The purpose of this study was to examine the social support network for divorced single mother families. The data were gathered through in-depth interviews with seven divorced single mothers who had at least one school-age child. Qualitative analysis of data showed that divorced single mothers evaluated themselves based on other people's perception. There were mainly three different kinds of self-images, which were “a competent divorced woman,” “a bad child to my parents,” and “a socially weak person.” We also found that there were two factors that influenced the everyday lives of single mothers: all of them .;offered hardships in living as a divorced woman with children, and they also had to deal with the weakened solidarity with family of origin, relatives, and neighbors. Single mothers shared common problems yet their lifestyles and adjustment strategies were diverse. Therefore, diverse social welfare policies for education and counseling for single mothers are urgently needed to support and empower divorced single mothers.

A survey research was conducted for a sample of 306 adult children who have an elderly parent or both parents alive. The purpose of the research was to test a structural equation model which specified the effects of early family relationships on comtemporary relationships and assistance patterns between adult children and their parents. The data were analyzed using EQS for Windows 5.7, utilizing maximum likelihood method. The results showed that early family relationships affected filial concern first, which in turn affected the level of assistance provided by adult children for elderly parents. No direct effect has been found between early family relationships and the level of assistance by adult children for elderly parents. Filial concern was played as an intervening variable. Early family relationships gave no direct effects to adult children's intention to assist their parents. Here again, filial concern was played as an intervening factor. Adult children's intention to assist their parents had not been led directly to provision of actual support to parents by their adult children. Thus, it was identified that intention to support is one thing, and the actual support is another. Controlling for the effects of filial concern, overall, early family relationship patterns gave no differential effects to the different aspects of support provided to parents by their adult children. On the basis of these results, this paper provided both discussions and suggestions for some strategies of intervention in the present family relationships in order for the inter-generational exchange of supports to happen in the future.

특이산성토와 잠재성 특이산성토 물질은 전 세계적으로 분포하며, 산성으로 인하여 농업과 환경에서 문제시되어왔다. 대부분이 퇴적기원이며 소수의 경우에 화산기원으로 보고되어왔다. 산성은 잠재성 특이산성토 물질에 함유된 유황광물의 산화과정에서 생성된 황산에 기인한다. 우리나라에서는 보고가 된바 없는 중생대 화산활동에 의하여 생성된 잠재성 특이 산성토 물질을 보고하고저 한다. 봉산통-황철석을 함유하지 않은 안산암질 모재층-황철석을 다량 함유한 안산암의 단면을 야외조사와 화학적 및 광물학적 분석을 통하여 연구하였다. 한때 택지조성과정에 황철석을 함유한 안산암이 지표에 노출되어 황철석의 산화에의한 토양과 지표수의 산성화문제가 제기된 적도 있다. 봉산통과 모재에서는 황철석과 특이산성토의 생성과정에서 나타나는 노란색 반문과 같은 특징들이 나타나지 않았다. 열수변질에 의하여 생성된 안산에 존재하는 황철석이 화산활동에 의한 열수변질 기원임을 지시해주는 육각형 또는 주사위형의 모양과 암석의 갈라진 틈을 따라 산출되는 양상 등을 보여주었다.

Steam generator(S/G) tubes in pressurized water reactor (PWR's) are subject to several types of degradation. This degradation includes denting, pitting, intergranular attack(IGA), intergranular stress corrosion cracking(IGSCC), fatigue, fretting and wear. Degradation can be derived from either the primary side(inside) or the secondary side(outside) of the tube. Recent issue for tube degradation in domestic steam generator is the tube end cracking on seal weld region. The seal weld region at the tube end and tube itself is regarded as a pressure boundary between the primary side and the secondary side. One of the Westinghouse Model-F S/G has experienced tube end cracking and its number of plugging approximately becomes to the operating limit up to 5% due to tube end cracking which was reported as SAI/MAI(single/multiple axial indication) or SCI/MCI(Single/multiple circumferential indication) from the results of eddy current testing. Eddy current mock-up test was carried out to determine the origin of cracking whether it is from weld zone area or parent tube. This result was helpful to analyze crack location on ECT data. Correct action on this problem was the installation of tube-end sleeve. Last year, after removing 340 installed plugs from tubes, selected 269 tubes took tube-end sleeve installation. Tube-end sleeve brought pressure boundary from parent tube to installed sleeve tube. Tube-end sleeve has the benefit of reducing outage period and increasing more revenue than replacing S/G. This paper is provided to assist interest parties in effectively understanding this issue.

We present an analysis of the chemical abundances and kinematics of six low-mass dwarf stars, previously claimed to be candidate hypervelocity stars (HVSs). We obtained moderate-resolution (R ~ 6000) spectra of these stars to estimate the abundances of several chemical elements (Mg, Si, Ca, Ti, Cr, Fe, and Ni), and derived their space velocities and orbital parameters using proper motions from the Gaia Data Release 2. All six stars are shown to be bound to the Milky Way, and in fact are not even considered high-velocity stars with respect to the Galactic rest frame. Nevertheless, we attempt to characterize their parent Galactic stellar components by simultaneously comparing their element abundance patterns and orbital parameters with those expected from various Galactic stellar components. We find that two of our program stars are typical disk stars. For four stars, even though their kinematic probabilistic membership assignment suggests membership in the Galactic disk, based on their distinct orbital properties and chemical characteristics, we cannot rule out exotic origins as follows. Two stars may be runaway stars from the Galactic disk. One star has possibly been accreted from a disrupted dwarf galaxy or dynamically heated from a birthplace in the Galactic bulge. The last object may be either a runaway disk star or has been dynamically heated. Spectroscopic follow-up observations with higher resolution for these curious objects will provide a better understanding of their origin.

The purposes of this study were to find the general trends of marriage-ideology reflected on the view of marriage of unmarried men and women, to estimate the differences according to related variables and to investigate relation of variables and marriage-ideology. The samples were selected from the unmarried 164 men and 235 women living in Kwang-ju. The major findings were as follows; 1. Unmarried men and women didn't reveal high level of marriage-ideology but men's marriage-ideology scores were higher than women. The overall tendencies were that women's achievement of vicarious status was more imporant than that of personal status, marriage was the male-leading union and men's conditions of mate-selection must be superior than woman. Unmarried men and women usually did not accept equality between sex and they have strong gender-stereotype. In the view of sexuality, premarital viriginity and extramarital intercourse were more rigid with woman and they took a serious view of man-centered kinship. 2. Marriage-ideology were significantly different according to mother's age, necessity of marriage, motive of marriage, marriage taboo according to family origin, the eldest son's parent care-giving, a notion of preferring a son. 3. Men and women's marriage-ideology was positively related to variables. Especially, women's marriage-ideology had high relation to motive of marriage and a notion of preferring a son. But women's marriage-ideology was negatively related to educational level. (Korean J Human Ecology 1(1) : 27∼43, 1998)

Glauconite grains are widely distributed in the outer shelf surficial sandy sediments of the Korean continental shelves. Morphologically, these grains are characterized by ovoidal-shaped pellets with bulbous exterior, greenish color and moderately well polished surface. In thin sections, the glauconite grains are massive and contain numerous impurities composed mainly of quartz, feldspar and mica. The morphologies and microscopic examinations indicate mainly fecal pellet as a parent matierials for glauconite. SEM examination shows that glauconitic smectite crystals grow in pores and along fractures of the host grains, commonly as a boxwork arrangement or rosette clusters of blades. Bulbous external shape, high potassium content and rosette-shaped smectite structure, reflect the evolved stage (more than 10$^4$ years in age) of glauconite authigenesis. Moreover, the association of the glauconite grains with the relict sandy sediments on the outer shelf, impliesthat the glauconite grains are geologically old, or at least have formed under the environmental conditions different from the present shelf. The widespread occurrence of the glauconite grains, therefore, might be primarily related with redeposition of sediments transported from the outer shelf during Holocene transgression.

One of the most striking features of modern society in the 21st century, is increased levels of aggression. Aggression refers to aggressive or hostile behavior, and is manifested in suicide or an attack against others. Aggression in modern society is more accidental, reckless, and aimless than before. As more patients visit hospitals due to the serious problem of aggression control, we need to address the nature of this growing aggression. The authors analyzed sources and the nature of aggression, based on the movie 'American Psycho.' The main character of the movie, Patrick, is similar to many people today, with traits such as egotistical thinking, lack of empathy, demand for attention and admiration, and exploited and superficial relationships. Patrick's aggression is in reaction to narcissistic injury. Through this, one can think of pathological narcissism, behind growing aggression in modern society. There are a number of social and environmental factors, attributable to increasing narcissism in modern society. Among them, change in parenting practices, and parent-child relationships, is likely to have affected increase in narcissism in terms of personality development. In conclusion, when treating patients exhibiting aggression in psychotherapy, it is critical to fully consider the possibility of pathological narcissism and its use in analysis.
