  • Concept analysis is a strategy that examines the attributes or characteristics of a concept. It is a formal linguistic exercise to determine those defining attributes. The basic purpose of concept analysis is to clarify ambiguous concepts in theory, and to propose a precise operational definition which reflects the theoretical base of the concept. The concept of maternal role is too broad and variable in expression, therefore there has been no authentic definition nor standard opinion for this concept. The purpose of this study is to clarify the concept of maternal role which in turn will help in the development of a theory of maternal role attainment. In order to analyze the concept of maternal role, much effort was extended to look up "maternal role" in various dictionaries and literature, but only a few cases were found which listed this terminology. Consultation on the meaning of "mother" and "role" separately was then done and consequently a definition of "maternal role" was obtained through concept analysis of these two words independently, finding their attributes and unifying them. The attributes of the concept of maternal role which was analyzed based on the steps of concept analysis by Walker & Avant (1988) are : 1) Women who have pregnancies 2) Women who have a child 3) Women who rear a child 4) Expected behavior according to social status 5) Learning through social cultures 6) Social interrelationships. The antecedents of the maternal role are : 1) women who are pregnant and deliver a baby, must keep in contact with their child. 2) Circumstances for childrearing must be provided. 3) Formation of self-concept as mother should be developed, cognitive activity, which is necessary for the nurturing activity, financial support and preparation of childrearing should be provided. And the consequences of the maternal role are : 1) Improvement 2) Changeability 3) Ambiguity 4) Stability Through this concept analysis, the concept of the maternal role is defined as "expected behavior by social interrelationships and learned nurturing behavior through social cultures."

  • Network models for pedestrian flows have been studied in various ways. However, because of the simplicity and application, a number of researchers prefer the CA Model to analyze pedestrian's complicated behavior. These kinds of models based on Agent are being used as a microscopic analyzing method since it can easily adapt individuals' various characters and movement types. However, because pedestrians' movement can be (easily) effected by where they are and where they head, some models using the same rules have limit when considering pedestrians' every different movement. In this research, homogeneous section is defined as a similar movement type of individuals. With MDPM, we suggest simulation method explaining one-way walk and side-walk which could not be done in past.

  • Phase I of the Trials of Hypertension Prevention was a multicenter, randomized, controlled trial designed to determine the efficacy of seven nonpharmacologic interventions in reducing blood pressure among persons with high-normal diastolic blood pressure. the initial goal for recruitment was to enroll 2,100 participants over a nine-month period. The yield from the first screening visit to randomization was 13% overall, with clinic-specific yields ranging from 4.5% to 31.7%. After five months of recruitment, approximately 60% of the goal for that point in the recruitment timetable had been randomized. Clinical centers falling short of their goals at that time altered their recruitment strategies and intensified their efforts, and centers that had exceeded their goals recruited additional participants. As a result, 2,182 participants, or 104\% of the goal for recruitment, were randomized over a 13-month period. Those clinics using a cohort, or wave, type of enrollment were most successful in achieving their recruitment goals within the prescribed timetable.

  • The perilla leaf pyralid moth, Pyrausta panopealis Walker (Lepidoptera: Pyralidae), is a serious pest damaging to leaf perilla. In order to establish the life parameters of P. panopealis for eventual purpose of control, the developmental span of each stage was investigated under five temperature regimes ($20^{\circ}C{\sim}30^{\circ}C$). The larval period of P. panopealis was longest as 26.8 days at $20^{\circ}C$ and shortened as temperature goes up to $30^{\circ}C$ as 11.3 days. Survivorship of the larval P. panopealis was the highest at $27.5^{\circ}C$ as 82.5%, whereas that of other temperatures ranged from 40% ($20^{\circ}C$) to 60.0% ($30^{\circ}C$), indicating that the P. panopealis appears to favor somewhat higher temperature. In addition to larval period, the duration of egg, prepupal, and pupal period also were shortened sharply as temperature goes up, whereas the duration of adult stage shortened a maximum of only two days as temperature goes up. After the perilla leaf pyralid moths were successfully stabilized in indoor environment the larvicidal efficacy of ten on-the-market environmentfriendly agricultural materials (EFAMs) that were previously selected from the result of other moth species was tested. Seven of the ten tested showed more than 90% of mortality within 12 hrs and reached nearly up to 100% within 24 hrs, but the remaining three showed less than ~70%.

  • Rearing of tropical tasar silkworm, Antheraea mylitta Drury is mainly conducted in outdoor on Terminalia tomentosa W. & A. a nature grown primary host plant available in forest and also on raised primary host plant Terminalia arjuna Bedd. Temperature, relative humidity and rainfall are the main environmental factors for occurrence of pests (parasites and predators) of tasar silkworm during I, II and III crop rearing in the tropical tasar producing zones. The present study was aimed to study the influence of abiotic factors on prevalence of tasar silkworm pests. The study was conducted at different agro-climatic regions viz., Central Tasar Research &Training Institute, Ranchi, Jharkhand, Regional Extension Centre, Katghora, Chattisgarh and Regional Extension Centre, Hatgamaria during 2010-13 covering 3 seed crop and 6 commercial crops. Data on incidence of tropical tasar silkworm endo-parasitoids like Uzi Fly, Blepharipa zebina Walker and Ichneumon fly (Yellow Fly), Xathopimpla pedator, Fabricius and Predators such as Stink bug (Eocanthecona furcellata Wolf), Reduviid bug (Sycanus collaris Fabricius) and Wasp (Vespa orientalis Linnaeus) was recorded Weekly. The meteorological data was collected daily. Data was collected from 4 different agro-climatic zones of tasar growing areas. Analysis of the data revealed a significant negative correlation between abiotic factors and incidence of ichneumon fly and uzi fly. Based on the 3 years data on prevalence of pests region-wise pest calendars and prediction models were developed.

  • Sep gene, which is one of the cell division genes coding for penicillin binding protein 3 was subcloned from ${\lambda}607sep^{+2}$ to plasmid pBR322. which has a strong promotor such as lac UV5(lacP). It was confirmed that the sep gene cloned to pLJ3 was in the proper orientation for expressionfrom lactose promotor. To analyze the expression efficiency of sep gene within the plasmids newly constructed, sep mRNA was assated by using ${\lambda$\mid$\;607sep^{+2}$ DNA as a probe. Sep mRNA level was increased 25 times in the cells carrying sep gene cloned to pBR322 compared to E. coli C600 which has wild type sep gene within the chromosome instead of plasmed. Furthermore, the cells carrying sep gene cloned to pLJ3 derected the synthesis of about 50 times as much sep mRNA as did cells carrying sep gene cloned to pBR 322, representing that the sep gene was successfully cloned to pLJ3.

  • Guillain-Barre syndrome, or acute inflammatory demyelinating Polyradiculoneuropathy, is frequently accompanied by cardiac and autonomic dysfunction. We report a patient who had tachycardia, orthostatic hypotension, hypertension, pronounced blood pressure fluctuations, abnormal sweating, constipation and urinary frequency as well as qudriparesis. We thought that the GBS was incurred by Damp-Heat, used Heat-Clearing and Dampness-Transforming decoction(Chongjoo-tang) in the early stage. In the later stage, fortifying the Spleen and Boosting Qi plus Supplementing the Kidney decoction(Palmultang+chongawon) was used to remove low back pain and boost recovery. The patient reached the nadir 14 days after onset. He became bed-bound and autonomic dysfunction was very severe. From 3rd week, abnormalities of autonomic function and paresis impoved gradually and he could walk above 5m without walker or equivalent support at the 5th week after onset.

  • The endothelin (ET) signaling pathway controls many physiological processes in myocardium and often becomes upregulated in heart diseases. The aim of the present study was to investigate the effects of ET receptor upregulation on the contractile function of adult ventricular myocytes. Primary cultured adult rat ventricular myocytes were used as a model system of ET receptor overexpression in the heart. Endothelin receptor type A ($ET_A$) or type B ($ET_B$) was overexpressed by Adenoviral infection, and the twitch responses of infected ventricular myocytes were measured after ET-1 stimulation. Overexpression of $ET_A$ exaggerated positive inotropic effect (PIE) and diastolic shortening of ET-1, and induced a new twitch response including twitch broadening. On the contrary, overexpression of $ET_B$ increased PIE of ET-1, but did not affect other two twitch responses. Control myocytes expressing endogenous receptors showed a parallel increase in twitch amplitude and systolic $Ca^{2+}$ in response to ET-1. However, intracellular $Ca^{2+}$ did not change in proportion to the changes in contractility in myocytes overexpressing $ET_A$. Overexpression of $ET_A$ enhanced both systolic and diastolic contractility without parallel changes in $Ca^{2+}$. Differential regulation of this nature indicates that upregulation of $ET_A$ may contribute to diastolic myocardial dysfunction by selectively targeting myofilament proteins that regulate resting cell length, twitch duration and responsiveness to prevailing $Ca^{2+}$.

  • The purpose of this study is to identify factors influencing a health-promoting lifestyle among highly educated, married women with or without work outside the home. It is a direct interview, cross-sectional study. Subjects were 250 married, unemployed women and 236 married women employed as teachers. Women who have not graduated college, work only part-time or have no current spouse were excluded. The instruments used were the Health-Promoting Lifestyle Profile (Walker, et al., 1987) and the Habitual Physical Activity Questionnaire (Backe, et al., 1982), The HPLP scores of the employed, married women were significantly lower than those for unemployed respondents. for both groups of respondents, the self-actualization subscale was the highest score and the exercise subscale was the lowest score. The HPLP indicated that exercise is a very weak area. Thus, an increase in exercise time and frequency, especially for highly educated, married women, is suggested. Multiple regression analysis revealed that a health-promoting lifestyle of unemployed, married women was affected by sports activity, leisure-time activity, depression and satisfaction of role allotment. On the other hand, a health-promoting lifestyle of employed, married women was affected by sports activity, leisure-time activity, stress, self-perceived economic status, coffee consumption, husband's help, and maid's help. That is, with more sports activity and leisure-time activity, less depression and more satisfaction of role allotment, unemployed, married women would have higher HPLP scores. Also, with more sports activity and leisure-time activity, less stress, better self-perceived economic status, less coffee consumption, more husband's help and more maid's help, employed, married women would have higher HPLP scores. The results indicate that sports activity and leisure-time activity were the first and the second determinants of health-promoting lifestyle respectively. Therefore, an exercise-centered health-promoting program for highly educated, married women is suggested in the community or workplace. Especially, the program should be designed to be easily approachable for highly educated, employed married women who have more of a role burden compared to unemployed women.
