In this paper, we examine the problem of estimating the sensitive characteristics and behaviors in a multinomial randomized response (RR) model. We analyze this problem through a Bayesian perspective and develop a Bayesian multinomial RR model in survey study. The Bayesian inference of multinomial RR model is a new approach to RR models.

In this paper, we propose a novel methodology to identify border gateway protocol (BGP) updates associated with major events - affecting network reachability to multiple ASes - and separate them (statistically) from those attributable to minor events, which individually generate few updates, but collectively form the persistent background noise observed at BGP vantage points. Our methodology is based on principal component analysis, which enables us to transform and reduce the BGP updates into different AS clusters that are likely affected by distinct major events. We demonstrate the accuracy and effectiveness of our methodology through simulations and real BGP data.

Finite difference schemes are considered for a $Ca^{2+}$ diffusion equations with damping and convection terms, which describe $Ca^{2+}$ buffering by using stationary and mobile buffers. Stability and $L^{\infty}$ error estimates of approximate solutions for the corresponding schemes are obtained using the extended Lax-Richtmyer equivalence theorem.

This study was performed to report the effect of coffee enema among detoxification Therapy on atherosclerosis. Russian patient was treated by coffee enema, acupuncture, herbal medicines, exercise, cupping, korean physical therapy, chuna manipulation treatment and moxibustion. The state of patient was measured by Infrared Thermography, Blood Vessel Stasis Test and Minnesota Nicotine Withdrawal Scale. After treatments, both feet temperature were increased. And index of indicating the occlusion of the lower body was improved. Also, Minnesota Nicotine Withdrawal Scale scores were improved. It means the patient was successful at non-smoking during hospitalization. These results suggests that atherosclerosis was improved. According to above results, coffee enema was effective to improve the atherosclerosis. More studies should be followed.

SPT-CL J2106-5844 is the most massive galaxy cluster at z>1 discovered to date. It has been known to be an isolated system with a singular, well-defined halo. However, recent studies provide lines of evidence for its merging state. We strengthen the case with the multi-wavelength observations from ALMA, ACA, ASKAP, ATCA, and Chandra. With the sensitive, high resolution ALMA+ACA observations, we reconstruct the ICM pressure map from the thermal SZ effect. It reveals two main gas components that are associated with the mass clumps inferred from the weak-lensing analysis. Furthermore, the X-ray hardness map supports the bimodal gas distribution. With these multi-wavelength data, we probe the merger phase in SPT-CL J2106-5844.

BGP route flap damping(RFD) was anecdotally considered to be a key contributor to the stability of the global Internet inter-domain routing system. However, it was recently shown that RFD can incorrectly suppress for substantially long periods of time relatively stable routes, i.e., routes that only fail occasionally. This phenomenon can be attributed to the complex interaction between BGP path exploration and how the RFD algorithm identifies route flaps. In this paper we identify a distinct characteristic of BGP path exploration following a single network event such as a link or router failure. Based on this characteristic, we distinguish BGP route updates during BGP path exploration from route flaps and propose a novel BGP route flap damping algorithm, RFD+. RFD+ has a number of attractive properties in improving Internet routing stability. In particular, it can correctly suppress persistent route flaps without affecting routes that only fail occasionally. In addition to presenting the new algorithm and analyzing its properties, we also perform simulation studies to illustrate the performance of the algorithm.

Obesity is not classed in general psychiatry disease. But, psychoneurotic factor has been known to be a risk factor of obesity. In order to evaluate and understand the psychoneurotic state on obese patient, this study used Minnesota Multiphasic Personality Inventory(MMPI). Total patients were classified into 3 or 5 clusters. MMPI scores were compared according to education, BMI and Sasang Constitution. Multiple regression analysis were used for psychological factor on obese patients by age, height, weight, education, percent body fat, fat distribution, BMI. Based on this study, it was no significantly difference by education level, BMI, sasang(四象) constitution except L profile according to BMI. These result is different from our general recognition of the psychoneurotic state on obese patient. Therefore, the bigger sample study is needed.

The objective of this research is to provide basic materials for future development of unit household plane of lease apartment house by comparing and analyzing the unit household plane of SH Corporation lease apartment house in Korea and PHA apartment house in the state of Minnesota, USA. For this purpose, the researcher chose 8 SH Corporation lease apartment houses in Yangcheon-gu Korea and 16 PHA apartment houses in St. Paul, Minnesota, USA. Drawing of 8 complexes of Korea SH Corporation, literary materials collected by Korea House Corporation and SH Corporation and the plane of USA were analyzed and the unit household plane of Korea and USA were processed by CAD to ensure exact analysis. Based on the drawing for CAD, the materialization work was implemented. The total size of materialized drawing and size of each room was drawn by using 'CAD POWER 2005' program. The result of this research is as follows. The plane of SH Corporation lease apartment house shows the difference in the plane composition from 12 pyung. Since LIVING ROOM is described in the drawing, the living room and bedroom seen in the existing size less than 12 pyung become independent as they are separate. While SH Corporation is composed in the form of kitchen that functions as dining room, living room functions as dining room in PHA. While SH Corporation shows 5 types, PHA shows different pattern in each complex. This is probably because PHA has diverse complexes. All planes of SH Corporation have entrance, which reflect the own character of Korea as it is. In PHA, the portion of receipt and storage space is very high.

1. Objectives The purpose of this case is to report that a Soeumin patient with cognitive disorder from traumatic head injury needed to be managed with the consideration of the difference of Nature and Emotion(性情). 2. Methods To evaluate the patient's cognition disorder and mental state, we performed the MMSE(Mini-Mental State Examination) and the MMPI(Minnesota Multiphasic Personality Inventory). and he was diagnosed as Soeumin and treated by Kwakhyangchungki-san(藿香正氣散) mainly. 3. Results and Conclusions (1) In this case, we observed specifically-biased Nature and Emotion(性情) of Soeumin like ‘恒欲處而不欲出’, ‘恒欲爲雌而不欲爲雄’, ‘喜別人之助己也’. ‘喜好不定’, ‘不安定之心’ (2) The management of Soeumin with cognitive disorder from traumatic head injury is that he or she should live together his or her family, and have an active manner with a generous and broad-minded mental attitude. (3) A therapist must give a patient mental support and inspire him or her with courage. (4) The deviation of Nature and Emotion(性情) should be taken into consideration when we manage the patient with cognitive disorder from traumatic head injury.

The meanings of colors vary with time and space. For the most important events in a person's life, such as wedding or funeral, people use color to symbolize their identities or roles. Traditionally, the colors of dress had indicated the wearer's age, class, or marital status in Korea. However, Korea's exposure to western cultures has affected in many dimensions of its modern history. Especially, influenced by social change, the traditional dress has undergone many modifications in forms, silhouettes, materials, and color. However, women's mourning dress has been maintained as a long lasting tradition and the use of white in mourning dress has been regarded as a norm until recently, while men have worn a regular black suit with a black tie. But, the shift from white to black in mourning dress has been observed in recent mourning practices. To examine this change of color in Korean traditional mourning dress, a historical approach utilizing multiple resources, such as interview, observations of events, documents, and archival records was applied.
