기계학습에서 커널을 이용한 방법은 그 응용범위가 기계학습의 전반에 걸쳐 다양하게 이용되고 있으며, 그 성능 또한 기존의 방법들을 앞지르고 있다. 이는 기존의 비선형적 접근을 커널을 이용한 고차원 공간에서의 선형적 접근법으로 바꿈으로써 가능하게 되는 것이다. 다양한 분야에 적용되는 많은 커널들이 존재하며 각 커널들은 특별한 분야에 적용되기 쉽도록 다른 형태를 띠고 있기도 하지만, 커널로서 작용하기 위해 양한정 조건(positive definiteness)을 만족해야 한다. 본 연구에서는 DNA 문제에 직접 적용시킬 수 있는 방법으로서의 새로운 커널을 제시한다. 또한 매트로폴리스(Metropolis) 알고리즘을 이용하여 DNA의 hybridization과정을 모사함으로써 새로운 종류의 커널이 양한정(positive definite) 조건을 만족시킬 수 있는 방법을 제시한다. 새로 만들어진 커널이 행렬값을 형성해 나가는 과정을 살펴보면 인간이 예(instance)로부터 개념을 형성해 나가는 과정과 흡사한 양상을 보이는 것을 알 수 있다. 개념을 나타내는 좋은 예로서의 표본(prototype)으로부터 개념이 형성되어 가는 과정은 표본(prototype)이 아닌 예로부터 개념이 형성되는 과정과 다른 양상을 띠는 것과 같은 모양을 보인다.

Flow theory has been borrowed from psychology to address positive user experiences with computers and Internet. The flow experience in computer-mediated environment (CME) has been correlated to increased communication, loaming, exploratory behavior and positive affect. A comparative experiment between CME and traditional paper-pencil environment was conducted to verify whether particular environments or interfaces are more conducive to yielding flow among users. The results showed that there were no differences in flow dimensions except 'enjoyment' between CME and paper-pencil environment. But the distorted senses of time among users were significantly different between the media environments.

In order to examine the antecedents of socially reticent, solitary passive and solitary active behaviors in preschoolers, 38 2 year olds were observed in Kagan's(1989) traditional behavioral inhibition paradigm and thereafter, at age four, in a same age, same sex quartet of peers. Correlation analysis revealed the independent and unique nature of solitary passive, solitary active and reticence behaviors at age 4 suggesting the heterogeneity of the three forms of solitude during the preschool period. Regression analysis indicated that associations between 2 year old inhibition and shyness and 4 year old reticence were positive when mothers demonstrated a high frequency of over protectiveness; similarly, associations between 2 year old inhibition and shyness and 4 year old solitary active behavior were significant and positive when mothers demonstrated high frequencies of authoritarian behavior.

The purpose of this study was to investigate the effects of science instruction using integrative educational model on academic achievement and scientific attitude in gifted classes on elementary science. Integrative educational model (hereafter referred as IEM) was developed by synthesizing the findings from brain research, the new physics, general systems theory, and educational psychology. 77 6th graders of B Metropolitan City's Elementary Gifted Education Center were took part in this study. The experimental group, consisting of 39 students, was applied to the instruction using IEM, while the comparison group, 38 students, was applied to instructor- led instruction. The results of this study were as follows: First, the science instruction using IEM had a positive effect on improving achievement in gifted classes on elementary science. Second, the science instruction using IEM had an influence on inquisitiveness and openness of the lower domains of learners' scientific attitude. Third, the science instruction using IEM had a positive response to learners' interest, comprehensibility about lesson contents, and ability to concentrate on classes.

Emotional expressiveness is a pathway by which parents affect the emotional competence of their children. This study examined how the emotional expressiveness of parents is influenced by the emotional reactions of their children and demographic characteristics within a family context. Data for the present study were from 200 parents in 100 two-parent families who completed self-report questionnaires for emotional expressiveness, children's emotional reactions to stressful situations, and demographics. In preliminary analyses, mothers expressed emotions more frequently than fathers did, and mothers with high expressiveness of positive emotions were more educated and had higher family income. Although fathers' emotional expressiveness was closely related to mothers' expressiveness, none of the demographic factors were related to fathers' expressiveness. When all predictors were considered in hierarchical multiple regressions, family income was the significant predictor for mothers' positive expressiveness, whereas mothers' negative expressiveness were explained by children's emotional reactions, mother education, child sex, the number of siblings, fathers' education, and mothers' time spent with children. When controlled for mothers' expressiveness, fathers' time spent with children was the only significant predictor for fathers' negative expressiveness. The results of this study suggested that parents' emotional expressiveness varied with socioeconomic status. The discussion also examines the gender differences between mothers and fathers in emotional expressiveness, and their relations to children's sex.

As people's income rises dramatically, people's happiness seems not as high as expected. In fact, there are two different arguments about the relationship between income level and happiness. The focus of the debate is whether the correlation between income and probability of happiness is positive or negative. Therefore, we hypothesizes that the relationship between income and probability of happiness presents an inverted U-shaped curve. Then, this paper sets China as an example to explore the effect of income on happiness. The data from the Chinese General Social Survey (CGSS) in 2015 is employed to conduct empirical analyses under the Probit model and the Zero-Inflation-Passion model. The empirical findings indicate that the effect of income on happiness presents an inverted U-shaped curve and significantly in statistic. Meanwhile, spouse's income, educational level, marriage time and house property have a positive and significant effect on happiness. Conversely, age and local living standards have a negative and significant effect on happiness. Unfortunately, even though registered residence and children have a negative effect on happiness, they do not get through the significant test. In order to ensure the robustness of our empirical results, we test the robustness of the above empirical results by adjusting the sample size. The results of robustness test verify that our empirical results are robust. Moreover, this paper also makes a small contribution to the current literature with a sample from China.

The main purpose of this study was to assess the effects of SES, mother's psychological well-being, child-rearing behavior and child's peer relationship on school adjustment. A total of 237 children enrolled in the 5th and 6th grade and their mothers were used for this study. Data was collected via questionnaires completed by children and their mothers. The path analysis of antecedent variables influencing child's school adjustment revealed two different patterns. Firstly, socioeconomic status influenced child's school adjustment through maternal psychological well-being. Secondly, maternal psychological well-being affected by socioeconomic status contributed to child's school adjustment through positive child-rearing behavior and positive peer relationship. Focusing on maternal psychological well-being and mother's child-rearing behavior, the implication for promoting child's school adjustment are discussed.

Human resource management has always been the most important part of any organization (corporate and government-owned). Until whenever improvement in human resource management is always the background of every problem that occurs in the organization. This study aims to examine the relationship of procedural justice and organizational commitment to OCB satisfaction and job satisfaction in the Public Works Office of Kutai Kartanegara Regency. Sampling involved the entire population, i.e. 109 informants. They are employees who have goods and services certificates. Hypothesis test carried out with the SEM-PLS model in two stages (outer model and inner model). After that, the survey data was used SMART PLS 3.0. Based on empirical findings, we find that procedural justice has a positive and significant effect on OCB, while organizational commitment does not. Procedural justice, organizational commitment, and OCB have had a positive and significant effect on job satisfaction. The novelty of the study lies in the originality value that describes the conditions in a government agency with different benchmarks (variables and indicators) from previous studies, so it is very interesting and varied.

Based on the love styles theory used in psychology, this paper classifies users(Passionate Love, Game-playing Love, Friendship Love, Practical Love, Possessive Love, Altruistic Love) and investigates satisfaction with the motivation for using TikTok love videos(Entertainment, Social Relationship, Love skills-learning, Self-verification, Problem-solving) according to the theory of use and satisfaction. First, 414 users were selected to conduct TikTok surveys to collect data. Then, through the analysis of the research results, among the six love types, game-playing type and possessive type have a positive (+) impact on entertainment motivation and love skill-learning motivation. Game-playing type also have a positive (+) impact on social relationship motivation and self-verification motivation. In addition, altruistic type and possessive type are also factors to strengthen the motivation of self-verification. The altruistic type, possessive type and practical type will improve the problem-solving motivation. Finally, through hierarchial multiple regression analysis, it is confirmed that game-playing love type, entertainment motivation, love skill-learning motivation and self-verification motivation can improve user satisfaction. The above results enrich the research of user classification as well as providing inspiration for improving the quality and communication efficiency of TikTok's video and enhancing user experience.
