본 연구는 생활시간조사자료를 활용하여 가구 내에서 배분되는 일-가족시간에 대한 실증분석을 수행하였다. 부부의 유급노동시간과 가족시간에서 차지하는 남성의 비중을 근거로 일-가족 시간 배분을 4개의 모형(전통적 남성생계부양, 이중노동부담, 협조적 적응, 가족친화적 남성생계부양)으로 유형화하였으며, 퍼지셋이상형분석을 통해 각 유형에 소속되어 있는 정도를 점수화한 후, 각 모형의 소속점수에 대한 중다회귀분석을 수행하였다. 연구결과, 지난 10년간 이중노동부담의 비중이 감소하고 협조적 적응 유형이 증가한 것으로 나타나고 있으나, 여전히 전체적인 모형별 분포를 보면 전통적인 성분업에 고착된 구조를 보여주고 있었다. 4개의 시간배분 모형에 대한 회귀분석 결과 역시 각 모형별 분석의 유용성을 보여주었으며, 무엇보다 성분업 의식의 역할은 제한적인 것으로 나타났다. 이를 바탕으로 향후 가족정책의 논의에 있어 가구내의 미시적 성분업 구조와 일-가족시간의 배분과 관련된 역동성을 좀 더 면밀히 파악할 필요가 있다는 점과, 방법론적 함의로 미시자료를 이용한 양적연구에서도 퍼지셋 활용이 방법론적 다양성을 제공해 줄 수 있다는 점을 논의하였다.

This study identified and compared family values within and across different generations concerning gender roles, attitudes toward diverse families, children, and parental roles. Data were obtained from the 2020 Seoul Family Report Survey. There were 1,949 study subjects, including first- and second-generation baby boomers and individuals in generations X, Y, and Z in Korea. Latent profile analyses were conducted using M-plus. Perceptions and views concerning family values were classified into different types. The main findings were as follows. Two types were identified among first baby boomers, and three were identified among second baby boomers. Most of the first and second baby boomers belonged to the "moderate" type. Two types were detected among those in Generation X. Regarding gender roles, most views of Generation X were slightly progressive, while their other family values were more moderate. Three types were identified among those in Generation Y: "progressive," "moderate," and "very liberal." Generation Z was identified as a "progressive" group. This study provides basic data to explore the direction of the coexistence of generations by identifying and comparing diverse family values within and across generations.

The previous morphology-based taxonomic frameworks within the family Syngnathidae had emphasized the significance of the male brood pouch and reproductive biology in defining the group. However, several different hypotheses had been proposed by different investigators. This study has been carried out to determine the phylogenetic relationships among 19 species belonging to the order Syngnathiformes with three Gasterosteiformes species as outgroup taxa by using the mitochondrial cytochrome b DNA sequences. Phylogenetic analyses based on neighbor-joining distance, maximum parsimony, minimum evolution and maximum likelihood method strongly supported that the family Syngnathidae, the suborder Syngnathoidei and the order Syngnathiformes were all monophyletic group. Although much of previous morphological analyses were supported by our molecular data, there were some significant discrepancies between molecular and morphological work. Such an interesting result was that the weedy seadragon (Phyllopteryx taeniolatus) strongly grouped together with the New Zealand pot-belly seahorse (Hippocampus abdominalis). Considering the markedly different brooding structure between them, this unexpected result might be explained whether by multiple independent origins of brooding structure or by hybridization between the female Hippocampus and other syngnathid species having individual membranous egg compartment. In addition, the suborder Aulostomoidei was paraphyletic group because the shrimpfish (Aeliscus strigatus), belonging to the family Centriscidae, always grouped together with the family Syngnathidae as a sister taxon.

Detailed morphological studies and molecular analyses based on plastid-encoded rbcL gene sequences were undertaken on Peyssonnelia species, a poorly known genus from Korea. We report new records for the Korean coast, Peyssonnelia harveyana and P. rumoiana. Peyssonnelia harveyana is chiefly characterized by P. rubra-type anatomy, closely packed perithallial filaments in firm matrix, hypothallial filaments arranged in parallel rows, thalli with appressed margins, hypobasal calcification, and unicellular rhizoids. Peyssonnelia rumoiana is principally characterized by two vegetative features, hypothallial filaments arranged in a polyflabellate layer, and perithallial filaments arising from the whole upper surface of each hypothallial cell (Peyssonnelia rubra-type anatomy). Our rbcL analyses revealed that P. harveynana and P. rumoiana were placed within a clade of Peyssonnelia. We also propose the new combination, Sonderophycus cauliferus comb. nov., for previous Peyssonnelia caulifera. Phylogenetic analyses revealed that our S. cauliferus was placed within a clade of Sonderophycus.

However, several different hypotheses had been proposed by different investigators. This study have beencarried out to determine the phylogenetic relationships among 19 species belonging to the order Syngnathiformes with three Gasterosteiformes species as outgroup taxa by using the mitochondrial cytochrome b and Rag2 nuclear DNA sequences. Phylogenetic analyses based on neighbor-joining distance, maximum parsimony, minimum evolution and maximum likelihood method strongly supported that the family Syngnathidae, the suborder Syngnathoidei and the order Syngnathiformes were all monophyletic group. Much of previous morphological analyses were supported by our molecular data, but some deep relationships were not clearly resolved with regard to members of the suborder Aulostomoidei.

Significant costs to the public and private sectors due to recent extreme wind events have motivated the need for systematic post-hurricane damage data collection and analysis. Current post disaster data are collected by many different interested groups such as government agencies, voluntary disaster relief agencies, representatives of media companies, academicians and companies in the private sector. Each group has an interest in a particular type of data. However, members of each group collect data using different techniques. This disparity in data is not conducive to quantifying damage data and, therefore, inhibits the statistical and spatial description of damage and comparisons of damage among different extreme wind events. The data collection does not allow comparisons of data or results of analyses within a group and also prohibits comparison of damage data and information among different groups. Typically, analyses of data from a given event lead to different conclusion depending upon the definition of damage used by individual investigators and the type of data collected making it difficult for members of groups to compare the results of their analyses with a common language and basis. A formal method of data collection and analysis-within any single group-would allow comparisons to be made among different individuals, hazardous events and eventually among different groups, thus facilitating the management and reduction of damage due to future disaster. This research introduces a definition of damage to single family dwellings, and a common method of data collection and analysis suited for groups interested in regional characterization of damage. The current state-of-data is presented and a method for data collection is recommended based on these existing data collection methods. A fixed-scale damage index is proposed to consider the damage to a dwelling's feature. Finally, the damage index is applied to three dwellings damaged by Hurricane Iniki (1992). The damage index reflects the reduced functionality of a structure as a single family detached dwelling and provides a means to evaluate regional damage due to a single event or to compare damage due to events of different severity. Evaluation of the damage index and the data available support recommendation for future data collection efforts.

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.

본 연구는 가족 구성원들이 가족과 사회에서 지위 극대화를 위해, 가족 내외적으로 동시적 경쟁을 하는 상황을 이론화한 가족동맹 모델을 한국복지패널조사 1차년도 자료를 이용해서 검증하였다. 이 검증을 위해, 아내의 경제적 지위와 각 배우자의 가족관계 만족도 사이의 관계가 조사되었다. 분석 결과, 대체로 조사 가설들이 지지되었다. 아내들은 남편 대비 자신의 상대 소득이 높을 때, 가족관계 만족도가 낮았고, 이는 저소득층 아내들 사이에서 더 뚜렷하게 나타났다. 한편, 남편들의 가족관계 만족도와 아내의 상대 소득 사이의 양-방향의 관계가 중산층 남편들 중에서 뚜렷하게 나타났다. 그러나 예상과 달리 이 양-방향의 관계가 저소득층 남편들 중에서는 나타나지 않았다.

The brown algal family Chordariaceae sensu lato is a focus of taxonomy because recent studies suggest a broad concept of the family, including genera formerly classified in the Dictyosiphonales. Using morphology, plastid rbcL and nrDNA ITS sequences, we evaluated relationships of the monotyic genus Soranthera (S. ulvoidea), which has been classified in the Punctariaceae. The species occurs in Bering Sea and Aleutian Islands, Alaska to Baja California. Thalli are globose to lobed, hollow, 3-5 cm in diameter, and covered with evenly distributed sori. However, two forms within the species are recognized: f. ulvoidea for globose forms and f. difformis for lobed forms. Plastid rbcL and nuclear ITS region sequences were newly determined in samples of S. ulvoidea from the Pacific coast of the North America. We found little variations in the ITS sequences among samples of S. ulvoidea from five different locations and in the rbcL region from two different locations. These results do not support previous classification of f. ulvoidea and f. difformis within the species. All analyses of our rbcL sequence dataset show that Soranthera was placed in the Chordariaceae s.l., but more related to Botrytella than Punctaria and Asperococcus.
