Background/Aims: Data on the incidence of adverse respiratory events during recovery from gastrointestinal endoscopy are limited. The aim of this study was to investigate the incidence of these complications. Methods: In this retrospective cohort study, data were obtained from the electronic records of 657 consecutive patients, who underwent gastroenterological procedures under sedation. Results: Pulse oximetry oxygen saturation (SpO2) <90% for <60 seconds occurred in 82 patients (12.5%), and in 11 patients (1.7%), SpO2 of <90% for >60 seconds occurred in 79 patients (12.0%) and in 14 patients (2.1%), and SpO2 <75% occurred in four patients (0.6%) and in no patients during the procedure and recovery period, respectively. No major complications were noted. The occurrence of desaturation during recovery was correlated with desaturation during the procedure (p<0.001). Higher American Society of Anesthesiologists score (odds ratio [OR], 1.867; 95% confidence interval [CI], 1.008–3.458), ischemic heart disease (OR, 1.815; 95% CI, 0.649–5.080), hypertension (OR, 1.289; 95% CI, 0.472–3.516), and diabetes mellitus (OR, 2.406; 95% CI, 0.950–6.095) increased the occurrence of desaturation during recovery. Conclusions: We found no major complications during recovery after balanced propofol-based sedation administered by a gastroenterologist-nurse team. Patients with the identified risk predictors must be monitored carefully.

Determinants of Forgiveness in Families

Inna Reddy Edara,Jo-Lin Chen 가톨릭대학교(성심교정) 인간학연구소 2018 인간연구 Vol.0 No.37

This quantitative research investigated the determinants of forgiveness of a family transgressor by the offended. Data from 431 college students were analyzed to investigate the nature and frequency of the offenses, specific relationship of the offended with the transgressor, severity of the hurt, role of relationship variables, positive dispositional tendencies, and hurt intensity in the forgiveness of the family member. The analyses indicated that some of the most occurring offenses were being ignored, not fulfilling promises, being compared with others, and unequal distribution of household tasks. Participants indicated being compared with others as the most serious offense, followed by contempt, not fulfilling promises, and being ignored. Due to these offenses, about 59% of the participants experienced moderate to above the average severity of hurt. Hierarchical multiple regression analyses suggested that the positive dispositional tendencies of optimism and resilience explained 14% of incremental variance in forgiveness. In the third step of the regression, relationship variables of trust, communication, and alienation together explained an additional 28% of the variance, above and beyond gender and dispositional tendencies. In the final step, hurt severity was a significant predictor, explaining an additional 5% of variance in forgiveness. These significant results suggest that after controlling for both demographic variables and dispositional traits, the close relationship variables along with the severity of the hurt experienced by the victim in the context of family relationships play a significant role in the forgiveness of the family offender.

Objective: To compare our in-house method of embryo freezing with Cryotop vitrification in terms of immediate survival, subsequent cleavage and blastocyst formation, and cell numbers in blastocysts. Methods: Two-cell mouse embryos were randomly allocated into three groups: a non-frozen control group (group 1, n = 300), a group that underwent Cryotop vitrification (group 2, n = 300), and a group that underwent our in-house freezing method (group 3, n = 300). Results: There were no significant differences between groups 2 and 3 in the immediate survival rate (96.3% vs. 98.6%, respectively; p= 0.085), the further cleavage rate (91.7% vs. 95.0%, respectively; p= 0.099), or the blastocyst formation rate (80.7% vs. 78.6%, respectively; p= 0.437). The cell numbers in the blastocysts from groups 1, 2, and 3 were comparable ($88.99{\pm}10.44$, $88.29{\pm}14.79$, and $86.42{\pm}15.23$, respectively; p= 0.228). However, the percentage of good-quality blastocysts in the Cryotop vitrification group was significantly higher than in the group in which our in-house method was performed, but was lower than in the control group (58.0%, 37.0%, and 82.7%, respectively; p< 0.001). Conclusion: At present, our method is inferior to the commercial Cryotop vitrification system. However, with further improvements, it has the potential to be useful in routine practice, as it is easier to perform than the current vitrification system.

Three-machine Open Shop Problem with the Minimum Makespan Criterion

Inna Drobouchevitch 한국생산관리학회 2016 韓國生産管理學會誌 Vol.27 No.1

The paper considers the three-machine open shop scheduling problem to minimize the makespan, i.e., the maximum completion time (O3||Cmax). The open shop problem was introduced by Gonzalez and Sahni who gave a polynomial time algorithm for its solution in the case of two machines. They also proved that this problem is NP-hard in the case of three machines. In view of the problem complexity, it is an attractive research goal to search for the widest possible classes of problem instances which admit efficient solutions. Such problem classes can be formulated in terms of a certain relation between machine loads and maximum operation length. Let Li be the load (the total time of all operations) of the ith machine and let pmax be the maximum operation length. Suppose that the machines are numbered in the non-increasing order of their loads. The O3||Cmax problem is known to be polynomially solvable if L1-L3≥2pmax. In this paper, we show that the problem is ordinary NP-hard if 2L1-L2-L3< 2pmax. We then consider a special case of the O3||Cmax problem that lies outside the known NP-hardness bounds and show that it is solvable in linear time.

On the problem of movie selection and scheduling to maximize revenue

( Inna G. Drobouchevitch ) 한국생산성학회 2015 生産性論集 Vol.29 No.4

We consider a problem of the selection and scheduling of movies for a multiplex (i.e., a theater with multiple screens) to maximize the exhibitor``s cumulative revenue over a fixed planning horizon. Effective and timely decisions on screen management directly and crucially relate to the effective capacity and resources usage, productivity and successful economical performance of the theater. In the problem under study, the release times of the movies that can potentially be selected during the planning horizon are known a priori. If selected for screening, a movie must be played continuously through its obligatory duration, after which its run may or may not be extended. The problem involves two primary decisions: (i) the selection of movies to play and (ii) the determination of the duration of screening for the selected movies. We show that revenue optimization problem under the preempt-resume policy is strongly NP-hard even in the minimal case, thus completely resolving the complexity status of the problem. We also consider the optimization problem under the non-preempt policy for a case of unequal screen capacities and show that an optimal solution may significantly differ from the solution obtained for the equal-capacity case.

Species Composition and Seasonal Dynamics of the Population Density and Biomass of the Genus Pyramimonas (Prasinophyceae) from the Russian Waters of East/Japan Sea

Inna Valentinovna Stonik 한국해양과학기술원 2009 Ocean science journal Vol.44 No.1

The species composition and seasonal dynamics of the population density and biomass of the prasinophycean algae of the genus Pyramimonas were investigated in the Russian waters of the East/Japan Sea. According to literature data and the results of our observations, eight species of the prasinophycean algae were identified, and some of them were new for the Russian waters of the East/Japan Sea as follows: P. aff. amylifera Ñonrad, P. aff. cordata McFadden, Hill et Wetherbee, and P. nansenii Braarud. An analysis of their seasonal dynamics showed that the most conspicuous winter peak of the population density of Pyramimonas species in the Amurskii Bay was clearly distinguishable in February. In winter and early spring, the prasinophycean algae made a considerable contribution of 28 to 60% into the total population density on the background of a relatively low biomass, 1.1-14.4% of the total phytoplankton biomass in the Amurskii Bay. In the Golden Horn Bay, the summer peak of the population density of Pyramimonas species was most intensive in June. In summer, during the period of mass development of the algae of the genus Pyramimonas in the Golden Horn Bay, the prasinophycean algae contributed up to 71% of the total population density and up to 84% of the total microalgal biomass. An increase was noted in the density and biomass of the Pyramimonas species in the polluted waters near the sewage water outlets in the Amurskii and Golden Horn bays.
