This paper attempts to identify the principle of family succession and family patterns of yangban in the late Chosun period through an analysis of male adaptation cases found in family registration records. The primary source of analysis is the family registration documents of Uiseong Kim's from the late 17th century to the early 20th century. As a result, it is found that there is a substantial change in the patterns of family from the early and mid Chosun period to the late Chosun period. The change is the strengthening of the principle of patriarchy succession through male adoption. Looking at the data as a whole, the average number of household members is increased and the membership of kinship also expanded. In contrast to the family patterns of the early Chosun period, not only the patterns of Uiseong Kim's family are predominately immediate family or collateral family but also the majority is extended family in the 18th and 19th centuries. The male adoption cases recorded in Uiseong Kim's family registration documents take up 33.8% of the male adoption cases in the entire family registration documents. This goes to show that the strengthening of the principle of primogeniture succession at a time when child mortality rate is very high resulted in the increase of male adoption. In conclusion, the late Chosun society was a society where the seat of primogeniture was much more important than immediate hereditary members in the family succession.

In this article, the women as the subject of the family management in the 19th century cataclysm, In particular, I tried to reconstruct the specific life course of a woman who has a status as a jongbu(종부) in the Korean language through the Hangul letter. The Haenam Yoon's the 8th jongbu(종부) Gwangju Lee attempted to find her own unique identity, not the male-centered social order she had learned. Because she had to live a life outside the traditional environment of traditional society because her husband died at the beginning of her marriage. She perceived herself as an independent subject that she had to find and maintain. When Gwangju Lee married and came to the family of Haenam Yun, the economic power of jong-ga(종가) was much inclined. This economic difficulty was caused by the conflict with the slaves and the decrease of tallage(地代) to the change of the slavery system which was the social flow at that time. And uncles of her husband's intervention made the economic situation of the family more difficult. She established her position as a jongbu(종부) and used the right of Adoption option(입후권) of the jongbu(종부) to establish the impoverished family. She chose adoption from distant relatives who were not children of her husband's uncles. Therefore, I was free from her husband uncle's interests. She also believed that it was most important to take control of the economic interests of her family in order to secure her authority as a jongbu(종부). She believed that she had to exercise her economic rights in order to bring slave labor, which is the most important means of sustaining the domestic economy at the time, In the absence of her husband, she established her family in the social upheaval of the nineteenth century, and took her place as a master of a family, not just a family name.

The purpose of this study is to investigate the level of knowledge that mothers have on child development. To do so, a Knowledge of Child Development Inventory(KCDI) developed by Larsen &Juhasz(1986) was carried on to 156 mothers with an infant range from birth to age 24 months. The findings of the study were twofold: First, 70% of the questions on average were answered correctly by the participants. In other words, mothers generally demonstrated a high level of knowledge on child development. With regard to knowledge of child development, their knowledge on physical development of children was relatively low in comparison with that of cognitive and emotional development. In addition, mothers with a girl were more aware of child development especially in relation to child's emotional development. Also, mothers who delivered a heavier baby at birth possessed a higher level of knowledge concerning child's physical development. Second, other external factors, such as the level of family income and mother's education, played a significant role in affecting the level of knowledge on child development. Unsurprisingly, mothers with a higher income and education level demonstrated a higher level of knowledge on child's cognitive development. The findings of the study implicates that mothers seldom demonstrate a proper level of knowledge on child development. Hence, this study suggests that a practical, functional training services and resources for current and future mothers must be ensued.

This study analyzed the policies related to parents in child care centers from 1991 to 2013 as shown in the guidance for child care business book published by the government and accredited journals by the National Research Foundation. Policies related to parents in child care centers were divided into the following periods: 1) the period of passive parent education focused on low-income families (1991-1994), 2) the period of relief for dual-income families (1995-1997), 3) the period of relief for adoption families and the practice of child care support services (2004-2007), 4) the period of active parent involvement (2008-2013). On the other hand, the research trends of parent education in child-care centers were as follows: 1) the survey of parent education was the most common at first, 2) the studies of the role and disposition of parents occupied the bulk, 3) the studies of parents' needs and satisfaction on parent involvement appeared plenty, 4) the studies of the personalized parent education increased. Consequently, the need for home care services and the importance of parents' education were suggested.

Objective：This study was performed to identify and understand the characteristics of adolescents who had a history of police arrest and/or were adjudicated unruly/delinquent by the juvenile court. Method：The study employed a retrospective reivew of coumputer-recorded data set on 210 consecutive admissions to an adolescent psychiatric inpatient unit. Three groups(No Police Contact, N=115；Police Contact Only, N=60；Adjudicated, N=35) were compared on the areas of a) cognitive and educational performance b) emotion：anxiety, depression, suicidality c) personality d) family and life experiences. Standardized assessments were administered to all subjects using WISC-Ⅲ, Kaufman Test of Educational Achievement, Millon Adolescent Personality Inventory, Reynolds Adolescent Depression Scale, Revised-Chilren’s Manifest Anxiety Scale, Suicide Ideation Questionnarie, Suicide Behavior Interive, Life Events Checklist, and Family Environmental Scale. A subgroup of the subjects, 60 cases also received a standardized interview by Child Assessment Schedule. Results：The characteristic findings of the delinquent group(the police contact only and adjudicated subjects combined) included (1) a high rate of adoption, sexual promiscuity, out of home placement, and repeated psychiatric hospitalization, (2) low verbal IQ scores and educational achievements, (3) high impulsivity, low social conformity, and high forcefulness in personality inventory, (4) low activityrecreation orientation and low moral religious emphasis in family environment, (5)a high frequency of adverse life experiences, (6) among 3 groups, the Police Contact Only group showed the lowest depression, anxiety and suicidal ideation scores, (7) a high diagnostic frequency of conduct disorder, ODD, and ADHD. Conclusions：The adolescent psychiatric inpatients with a delinquent history presented with a certain clinical, family, psychometric characteristics that warrant specific clinical intervention strategies for their cognitive deficits, an impulsive personality style, family dysfunction with adverse life experiences and disruptive behavioral disorders, different from the rest of adolescent psychiatric inpatients.

The electrochromic properties of vacuum deposited V$_2$O$_{5}$ thin films as a function of crystallinity and film thickness have been systematically investigated. The as-deposited films have slightly yellow appearance. V$_2$O$_{5}$ films deposited at higher substrate temperature(>14$0^{\circ}C$) are found to be crystalline while those deposited at low substrate temperature are amorphous. The optical modulation on lithium ion injection indicates that V$_2$O$_{5}$ films exhibit anodic coloration in the 300~500 nm wavelength range and cathodic coloration in the 500~1100nm wavelength range independent of crystallinity and film thickness. The optical band gap energy of crystalline and amorphous Li$_{x}$ VV$_2$O$_{5}$ films shifts to higher energies by 0.17 eV and 0.75 eV, respectively, with increasing lithium ion injection up to x=0.6. The coloration efficiency of amorphous Li$_{x}$ V$_2$O$_{5}$ exhibits very little dependence on film thickness and lithium ion injection amounts in the near-infrared while it increases significantly with increasing film thickness and decreasing lithium ion injection amounts in the blue and near-UV due to the shift in absorption edge below around 500nm. However, the coloration efficiency of crystalline Li$_{x}$ V$_2$O$_{5}$is relatively independent of film thickness and lithium ion injection in the 300~1100 nm wavelength range.

Objectives: The aim of this study was to find out the attitude of Korean women towards IVF surrogacy which is not yet regulated by the law. Methods: We evaluated with a questionnaire, in how far IVF surrogacy was accepted in different groups of Korean women. Total 300 questionnaires were sent out to women who visited our infertility clinic, and to the nurses and office workers of our hospital. Among them, 246 questionnaires were returned, and 211 of them (85.7%) were complete and analyzed. The responders were 58 unmarried women and 153 married women including 60 infertile patients. Results: Only 17 (8.1%) women believed that IVF surrogacy was an acceptable treatment for infertile women without uterus (eg. MRKH or hysterectomized patients), and 125 (59.2%) women chose the adoption. There were no significant differences in response amongst different age group, marital status, or in relation to income level or educational level, or infertility status. A significantly higher level of acceptance was noted only in religious groups, especially in Christians. Most of responders (66.5%) chose unrelated and unknown women as a desirable host, and 28.4% of responders chose the sister or sister-in-law. Conclusions: Overall the different groups were critical towards IVF Surrogacy in Korea, irrespective of the infertile patient group. Despite the established clinical ability to have her own genetic child in women without uterus, this survey reveals that only minority supports the IVF surrogacy. So we need the survey with large, randomized population and then make a regulation about the IVF surrogacy in law.

Canine infectious respiratory disease (CIRD), also known as infectious tracheobronchitis or kennel cough occurs in a multiple-dog environment such as a shelter. In this study, we were collected 300 of nasal swab samples from dogs and 145 of environmental samples from a shelter to investigate respiratory pathogens of dogs in the Gwangju metropolitan city animal shelter from February to October, 2019. Bacteria cultures for isolation of Bordetella (B.) bronchiseptica and polymerase chain reaction (PCR) tests were performed for detection of eleven canine respiratory pathogens, namely Mycoplasma (M.) cynos, canine distemper virus (CDV), canine influenza virus (CIV), canine parainfluenza virus (CPIV), canine respiratory coronavirus (CRCoV), alpha-coronavirus (CCoV), canine pneumovirus (CnPnV), canine hepacivirus (CHeV), canine adenovirus type 2 (CAdV-2), canine herpesvirus-1 (CHV-1) and canine bocavirus (CBoV). Among 300 nasal swab samples, 148 samples (49.3%) were positive for at least one pathogens. CHV-1 was the most common pathogen, found in 95/300 (31.7%) samples. Subsequently, M. cynos (22.0%), B. bronchiseptica (2.3%), CPIV (2.0%), CBoV (1.7%), CCoV (0.7%) were detected. The detection rates of M. cynos and CHV-1 according to the duration of stay in the shelter were statistically significant. Among environmental samples, M. cynos, CCoV, CBoV and CHV-1 were detected in 45/145 (31.0%). These results indicated the need for disease control and prevention systems in the shelter.

Spatio-temporal variations of long-term water qualities (COD, SS, $Chl-{\alpha}$, N-related nutrients (TN, TDN, $NO_3^-$, $NH_4^+$), P-related nutrients (TP, TDP, $PO_4^{3-}$)) at two stations (St. SD, St. GG) in the Geumgang Reservoir were investigated from August 2001 to July 2008. Statistical methods such as t-test, factor analysis, and multi-regression analysis were applied to the water quality data in the reservoir as well as mass balances on TP. From the temporal comparisons of the water qualities between 2002 and 2007, average concentrations of $NH_4^+$, $PO_4^{3-}$, and TDP gradually decreased down by 60%, 24%, 52% in 2007. However, those of TP and $Chl-{\alpha}$ increased to 99% and 423% during the period. From the spatial comparisons between the two stations, St. GG showed higher concentrations for all of the N- and P-related nutrients than in St. SD, while opposite result for the $Chl-{\alpha}$. The factor analysis showed that "the seasonal variations of N- and P-related nutrients" were the two dominant factors occupying 49% of total variances of water qualities. Based on this result, multi-regression analysis executed for the two most influential parameters (TP and $Chl-{\alpha}$) focusing on the seasonal variations of these parameters: SS and $Chl-{\alpha}$ has contributed decisively to the concentrations of TP during the wet and dry season, respectively. On the other hand, COD and TP has been important for the $Chl-{\alpha}$ during the wet and dry season, respectively. From the established mass balances of TP loadings in the Geumgang Reservoir, Other Sources (60%) occupied the greatest contribution and Fluvial Input (38%) and Sediment (1%) during the wet season. However, both Fluvial Water (48%) and Other Sources (47%) supplied comparable amount of inputs and Sediment (5%) showed significantly increased input during the dry seasons. Recently especially during the dry winter seasons, migrating bird's excretion was estimated to contribute up to 8% of total TP input and 21% of Other Sources.
