Objective: The purpose of this study was to gain an understanding of parenthood of mothers of early school-age children, with emphasis on cognitive, behavioral, and emotional aspects of parenthood. Methods: Nineteen mothers whose children were 1st and 2nd grade elementary school children participated in this study. Data were collected through individual in-depth interviews. During the interview, mothers were asked to speak freely about their experiences as parents of early-school age children, including parenting beliefs, parenting behaviors, and emotional experiences related to parenting. These interviews were transcribed verbatim and analyzed in a thematic way using MAXQDA. Results: Using qualitative methods, five major themes were emerged: (1) Recognizing the role of parents as a supporter of growth; (2) recognizing parenthood of the present generation that imposes expanded roles to mothers; (3) co-parenting of early school-age children and marital relationship; (4) co-existence of different parenting styles based on specific mother-child interaction situations; (5) experiencing a wide spectrum of emotions including anxiety, guilt, and depression, as well as happiness. Conclusion: This study revealed the unique cognitive, behavioral, and emotional aspects of parenthood experienced by mothers with early school-age children. Results of this study can fill a gap in our understanding of parenthood of mothers when their children entered into the new developmental stage of middle childhood. The results could also be used as a basis for developing parent education and family relationship programs.

Micron size Co-alloy(T800) powder was coated on Inconel 718 by HVOF thermal spraying for the studies of the improvement of durability of high speed spindle by using Taguchi program for the parameters of spray distance, flow rates of hydrogen and oxygen and powder feed rate. The optimal coating process was determined by the studies of coating properties such as micro-structure, porosity, surface roughness and micro hardness. Friction and wear behaviors of coatings were investigated by sliding wear test at room temperature and $1000^{\circ}F(538^{\circ}C)$. At both room temperature and $538^{\circ}C$ the sliding wear debris and friction coefficients of the coating were drastically reduced compared with the surface of non-coated parent material. This shows that Co-alloy powder coating is highly recommendable for the durability improvement surface coating of high speed air-bearing spindle. At high temperature wear traces and friction coefficients of both coating and non-coating were drastically reduced compared with those of room temperature since the brittle oxides were formed easily on the surface, and the brittle oxide phases were attrited by the reciprocating sliding wear according to the complicated mixed wear mechanisms These oxide particles, partially melts and the melts play role as lubricant and reduce the wear and friction coefficient. This also shows that Co-alloy powder coating is highly recommendable far the durability improvement surface coating on the surface vulnerable to frictional heat such as high speed spindles.

This study analysed marital comflicts, related factors, and adjustments to those conflicts described by urban Korean women. The purpose was to discover directions for resolution that would enhance the helpfulness of volunteers or prfessionals working with women in counselling settings. The investigator interviewed 20 married women, all mothers and housewives living in Seoul, attending marriage encounter programs and the Lifeline telephone counselling service. An interview schedule using six open-ended questiona guided the data colleciton which took place between May 31 and December 29, 1988. Content analysis of the data revealed, in order of reported frequency, the following areas of conflict: relationships between husband wife, relationships with children, relationships between the wife and her mother-in-Law, unsatisfied sexual needs, the husband's extra marital relationships, lack of self actualization and finacial matters. Analysis of the data suggested the following factors were related to the conflicts: reasons for marriage, traditional views about marriage and divorce including to accept a marriage arranged by the parents, the husband's traditonal attitude toward the sex role of the wife, the husband's patriarchical authoritarianism, and his attitude toward the wife;s empolyment outside the home. The women thought these conflicts severely affected their relationships within the famaily, particularly with their children. Literature suggests links with such poor parent-child-family relationships and adolescent or young people's social problems. Volunteers or professionals working with married women in counselling situation need to be conscious of the possibility of these conflict during assessment, and direct their guidance toward such conflict resolution. The researcher makes several suggestions which include the need for the husband to give emotional supports to his wife, to recognize the worth of housework, to share the work of the home, to fine ways to enhance the wife's self-actualization and to ease dreary housework routines by prviding modern appliances.

The aim of this study is to analyze the functional ego state of public librarians who should take a role of an information intermediary for children and young adults through the ego-gram which is suggested in transactional analysis theory and review their limit and feasibility as instructors. As a result of analysis, the whole ego state type of public librarians is founded to be N-type(Nightingale type) like NP-AC-A-CP-FC. The characteristics of this type can be interpreted as 'to show the tendency of self-denial in spite of their dedication.' So, the public librarians have to do their best to develop A(Adult), CP(Critical Parent) and FC(Free Child) ego state to take the requirements and behaviors of children and young adults in nurturing attitudes and enhance their autonomy and creativity through active mutual interaction. Improving A and FC is also very helpful to decrease their stress and raise their job satisfaction.

The purpose of this study is to find the correlation between authoritative parenting attitudes, emotional bonding of adolescents with parents, impulsiveness and cellular phone addiction. The paper will also explore the mediating role of impulsiveness between adolescents' emotional bonding with parents, authoritative parenting attitudes and cellular phone addiction. The subjects were made up of 237 adolescents. The data were analyzed with frequency, ANOVA, Pearson's correlation and structural equation modeling by PASW and AMOS. The instruments used were Lee et al. (1997) Parenting Attitude, Hudson (1982) Child's Attitude Toward Parent (CATP), Lee (2001) BIS (Barnett Impulsiveness Scale) and Lee (2008) Cellular Phone Addiction. The major findings were as follows: the sex of the adolescents was significantly different with cellular phone addiction and their family economic status was significantly different with adolescents' emotional bonding with parents and cellular phone addiction. Authoritative parenting attitude was negatively correlated with adolescents' emotional bonding with parents and positively correlated with impulsiveness and cellular phone addiction. Emotional bonding of adolescents with parents was negatively correlated with impulsiveness and cellular phone addiction. Adolescents' emotional bonding with parents influenced impulsiveness and cellular phone addiction negatively, and impulsiveness mediated the effects of adolescents' emotional bonding with parents, authoritative parenting attitude and cellular phone addiction. Authoritative parenting attitude influenced adolescents' impulsiveness and cellular phone addiction positively, but impulsiveness influenced cellular phone addiction positively. In conclusion, it is important to intervene in adolescents' cellular phone addiction through special education programs and counseling to build adolescents' emotional bonding with parents and to reduce impulsiveness.

Research on children should be perferably made in reference with the past thinking if it is to be affirmed by the present and to predict the future. In this respect, Buddhism, which is one of the major original thinkings in the Orient as well as the most influential religion upon Koreans daily lives and attitudes, deserves to be researched in the light of education of children. In this thesis, I have made a trial to delve into the original Buddhistic scriptures to find out Buddha's outlook on home children and arrived at the following conclusions: 1. Concerning human development stages, Buddha regarded the starting point of human life from fertilization instead of birth, even at that ancient time, and the fetal life was devided into 4, 5, or 8 stages. 2. In spite of the numerous scriptures by Buddha, very little is written about children, and even these teaching did not regard the child as an independent entity. In addition, since Buddha was a person of superior enlightenment, he did not regard the age of human beings as of great importance. 3. On the relationship between parents and children, Buddha warned the extra ordinary attachment of parents toward children, because such attachment would be an obstacle in the search of truth. This idea was originated from his thought that the relationship between parents and children was not a single fixed one but of unlimited variation through numerous life times of reincarnation. This idea gives some illumination upon the problems of today's education where parent's exclusive attachment to their children and over-protection are hindrance for successful education. 4. Buddha put emphasis on parents' social duty, by which he meant that parents should care and accept not only their biological children but all children and all living things as if they were their own children. 5. Regardeding the children's role to their parents, Buddha taught that children should respect and support their parents under any condition. Buddha also emphasized that true filial piety was to help parents to improve their religious status by helping them attain the truth, morality, and wisdom. It is my intention to investigate Buddha's View tin children of entering pristhood.

The purpose of this study was to investigate the impact of lifestyle on the perceived value of children in university students. Questionnaires were distributed to 467 university students with questions covering topics including general personal information and characteristics, lifestyle type, and value of children. First, a cluster analysis based on lifestyle showed that the subjects could be categorized into three groups: negative-leisure types, active-achievement types, and affirmative-fidelity types. The negative-leisure type was highly leisure-oriented and showed a negative self-value; the active-achievement type showed a perspective that valued personal and occupational self-development and a high level of labor-oriented value; and the affirmative-fidelity type favored materialism, seeking occupational aptitude and worth and showing a positive self-value. Second, an investigation of the impact of these three lifestyle types on the students' value of children revealed that the active-achievement type group had high level of belief in the necessity of childbirth, the affirmative-fidelity type group highly valued fulfilling an active parent role, and the active-achievement type group were inclined to delay childbirth. Further, the negative-leisure type group wanted the lowest number of children, while the affirmative-fidelity type group wanted the highest number of children. This study reveals that university students' lifestyle does have an effect on their value of children. It is therefore proposed that a value-focused population education for increasing fertility should relate not only to individuals' value of children but also to their broader lifestyle.

Large-scale wireless sensor network are expected to play an increasingly important role for the data collection in harmful area. However, the physical fragility of sensor node makes reliable routing in harmful area a challenging problem. Since several sensor nodes in harmful area could be damaged all at once, the network should have the availability to recover routing from node failures in large area. Many routing protocols take accounts of failure recovery of single node but it is very hard these protocols to recover routing from large scale failures. In this paper, we propose a routing protocol, which we refer to as LSFA, to recover network fast from failures in large area. LSFA detects the failure by counting the packet loss from parent node and in case of failure detection LSFAdecreases the routing interval to notify the failure to the neighbor nodes. Our experimental results indicate clearly that LSFA could recover large area failures fast with less packets than previous protocols.

A series of 13- and 14-membered cyclic enkephalin analogs based on the moderately $\mu$ selective prototype compound Tyr-C[D-$A_2bu$-Gly-Phe-Leu] 8a were synthesized to investigate the structure-activity relationship. The modifications of sequence were mainly focused on two positions 3 and 5, critical for the selective recognition for $\mu$ and $\delta$ opioid receptors. The substitution of hydrophobic $Leu^5$ with hydrophilic $Asp^5$ derivatives led to Tyr-C[D-$A_2bu$-Gly-Phe-Asp(N-Me)] 7 and Tyr-C[D-Glu-Phe-gPhe-rAsp(O-Me)] 5, the peptides with a large affinity losses at both $\mu$ and $\delta$ receptors. The substitution of $Phe^3$ with $Gly^3$ led to Tyr-C[D-Glu-Gly-gPhe-rLeu] 3 and Tyr-C[D-Glu-Gly-gPhe-D-rLeu] 4, the peptides with large affinity losses at $\mu$ receptors, indicating the critical role of phenyl ring of $Phe^3$ for $\mu$ receptor affinities. One atom reduction of the ring size from 14-membered analogs Tyr-C[D-Glu-Phe-gPhe-(L and D)-rLeu] 6a, 6b to 13-membered analogs Tyr-C[D-Asp-Phe-gPhe-(L and D)-rLeu] 1, 2 reduced the affinity at both $\mu$ and $\delta$ receptors, but increased the potency in the nociceptive assay, indicating the ring constrain is attributed to high nociceptive potency of the analogs. For the influence of D- or L-chirality of $Leu^5$ on the receptor selectivity, regardless of chirality and ring size, all cyclic diastereomers displayed marked $\mu$ selectivity with low potencies at the $\delta$ receptor. The retro-inverso analogs display similar or more active at $\mu$ receptor, but less active at $\delta$ receptor than the parent analogs.
