The purpose of this study was to identify transition conditions, health behavior and indicators of healthy transitions among middle-aged women based on Schumacher & Meleis(1994) transition model for developing intervention program for their health promotion. A convenience sample of 221 women aged 40-60 was obtained in Jung-Gu, Seoul and they were asked to complete the questionnaires, which consisted of modified health-promoting lifestyle profile(HPLP), knowledge of menopause, physical well-being, emotional well-being, modified women's role integration protocol (WRIP), Beck's Depression Inventory(BDI), and indicators of healthy transition with subcategories such as subjective well-being, role mastery and well-being of interrelationship. The results were as follows: 1. Women had a mean age of 47.53 years. More than half(53.39%) of the women had jobs and 88.69 % had their spouses, Of 221 women, 51.13 % were premenopausal, 19.91% were perimenopausal, and 28.96% were postmenopausal. 2. Women scored lower on health responsibility and exercise than on self actualization, nutrition and interpersonal support among subcategories of health behavior measured the modified HPLP. Only 11.98% of respondents had breast-self examination and 42.66% had pap smear for screening cancer. 3. In transition conditions, women had poor knowledge about menopause and median level of physical well-being, emotional well-being and stress. 15.45% of the women had clinical depression. 4. As for the outcome index of the transition model, the mean of indicators of healthy transition was 3.69(possible range 1-5). 5. The levels of education and economic and the menstrual status were significantly related to physical well-being, depression and stress in the categories of transition conditions. The total score of health behavior correlated negatively with depression. The total score of indicators of healthy transition correlated with physical well-being, emotional well-being, stress, and depression in the categories of transition conditions. In conclusion, these findings suggested a profile of fragile middle-aged women and contributed to developing the community-based intervention program for health promotion.

Purpose: The purpose of this study was to investigate the kinematic characteristics and muscle activities during the following two conditions: transition from half-kneel to standing on the affected leg and non-affected leg. Methods: Twenty-one hemiplegic patients participated in the study. A motion analysis system was used to record the range of motion and angle velocity of the hip, knee and ankle from the half-kneel to the standing position. Electromyography was used to record the activity of 4 muscles. Results: The statistical analysis showed that the minimum ROM of the hip joint was less on the affected leg during transition from half-kneel to standing. However, the minimum ROM of the knee and ankle joints was less on the non-affected leg during transition from half-kneel to standing. The angle velocity of the knee and ankle joints was less during transition from half kneeling to standing on the non-affected leg. Muscle activity of the rectus femoris and tibialis anterior was less while moving from half-kneel to the standing position on the affected leg. Conclusion: These results show that greater active ROM of the knee and ankle was required on the affected leg for transition from half-kneel to the standing position than for normal gait. Muscle activity of the rectus femoris and tibialis anterior is normally required for movement from the half-kneel to the standing position during normal gait. Further studies are needed to investigate the antigravity movement in healthy subjects and hemiplegic patients in order to completely understand the normal and abnormal movement from the half-kneel to the standing position.

Purpose: Although the term "transition to motherhood" is commonly used in research, the concept is not clear. This study, hence, was conducted to clarify the concept of "transition to motherhood." Methods: The concept analysis framework developed by Walker and Avant is used to analyze the concept of transition to motherhood. Results: Transition to motherhood is defined as the physical, psychological, social, and relational (mother-baby relationship/interpersonal relationship) changes that happen to a woman after pregnancy and delivery of a baby. The attributes of the transition to motherhood include: 1) adapting to physical changes after pregnancy and childbirth; 2) experiencing various psychological changes; 3) changing of her social perception from being a woman to someone's mother; and 4) forming and developing a relationship with the newborn, adjusting priorities, and redefining the relationship between family and others. Meeting the newborn is regarded as an antecedent of the transition to motherhood. Redefining identity and physical image, ensuring mother's well-being, maternal attachment, and confidence in the maternal role are regarded as consequences of the transition to motherhood. The concept was clarified by the presentation of model, borderline, and contrary cases. Conclusion: The significance of this study lies in the clarification of the concept of transition to motherhood and defining its attributes. It is recommended that tools be developed to measure transition to motherhood based on the results of this study. Furthermore, nurses and midwives can use study findings to better understand the concept of transition to motherhood in providing care and support to mothers who experience it.

The society changes very fast from the extended family system to the nuclear family system, as increasing a one-child family for the low birth-rate. Thus, it causes that the education, having been performed inside of the family group, is performed outside of the family nowadays such as an infant educational institution. Fundamentally, the space of educating infants must be considered their behavior and meet their needs. For infants, playing is not only studying, but also is related to physical, intellectual and emotional development. Therefore infants in a qualifiedly good playing environment, are easy to focus on their playing. But, variety of playing activities can help improve infants' development physically, socially, emotionally, linguistically and intellectually. So far, an infant educational institution has provided a general education than a special educationally considering their age and status of a development. However, it is necessary to provide an integrated and well-organized place for each infant because their playing is a studying and education that will be based of individuals' character when they are grown up. The objective of this thesis is to study on the new transition space for infants of their physical activities. For this study, at first, it is important to understand what are the points of well-built kindergarten around the world. They have the flexible space in common. The transition(flexible) space will be a solution for space for infants' development.

Differential Scanning Calorimetry (DSC) and solvent swelling technique have been applied for identifying physical transition temperatures in the macromolecular structure of coals. The transition processes seem to be associated with physical relaxation of the coal structure and are irreversible processes. In Pittsburgh No. 8 high volatile bituminous (hvb) coat one physical transition was noted at 250-30$0^{\circ}C$ (at 8$^{\circ}C$/min) without any significant accompanying weight loss. Coals of higher rank than high volatile bituminous, i.e., Upper Freeport medium volatile bituminous (mvb) and Pocahontas No.3 low volatile bituminous (lvb) coals, exhibit structural relaxation just before the major thermal decomposition process and a sharp increase in solvent swellability accompanies this relaxation. In the case of both the Pittsburgh No.8 and the Upper Freeport coat structural relaxations at around 36$0^{\circ}C$ seem to coincide with release of "guest molecules".les".uot;.

A Co-C eutectic cell for thermocouple calibration was manufactured and tested to investigate its phase transition characteristics using Type B thermocouples. It was observed that the freezing plateaus were flatter than those of melting, but the melting points were closer to the true transition temperature than the freezing points. The expanded uncertainty of melting temperature was calculated not to exceed $0.2^{\circ}C$ (k = 2). Based on the observed results, the melting process is recommended for the calibration of thermocouples.

The side chain liquid crystal triblock copolymers (TBCs), which underwent phase transitions below their decomposition temperature, were prepared by copolymerization of poly(n-butyl acrylate) and a comonomer containing the mesogenic azobenzene group. The physical properties of TBCs in the distinctive transition temperature ranges were investigated in terms of the liquid crystal (LC) content in the copolymers. The phase transition temperatures traced optically, thermally and rheologically were well coincided one another and clearly exhibited the phase transition of smectic-nematic-isotropic with increasing temperature. In the smectic phase, increasing temperature made the liquid crystal system more elastic, but viscosity (${\eta}'$) remained almost constant. In the nematic phase, increasing temperature abruptly decreased ${\eta}'$ and G', ultimately leading to isotropic phase. Both smectic and nematic phases exhibited Bingham viscosity behavior but the former gave much greater yield stress at the same LC content.

Organic-inorganic halide perovskite single crystals undergo phase transition of being cubic, tetragonal, or orthorhombic depending on the temperature. We investigated the $CH_3NH_3PbBr_{3-x}I_x$ single crystals grown by the inverse temperature crystallization method with temperature-dependent UV-Vis absorption and photoluminescence. From the temperature-dependent absorption measurement, the optical band gap is extracted by derivation of absorption spectrum fitting and Tauc plot. In our results, $CH_3NH_3PbBr_{3-x}I_x$ single crystals show that an abrupt change in optical band gap, PL peak position and intensity appears around 120 K - 170 K regions, indicating the phase transition temperature.

This study uses the life course perspective to analyze the health effects of care transition types on elderly persons who care for their spouses. To this end, the care transition types were divided into ① non-care→non-care, ② non-care→care, ③ care→care, and ④ care→non-care, and health was defined as physical health and the absence of depression. The study used the second through sixth datasets(2008-2016) from the Korea Longitudinal Study of Aging. This resulted in 10,199 observations from 3,987 persons, which were analyzed as a panel analysis model using the STATA16.0 program. The analysis found that physical health was lower in the non-care→care and care→non-care transition types than in the non-care→non-care type. Depression increased in the non-care→care and care→care types. These results suggest that practical and social measures are needed to improve physical health and depression in the elderly who are providing care for their spouses.
