This study is a follow-up study of Kang and Kim (2020). In this study, we derive the sample influence functions of the t-statistic which were not directly derived in previous researches. Throughout these results, we both mathematically examine the relationship between the empirical influence function and the sample influence function, and consider a method to approximate the sample influence function by the empirical influence function. Also, the validity of the relationship between an approximated sample influence function and the empirical influence function is verified by a simulation of a random sample of size 300 from normal distribution. As a result of the simulation, the relationship between the sample influence function which is derived from the t-statistic and the empirical influence function, and the method of approximating the sample influence function through the empirical influence function were verified. This research has significance in proposing both a method which reduces errors in approximation of the empirical influence function and an effective and practical method that evolves from previous research which approximates the sample influence function directly through the empirical influence function by constant revision.

We tested the difference and the relationship in instructional ratings by professors and college students. Subjects were 6 professors and 9 college students participated in teaching competition as a rater. They completed instructional rating forms consisted of 10 criteria for 11 participants according to Lickert Scale. Data were analyzed by independent t-test and Pearson correlation. Results were as follows: ① There was no statistical difference in mean scores between the professor and the student; ② Correlation between professors' and students' evaluations was .78 which is statistically meaningful and high. These results support the notion that students evaluate as reliably as professors. They also imply that pre-service college students can be utilized for teaching practice as meaningful peer evaluators. The findings are meaningful in that instructional ratings of instructors and students were compared in a controlled setting. However, replication studies involving wide range of instructors and students are needed for generalization since the subjects in this study were restricted to pre-service teachers and their instructors.

In this study, we measured the inhibitory activity of Pinus densiflora leaf (PDL) against excessive lipid accumulation in mouse preadipocyte, 3T3-L1 cells to investigate whether PDL exerts anti-obesity activity. Lipid accumulation and the protein level were measured using Oil red O staining assay and Western blot analysis, respectively. We observed that PDL inhibited excessive lipid accumulation and decreased the expression of CEBPα, PPARγ and perilipin-1 related to lipid accumulation in 3T3-L1 cells. Therefore, considering these results, PDL can be used as a potential agent for anti-obesity.

Internet of Things (IoT) technology, which provides services by connecting various objects in the real world and objects in the virtual world based on the Internet, is emerging as a technology that enables a hyper-connected society in the era of the 4th industrial revolution. Since IoT technology is a convergence technology that encompasses devices, networks, platforms, and services, various studies are being conducted. Among these studies, studies on measures that can measure service quality provided by IoT software are still insufficient. IoT software has hardware parts of the Internet of Things, technologies based on them, features of embedded software, and network features. These features are used as elements defining IoT software quality measurement metrics. However, these features are considered in the metrics related to IoT software quality measurement so far. Therefore, this paper presents a metric for reusability measurement among various quality factors of IoT software in consideration of these factors. In particular, since IoT software is used through IoT devices, services in IoT software must be designed to be changed, replaced, or expanded, and metrics that can measure this are very necessary. In this paper, we propose three metrics: changeability, replaceability, and scalability that can measure and evaluate the reusability of IoT software services were presented, and the metrics presented through case studies were verified. It is expected that the service quality verification of IoT software will be carried out through the metrics presented in this paper, thereby contributing to the improvement of users' service satisfaction.
