The aims of this study are to discover general aspects of the kinship behavior shown from singles and also the related variables that had influenced on the single's kinship behavior The research has based on a comprehensive survey with 78 men and 82 women who are single. Statistical methods, including frequencies, percentage, mean, standard deviation, t-test, F-test and Duncan Multiple Range test utilizing the SPSS for Windows 10.0, have been adopted for the analysis of the data compiled. The findings of this study were as follows: First, singles have shown the ordinary kinship behavior to their orientation families, those are parents, brothers and sisters. And they had more active kinship behaviors with parents than brothers and sisters. Second, variables such as pressure to marry, education level, job type, and parents' marital satisfaction, have influenced on the single's kinship behavior with parents. While income level have influenced on the single's kinship behavior with brothers, and age, income level, responsibility of care giving and reason for single, on the single's kinship behavior with sisters.

This paper is concerned with the active vibration control of beam equipped with piezoceramic sensors and actuators. The single-input and single-output positive position feedback controller is considered as an active vibration controller for the beam. The proposed single-input and single-output positive position feedback controller can cope with many modes of interest by summing each positive position feedback controller designed for each mode. In this paper, theoretical formulation is first explained in detail. We discuss how to design the single-input and single-output positive position feedback controller for a target structure by considering Euler-Bemoulli beam. It is found that the theories developed in this study are capable of predicting the control system characteristics and its performance.

Precise Point Positioning-Real Time Kinematic (PPP-RTK) is an improved PPP method that provides the user receiver with satellite code and phase bias correction information in addition to the satellite orbit and clock, thus enabling single-receiver ambiguity resolution. Single station PPP-RTK concept is special case of PPP-RTK in that corrections are computed, instead of a network, by only one single GNSS receiver. This study is performed to experimentally verify the positioning accuracy performance of single baseline RTK level by a user who utilizes correction for a single station PPP-RTK using dual frequencies. As an experimental result, the horizontal and vertical 95% accuracy was 2.2 cm, 4.4 cm, respectively, which verify the same performance as the single baseline RTK.

It is becoming more and more clear that each cell, even those of the same type, has a unique identity. This sophistication and the diversity of cell types in tissue are what are pushing the necessity for spatially distributed omics at the single-cell (SC) level. Single-cell chemical assessment, which also provides considerable insight into biological, clinical, pharmacodynamic, pathological, and toxicity studies, is crucial to the investigation of cellular omics (genomics, metabolomics, etc.). Mass spectrometry (MS) as a tool to image and profile single cells and subcellular organelles facilitates novel technical expertise for biochemical and biomedical research, such as assessing the intracellular distribution of drugs and the biochemical diversity of cellular populations. It has been illustrated that ambient mass spectrometry (AMS) is a valuable tool for the rapid, straightforward, and simple analysis of cellular and sub-cellular constituents and metabolites in their native state. This short review examines the advances in ambient mass spectrometry (AMS) and ambient mass spectrometry imaging (AMSI) on single-cell analysis that have been authored in recent years. The discussion also touches on typical single-cell AMS assessments and implementations.

Objective: The aim of this study was to introduce newly developed cooperation group standards of acupuncture needles for single use and to make a contribution to the future development of Korean Industrial Standards (KS) of acupuncture needles for single use. Results and Conclusion: Quality assurance and quality control with high safety profile is one of the most critical issues in medical device manufacturing. Up to now, proper attention has not been paid to this issue with respect to acupuncture needles for single use and their related devices. We, therefore, organized a committee to make guidelines to produce an acupuncture needle with high quality and safety. In the committee, we reviewed the topic from an historical viewpoint, and investigated the current situation of the standardization of acupuncture needles in other developed countries. Finally, we developed the cooperation group standards in advance of development of KS on the acupuncture needles for single use. The standards are composed of 12 sections describing: Scope, Normative references, Definitions, Materials, Configuration, Appearance and Cleanliness, Quality, Sterilization and Safety, Processing of Surface and Coating Material, Test, Packaging, and Labeling. We hope that the standards would be useful guidelines to produce high quality acupuncture needles and play an important role in the development of KS in the future.

Five strongest crimes against women has rapidly increased recently, and women' anxiety is also increasing. Especially, women who reside alone in houses show significantly high anxiety. Such social change is increasing necessity of applying CPTED to housing environment of a single woman household. However, there have been less than enough number of researches on application on CPTED to housing environment of single woman household. So, this study would like to suggest housing environment of single woman household through CPTED guideline. With respect to research method, this study surveyed single woman households in their twenties and thirties who reside at single houses in Gwanak Gu, Gangnam Gu, Songpa Gu, and Mapo Gu in Seoul about necessity of CPTED guideline. Based on the survey results, this study conducted frequency analysis and descriptive statistics; and conducted independent sample t-test, one-way ANOVA, and Scheffe's posteriori test, according to demographic characteristics. As a result, differences in the contents of CPTED guideline by the demographic characteristics turned out to be small, generally. Thus, I concluded that suggestion for housing environment according to characteristics is not necessary. Instead, I would suggest contents of CPTED guideline that gained more than 4 points for housing environment. Research results of this study are as follow. First, 'Securing view of inside and outside of the house and controlling access' should be applied to housing environment of single woman households in their twenties and thirties residing in single houses in Seoul. Second, 'Securing view of an alley and improving walking space' should be applied. Third, 'installing CCTV and emergency bell' should be applied. Fourth, 'reinforcing territoriality of space' should be applied.

A series of experiments were designed to determine the feasibility of single dose of FSH as an effective superovulation method in rabbits. The superovulation treatments examined comparatively were as follows: 1) a single injection of 100 IU PMSG, 2) Multiple injections of 1 IU Super-OV of 2X daily for 3 days, 3) Multiple injections of 6.6 rng Folltropin-V 2X daily for 3 days, 4) Multiple injections of 13.3 rng Folltropn-V l$\times$ daily for 3 days, 5) Single injection of 40 mg Folltropin-V solved in 10% PVP, and 6) Single injection of 40 mg Folltropin-V dissolved in 25% PVP. The results obtained were as follows: The nurnher of ovulation points in the single injection of 40 mg Folltropin-V dissolved in 25% PVP and multiple injections of 6.6 mg Folltropin-V 2X daily for 3 days was averaged 44.6 and 39.2, respectively, which were significantly (P<0.05) more than in a single dose of PMSG or multiple doses of Super-OV. The number of total ova recovered in the single injection of 40 mg Folltropin-V dissolved in 25% PVP and multiple injections of 6.6 mg Folltropin-V 2X daily for 3 days was averaged 30.4 and 25.9, respectively, which were significantly (P<0.05) more than in the single dose of PMSG or multiple doses of Super-OV. A similar result was obtained for the number of fertilized ova recovered from the above six treatments. From the above results it was concluded that a single injection of 40 mg Folltropin-V dissolved in 25% PVP could be an effective and simple method for superovulation in rabbits.

This study investigates the effect of diesel combustion strategies on exhaust emissions and hydrocarbon species emissions for a 1.7 L common rail direct injection diesel engine at 1500 rpm and 3.9 bar BMEP. The first strategy is a method to adopt no EGR with a split injection composed of pilot and main injection (split injection). The second is to adopt a moderate EGR rate with main injection only (single-1). The third is to use a high level of EGR and main injection with rail pressure increase, $i.e.$ low-temperature diesel combustion (single-2). Split injection and single-1 showed a renowned phenomenon of a PM-NOx trade-off, whereas single-2 was observed of a PM-NOx trade-off to reduce PM and NOx simultaneously. HC speciation results show that the split injection produced the least amount of HC species, regardless of the carbon number bin, followed by single-1 and single-2. The ratios of methane, acetylene, and CO to THC increased as a combustion A/F ratio is richer due to reduced oxygen content in the vicinity of the combustion zone, thus enhancing pyrolysis.

Calving records of Holstein dairy cows from 2005 to 2010 comprising Goyang and Paju cities herd with 2,362 calving events representing 240 twin births were used to evaluate the effect of abomasal displacement and retained placenta after single or twin births on fertility. In retained placenta cows, the period of twin pregnancy (mean 270.5 days) was shorter than that of single pregnancy (mean 274.8 days), however first artificial insemination period (twin: mean 107.4 days, single: mean 92.0 days), non-pregnant period (twin: 154.8 days, single: 132.2 days), and number of insemination (twin: mean 2.00 times, single: mean 1.87 times) of twin pregnancy were increased as compared with single pregnancy. In abomasal displacement cows, first artificial insemination period (twin: mean 122.9 days, single: mean 106.0 days), non-pregnant period (twin: 172.4 days, single: 152.0 days), and number of insemination (twin: mean 2.16 times, single: mean 1.89 times) of twin pregnancy were increased as compared with single pregnancy. The prevalence of complication such as retained placenta, abomasal displacement with single or twin births increased first artificial insemination period, non-pregnant period, and number of insemination period.
