Traditional concurrency control strategies for database system are inappropriate for mobile computing environments in which communication disconnection could occur frequently. The time available to access transactions may be extremely limited in mobile computing. In order to ensure that this time is utilized most effectively, the short-lived transactions must be a main stream of transactions. Service handoffs which occur due to communication disconnection, could degrade the performance of mobile transactions especially for short-lived transactions. Altruistic locking protocol is in its nature favorable to short-lived transactions since it applies the donation of locks to long-lived transactions as early as possible. Performance for short-lived transactions could be improved when we applied altruistic locking to mobile computing.

Recently, with the development of interactive communication system, demands for video live streaming service has increased. Live streamers generate revenues from donations, but existing laws are inadequate to handle these donations. Problems arise when minors donate because they have the right of revocation. In the case of donations that request benefits in return, legal characteristics and results are different from unilateral donations. If minors exercise their right of revocation, live streamers must pay back without getting proper compensation for their services. In this paper, we detect the characteristics of bilateral contract in live streaming donation, indicate the harms that live streamers can get, examine precedents and donation processes focusing on cases when minors can not exercise the right of revocation due to deception, and propose revisions that can protect the streamers without invading minors' rights. Through academically identifying ambiguous legal situations and presenting dispute prevention procedures, this paper can bring positive impacts on the online industry.

The purpose of this study was to present basic data in the nursing practice for the management of living kidney donor by understanding the nature and meaning of kidney donors, experiences. The research subjects were 11 living kidney donors who had donated from Mar 1991 to Feb. 1994 and discharged from the 3 hospitals in Pusan. Data has been collected by Intensive interview with donors. The data analysis has made by phenomenological method of Van Kaam for understanding the phenomenon and meaning of their experiences. The experiences of kidney donors were analyzed into the 4 situations, that is,'motivation of kidney donor', 'decision time to make kidney donation', 'pre-opperation','after donation'. The descriptive expression and common elements were drawn from original data of each situation on the basis of subjects' own words. From each situation, the com-mon elements of kidney donors' experiences were integrated, summarized and described as follows 1. Motivation of kidney donation They wanted to donate their kidney because of empathy of pain on the groung of love to the recipient and with exppectation of successful kidney transplant or as a solution of economic difficulty. 2. Experiences in deciding to make kidney do-nation In deciding to make kidney donation, donors had love toward the recipients. But they experienced conflict too. 3. Experiences before being operated on donated kidney In experiences from deciding to make kidney do nation to preoperation, donors had love toward the recipients. But they also felt anxiety or dissatisfaction. Therefore, they controlled their mind by their faith, support of medical staff or support of society. And they experienced regret for the sociological cognition or financial apprehension. 4. Experiences after kidney donation After kidney donation, donors experienced satis-faction and accompplishment in spite of mental and physical discomfortness, while they felt sense of loss / disappointment, repentance, regret, and apprehension of progress toward their condition. Thus, kidney donors donated their kidney on the ground of empathy and love to the recipient and with expectation of successful kidney transplant. But during the process of kidney donation, they ex perienced conflict, love, anxiety, regret, apprehension of economy. And after donation, they felt sense of satisfaction and accomplishment, while they felt sense of discomfortness, loss / disappointment, re-gret, repentance, or apprehension of progress toward their condition. This result contribute to nurses' role not only for the management of living kidney donors but also for the management of cadaver donors' family.

A way to increase effectiveness of charitable donation ads is to activate or magnify emotional experiences (e.g., sympathy, empathy, psychological distress) among target audience. Past studies suggest that mental imagery and attention, which activate or magnify emotional experiences, can be influenced by verbal message attributes (i.e., message concreteness and valence) of charitable donation advertisements. Based on the previous research, the study built a conceptual framework for processing of charitable donation advertising: message concreteness and valence ${\rightarrow}$ mental imagery and attention ${\rightarrow}$ emotional experiences ${\rightarrow}$ donation intention. To verify the framework, the study investigated on the influence of message concreteness and valence on mental imagery and attention through assessing ERP responses. It also examined how message concreteness and valence have an effect on the intent to donate through measuring the amount of donation. The study revealed that concrete message activated mental imagery more than abstract message whereas negative message enhanced attentional level more than positive message. Compared to the other conditions, when the message was concrete and negative, the amount of donation was significantly large.

This study examined the importance of social contribution through the existing research data on social contribution and the progress of social contribution activities of public institutions in Wonju Innovation City. The social contribution activities of nine organizations out of 14 public institutions were analyzed in detail and suggested the right direction of social contribution activities of public institutions based on this analysis. First, recent trends are being developed to cooperate with local communities through public interest activities rather than simple donations or sponsored forms of social contribution. Second, the synergy effect was maximized by systematically approaching local communities rather than a one-time, one-off social contribution. Third, it should contribute to the revitalization of the local economy in the mid- and long-term by creating a social economy in cooperation with local civil society rather than a one-sided social contribution.

It is a tentative study on the influence of the consumers' motivation of charity impulse on their loyalty who donate to non-profit organizations. Based on the self-determination theory, this thesis paper analyzed the motivation of charity impulse on non-profit organizations which is the main factor influencing the donation loyalty with consumer-nonprofit identification as parametric variables. According to this study, it seems that the charity impulse caused by the concepts of autonomy of the self-determination theory has negative influence on consumer-nonprofit identification, donation loyalty. But relation-competence has positive influence to nonprofit organizations. Considering without any studies on donators' motivation of charity impulse from the aspect of psychology to non-profit organizations, as the very initial exploratory study, this study is conducted to analyze the possible factors to influence customers' motivation of chanty impulse on the basis of the self-determination theory so that it has a vital significance, which can furnish fundamental data to charitable organizations to carry out effective marketing strategies to guarantee the source of the money collection.

Free radicals formed during the metabolism of environmental chemicals are known to induce mutagenicity, while different types of antioxidants suppress this event. The purpose of this study was to determine the antioxidative and antimutagenic effects of soybean saponins, and to examine the relationship between these two effects for the elucidation of mechanisms involved in the anticarcinogenicity of soybean saponins. Also, antioxidative and antimutagenic effects of soybean saponins were compared with those of kinown antioxidants. For the measurement of antioxidative capacity, soybean saponins, L-ascorbic acid, $\alpha$-tocophoerol, and BHT at concentrations between 005 and 1.0mg/ml were tested for their ability to donate hydrogens and to reduce the formation of thiobarbituric substances(TBARS). Antimutagenic activity was examined using the Ames salmonella test system at concentrations of 600, 900 or 1200ug/ml. Study results showed soybean saponins and all of the other antioxidants tested possessed dose-dependent antioxidative activities. The ability of hydrogen-donation to DPPH was in the order of L-ascorbic acid>$\alpha$-tocopherol=>BHT>soybean saponins. TBARS formation was also inhibited by these compounds, in the order of BHT>$\alpha$-tocopherol=L-ascorbic acid>soybean saponins. Soybean saponins and other antioxidants also showed antimutagenicity in a dose-dependent manner. Especially, soybean saponins and BHT were excellent antioxidants compounds, inhibiting near 80% of the mutagenic effects at a concentration of 1200ug/ml. The correlation coefficients between antioxidative capacity and antimutagenicity for each compund was statistically significant at p<0.05. These results indicate that soybean saponins possess antioxidative and antimutagenic capacities. Also, antimutagenicity of saponins and other antioxidats is partly due to their antioxidative activities.

Taurine is known to suppress oxidant-induced tissue injury by stabilizing biomembrane and scavanging free radicals. The purpose of this study was to determne the antioxidative and antimutabenic acitvities of taurine, ad to compare those acitivities with major antioxidants. For the measurement of antioxidative capacity, 0.05 , 0.1,0.5 and 1.0mg/ml of taurine, L-Ascorbic acid, alpha-tocopherol, and BHT (dibuty hydroxiy toluene)were prepared and tested for their ability to donate electrons to DPPH (1,1-diphenyl-2-picryl-hydrazyl). Antimutagenic acitivity was examined using the Ames salmonela test system at concentrations of 600, 900 and 1200ug/ml. Results indicated that taurine possesses electron-donating capacity, however, the degree of donation was very weak compared to the major antioxidants tested. However, taurine was evaluated as a potent mutation suppressor. Antimutagenic capacity was in increasing order BHT>taurine>L-ascorbic acid>alpha-tocopherol at concentrations of 600 and 900ug/ml. There was a dose-dependent increase in antimutabenicity of these compounds , however, antimutagenity of the 900ug taurie/plate was not significantly differently from that of 1200ug taurine/plate. These results indicate that taurine effectively suppresses the mutagenicity of AFB1 without noticeable elelctron donating ability.

Purpose: This study was done to Identify attitude and factors influencing attitudes to organ transplants. Method: Study participants were 165 people over the age of 18 and living in Seoul. The instrument used for this study was the descriptive questionnaire developed by Ju (1995). Analysis of the data was done with SPSS Win 10.0 with descriptive statistics. t-test. ANOVA and stepwise multiple regression. Results : 1. The scores on attitude toward organ transplants ranged from 14 to 70. and had a mean score of 49.26. There were statistically significant differences in scores on attitude to organ transplants according to age (p= .03). marital status (p= 00), monthly income (p=.02) and experience of having education about organ transplants (p= .00). 2. The factors influencing attitudes to organ transplants were having the experience of education on transplants and marital status. These two variables explained 20.1% of the variance. 3. Reasons given for no written pledge to donate one's organs were 'fear on organ donation', 'not knowing the way of' how to do'. 'plan to give my organs to a family member when needed'. 'physical condition' and 'religious belief'. Conclusion: Experience with education for organ transplant and marital status were identified as important variables in attitudes to organ transplants.
