  • Winter cereals are acclimated during wintering, and thereafter their freezing resistance is increased. In order to analyze inheritance and heritabilities for photoinhibition of photosynthesis by high light intensity under low temperature, and to evaluate the relationship between low temperature-induced photoinhibition and winter survival, 4 parental half diallel crosses were used. The detached leaves of 7-8cm long from plants grown for 35 and 55 days were placed on wet filter paper and placed in trays at 5$^{\circ}C$ cold room with 1,200 $\mu$mol $m^{-2}$ $s^{-1}$ PPFD. Chlorophyll fluorescence was measured with a chlorophyll fluorescence system after dark adaptation for 30 min. The Fv/Fm of 35day old plants was reduced from 0.714 in the control leaves to 0.409 and 0.368 following photoinhibitory treatment of 6h and 8h and the CVs were increased from 0.8% to 22.2-22.3%. The Fv/Fm of 55-day old plants was reduced from 0.775 in the control leaves to 0.485 and 0.439 following photoinhibitory treatment of 10h and 12h, respectively. According to half diallel cross analysis, Reno and Dongbori 1 (highly resistant to photoinhibition) was dominant, but Oweolbori (susceptible to photoinhibition) was recessive, and photoinhibition showed partial dominance with highly additive gene action. Dongbori 1 showed the greatest GCA effects for photoinhibition, and GCA/SCA ratios (8.7-22.3 times) indicated that the additive variance for the character was more important. Winter survival in barley crosses was positively correlated with resistance to photoinhibition and significantly fitted by linear regression ($R^2$=0.751$^{**}$-0.779$^{**}$). The chlorophyll fluorescence measured by Fv/Fm has been found to be highly inheritable and very useful in evaluating relative levels of freezing resistance in barley.ley.

  • Casual games are often have simple rule and easy to play. Like Angry birds, players can sling a bird as a bomb to destroy target. But the film adaption encounters numerous questions. games in pursuit of strong sensed presence, pay attention to experience; film stress the integrity of the story, attaches great importance to plot. However, casual games don't have story and plot. This paper take angry birds as example, analyzes the difficulties and method of adaptation from leisure mobile games to films, summarizes the key successful elements of adaption, such as subdivided the target group, chose an appropriate genre, write a script follow the basic logic and frame of film, set contradiction, complicated the character and still contain key elements of the game, in order to provide new ideas in the future development of integration of game and movie industry.

  • Gender role identity is a key subject toward adaptation in later life. In this paper, we tried to understand the specific types and characteristics of gender role identity in view of older men. The research collected and examined 40 representative descriptions representing gender role identity, including 20 for masculinity and 20 for femininity from 40 older men. We obtained four types of gender role identity of older men from this research. "Powerful-expressive type" is energetic and reveals his brave and dominant tendency when they are working. "Powerful-taciturn type" is strongly independent and has a firm conviction, but they do not express those characters and remain silent. "Powerful-paternal type" handles his work with a driving force, and has a tender character. "Paternal-caring type" finds his own worth in life by caring for his family and children, and considers others more than himself. Future research is needed to verify how the types of gender role identity are linked to psychosocial adaptive aspects, health behaviors, mental and physical health.

  • This study was conducted to understand the degree of personality and interpersonal relationships among dental hygiene students. The survey was conducted from April 1, 2021 to June 30, 2021. As a result of the study, personality was 3.42 points and interpersonal relationships were 3.46 points. In general, there was a statistically significant difference in both personality and interpersonal subdomains in interpersonal satisfaction and college life satisfaction (p<.05, p<.001). The more experience they had in clinical practice, the lower their scores for friendship and professorship among interpersonal relationships. Among the sub-domains of personality, morality and sociality were analyzed as having the highest positive correlation (r=.674), and in interpersonal relationships, the relationship between friends and professors was analyzed as high (r=.606). Therefore, for the holistic growth of dental hygiene students as preliminary dental hygienists and their adaptation to the dental care field, a long-term strategy and continuous educational approach are needed at the university for cultivating character and interpersonal relationships, which are the basics. In addition, various programs related to the duties of dental hygienists should be developed and methods to be applied should be sought.

  • The present paper focuses on a specific aspect of H. G. Wells' The Island of Doctor Moreau (1896), namely the issue of homosexuality, particularly as it concerns Prendick, the novel's primary narrator, and Montgomery, Moreau's assistant on the island, both of whom are implicitly associated with homosexual identity-and suggested to represent various forms of repression or acceptance-their personalities, or psyche, explored in relation to other characters on Moreau's island, particularly the Beast Folk, as well as Doctor Moreau and his treatment of the creatures as an allegory of Victorian anti-sodomy legislation and its most celebrated victim, Oscar Wilde, who had been convicted for male sodomy in 1895, only months prior to the original publication of The Island of Doctor Moreau. In addition, this paper examines an extensive series of allusions to Oscar Wilde and to late-Victorian homosexual scandals, including that author's own conviction, allusions to others involved in the affair-some of which involve situational/plot analogies, while others involve echoes or semantic associations between the names of characters in Moreau and historical figures-as well as allusions and parallels involving the most recognizably biographical of Wilde's works, The Picture of Dorian Gray (1890). The deliberate, complex web of allusions and ironic implications of homosexuality, presented in this essay, thus, expands considerably upon existing scholarly work on a range of matters concerning homosexual identity and conduct within the context of social conventions and legislation in the late-Victorian period, as well as more broadly, in scientific and humanistic terms. In this respect, one key aspect of this essay is the exploration of the novel's setting of Noble's Island, which, among other things, includes topographical allusions to nineteenth-century scientific theories of anatomical anomalies in pederasts-namely those of the eminent French forensic medical scientist, Ambroise Tardieu (1818-1879), whose underlying framework of physiological adaptation, moreover, intersected with the scientific interests of Wells and of his protagonist. Beyond this, it is shown that, in Moreau, there is as a web of allusions to homosexual practice and those same anomalies, involving the character of Montgomery and his name.

  • An experiment was conducted at the greenhouse of the International Rice Research Institute in 1987 to find out the character of dry matter production, the potential seed production ability and the ecological and physiological strategies to adaptation. For these, two rice cultivars, IR64(lowland rice) and UPLRi-5(upland rice), and seven weed species were used ; Echinochloa glabrescens Munro ex Hook. f., E. cress-galls ssp. hispidula (Retz.) Honda, E. colons (L.) Link, Monochoria vaginalis (Burin. f.), Ludwigia octovalvis Jacq.) Raven, Fimbristylis miliacea Vahl and Cyperus difformis L. Adaptation strategies of weed species varied by species. However, they had efficient seed production strategy through different ways. In general, sedge weed species (F. miliacea and C. difformis) produced great amount of seeds at the expense of seed size through greater ratooning ability and low relative dry weight for flowering. For broadleaved weed species, greater number of descendants were obtained through high plasticity and low relative dry weight for flowering (M. vaginalis) or greater growth ability through effective photosynthetic efficiency (L. octovalvis). Grass weed species, on the other hand, produced their seeds through effective growth (net assimilation rate and relative growth rate), high ratooning ability (except E. crus-galls ssp. hispidula) or low relative dry weight to maximum dry weight for flowering (E. glabrescens). The harvest indices of the weed species were considerably lower than those of rice. Fimbristylis miliacea had the greatest ratooning ability followed by C. difformis, E. colons and E. glabrescens. The greatest seed productivity was recorded by C. difformis (279, 000) and L. octovalvis (268,000) while rice produced the least number of seeds (1300-6100). Log seed weight had a negative linear relationship with log seed number (y=6.30-1.48X, $R=-0.965^{**}$). For all species plant plasticity response was not directly correlated with mortality response.

  • The purpose of this study was to review articles and theses on adjustment of college freshmen from domestic researches conducted during the past 11 years, to identify overall research trends, and to suggest direction and strategies for college freshman's adjustment. The final 24 articles were selected from three databases, RISS, KISS, and NAL (National assembly library) using specific inclusion criteria. Twenty were correlation studies and four were experimental studies. In 2009, the first study on adjustment of college freshmen was published. Since then several more studies have been conducted to date. This means that people have recognized the importance of adjustment of college freshmen. Twenty three studies that are reviewed used Baker and Siryk's college adjustment tool. From reviewed correlation studies, mean score of college students' adjustment was 3.25. The related variables with adjustment of college freshmen revealed 20 items, especially self-esteem, self-efficacy, and stress showed important related concepts. The general characteristics related to adjustment of freshmen were outgoing character, living with family, aged students, satisfied with the area of study, and satisfied with school life. The findings of this study indicated that colleges when planning for the freshmen orientation program should focus on improving self-efficacy of students, stress management, mentor program, and freshmen adjustment program for each department of the school and college.

  • The genetic structures at one leucine aminopeptidase locus (LAP-A) of acorns, seedling raised in greenhouse and forest form the two beech provenances. West Germany and Rumania, were investigated and compared with each other. In many pair wise comparisons significant differences in genotypic structure as well as genic structure were ascertained between different developmental stages. In both the provenances, the allele $A_2$ seems to have advantage at both seedling stages raised under two different conditions. Homozygous carriers of $A_2$ allele survived best in greenhouse, while heterozygous carriers especially with $A_2$ allele possessed great viability under more variable environmental conditions. Since a distinct different genetic background was present in two base populations, the identical effect of the allele $A_2$ confirms the adaptiveness of this locus. With aid of some measures such as viability parameter and genetic distance, the character of occurred viability selection of further explained. The possible significance of this locus at this early stage is discussed in relation to adaptation of this long lived tree species to heterogeneous environment.

  • Today, more chronically ill and handicapped children are being cared for at home by a family member caregiver. The task of caring for a family member may feel burden that the caregiver has less time and money and more work. Family functioning and their burden have influence on coping and adaptation of families with chronically-ill children. This study attempted to identify the levels of burden and family functioning in families of children with cerebral palsy and to examine their relationships. The instruments were burden scale developed by Suh and Oh(1993), and a modified Feetham Family Functioning Survey based on Roberts and Feetham.(1982). The subjects were 98 parents of children, under 15 years, who have cerebral palsy and being treated and living in Pusan. Data were collected through a self-administered question- aire from April 26 to May 29. The collected data were tested using frequencies, percentiles, means, t-test, ANOVA, and Pearson correlation coefficient with SPSSWIN program. The results of this study were as follows ; 1. The mean rating scores of burden and family functioning were 2.79±.51 and 4.12±.69, respectively. 2. The relationships between general character- istics and burden were statistically significant difference : degree of children's handicap(F=6.333, P<.01). The relationships between general characteristics and family functioning were statistically significant differences : familial relation with the children(F=3.628, P<.05), caregiver's health status(F=4.359, P<.05), age of children (F=4.185, P<.05), and duration of treatment (F=6.802, P<.01). 3. In families of children with cerebral palsy, there was significantly negative correlation between the burden of parents and the performance of family functioning(r=-.230, P<.05). There were significantly negative correlations between the burden of parents and the satisfaction of family functioning (r=-.211, P<.05), and between the perceived importance and the satisfaction of family functioning(r=-.481, P<.01); however, there was a positive correlation between the performance and the perceived importance of family functioning(r=.425, P<.01). In conclusion, this study suggests that families of children with cerebral palsy need family-focused nursing interventions as supportive care for relieving their burden and for improving family functioning.

  • The Chrysanthemum zawadskii complex is demarcated from other species by having the white and pink ligulate flowers. Its morphological characters are greatly diversified, so that various classification systems have been suggested. The character of leaf thickness has been mentioned as the characteristic for recognizing some of infra-specific taxa within this complex. In this study, we used longitudinal leaf sections to investigate the leaf thickness and cell number of leaf blades of 13 populations including those of the members of the C. zawadskii complex, as well as 4 populations of the related species of C. boreale and C. indicum. From the result, it was clear that the leaves were thicker in populations of C. boreale, C. indicum and C. zawadskii complex (diminishing in that order), and that the leaves were composed of about 9 cell layers in all populations. Within the C. zawadskii complex, leaf shape and thickness varied among the populations. It was very interesting that the taxa with restricted distribution, like C. zawadskii var. tenuisectum, C. zawadskii var. alpinum, C. zawadskii var. lucidum, and C. zawadskii subsp. coreanum had a thicker leaves than found among widely occurring taxa. From this, leaf thickness is supposed to be an adaptation to the unique habitat of each population.
