypothesis that HRW would score significantly lower on maternal competency than LRW was rejected. 4) The hypothesis that maternal acquisition would be significantly related to maternal attachment was accepted.

The purpose of this study was the development of teat-cup attachment module for robot milking system. The teat-cups attachment module was controlled on the two dimensional space independently, Each teat cup of an end effector was independently controlled via two axis control based on the position information data obtained from the image processing system. This system was developed install of all 4 teat cups at the same time after adjusting positions of each teat sequentially. The individual motion system was operated using two servo motors for the high speed of teat position adjustment. The errors fur the individual motion system of teat cups were maximum 1.0mm, minimum 0.0mm, and average 0.6mm. The operating time for adjusting the teat cups position required about 1.0 second. It is envisaged that teat cups attachment module can be applicate to milking robot being developed in consideration of the experiment results for the teat cups operation accuracy and the actuation speed of servo motors.

Excavators are construction machines used for digging soil, transporting soil, dismantling buildings and clearing the ground at construction sites. There are various attachments attached to the arm end of the excavator and used for various operations. There are the most common types of buckets attached for excavation and other types of attachments used for foresting, road cleaning, snow removal, and waste disposal. When multiple types of work are done at the same time, several attachments must be replaced and a device called a quick coupler is used to reduce replacement time. Although a quick coupler reduces the replacement time of the Attachment, it is necessary to attach safety devices to prevent unintentional detachment of attached attachments during the operation. To prevent the attachment from leaving or falling regardless of the operator's intention, support is installed in the hook of the bucket pin and controlled through a separate hydraulic cylinder to ensure safety. When attaching an attachment, it shall be attached without any action. This study is intended to verify the design validity of safety devices to prevent falls of attachments occurring at construction sites.

This paper discussed effect of the surface roughness and the hydrophobicity of support material on the microbial attachment In a rotating biological contactor. The by- drophoblclty of each support material was determined by the measurement of contact angle of water and the surface roughness was measured by the surface roughness In- strument. Microorganisms have well attached on the surface of more hydrophilic support material like Nylon6 than that of the hydrophobic support material like PE. When the relatively hydrophilic surface was roughen, the microbial attachment was increased but when the relatively hydrophobic surface was roughen, the attachment was slightly In- creased because the hydrophobicity of support material was Increased by roughening the hydrophobic surface. Although both variables, the surface hydrophobicity and the surface roughness, have Influenced the microbial attachment, the influence of the surface roughness overruled that of the surface hydrophobicity. Support material whose surfaces were roughened about 1mm, 6mm and 11mm were allowed for attached 3, 7 and 24hr, but the differences of maximum and minimum attachment of each material gave nearly constant values and similar trend with time.

Purpose: The main purpose of this study was to establish a nursing intervention data base to improve maternal attachment. Method: The first group of mothers( control group), experienced their first physical contact with their infants after being discharged from the hospital. The second group (experimental group) practiced early initial mother-infant postpartum contact known as the most sensitive period for founding maternal-infancy attachment. The subjects of this study gave birth to normal infants at M hospital from Aug.25 to Sept.30, 2004. During the same time, data was collected through direct observation, with instruments designed by Cropley et al., to assess the behaviors of normal attachment. The statistical methods for data analysis were percentage, mean, standard deviation and t-test with an SPSS program. Result: The group practicing initial mother-infant contact, showed a higher degree of physical and functional bonding than the group experiencing the first contact after discharge from the :10spital (control group)(p<.0l). The group practicing initial mother-infant contact, showed higher degrees of bonding attachment assessments than the group experiencing their first initial contact after their discharge from the hospital(p<.01). Conclusion: The group practicing early mother-infant contact, showed more maternal-infant interaction than the group experiencing their initial contact after their discharge from the hospital. These results show that maternal attachment behavior increases according with an early initial mother-infant contact.

This study examined the effects of self-differentiation and psychological discomfort on antenatal attachment of pregnant couples in their third trimester of pregnancy. The subjects were 182 couples in J province who had participated in the first wave of the Korea Attachment Longitudinal Study (KALS). Data were analyzed by means of frequency, percentages, Pearson's correlations, and stepwise multiple regression models using SPSS 20.0. The findings were as follows. First, the independent t-test showed that the mean scores of pregnant women's self-differentiation were lower than their spouses in all subscales except emotional cutoff, and higher than in all psychological discomfort subscales. There was no significant difference in antenatal attachment quality between women and men, but the pregnant women significantly spent more time thinking about the fetus than their spouses. Second, the stepwise multiple regression models revealed that pregnant women's emotional cutoff in self-differentiation influenced the most on both quality and quantity of antenatal attachment. Among subscales of their spouses' self-differentiation, only emotional reactivity had an impact on quality of antenatal attachment, and fusion with others had the most impact on quantity of antenatal attachment. Among the pregnant women's and their spouses' psychological discomfort subscales, only depression influenced each quality and quantity of antenatal attachment. This is the very first and only study in which the impact of the pregnant couples' self-differentiation on antenatal attachment has been examined.
