Nano scale networks are futuristic networks deemed as enablers for the Internet of Nano Things, Body area nano networks, target tracking, anomaly/ abnormality detection at molecular level and neuronal therapy / drug delivery applications. Molecular communication is considered the most compatible communication technology for nano devices. However, connectivity in such networks is very low due to inter-symbol interference (ISI). Few research papers have addressed the issue of ISI mitigation in molecular communication. However, many of these methods are not adaptive to dynamic environmental conditions. This paper presents an enhancement over original Memory-1 ISI cancellation scheme using maximum likelihood estimation of a channel parameter (λ) to make it adaptable to variable channel conditions. Results of the Monte Carlo simulation show that, the connectivity (P_conn) improves by 28% for given simulation parameters and environmental conditions by using enhanced Memory-1 cancellation method. Moreover, this ISI mitigation method allows reduction in symbol time (Ts) up to 50 seconds i.e. an improvement of 75% is achieved.

Airbrushes are being utilized in various industries due to their practicality and ability to express a wide range of designs. Especially in the field of body painting, they have become an essential tool for artists. Airbrushes enable precise color application, shaping, and gradient expression, thereby reducing work time, which has led to their increasing use in the field of body painting. This study aims to present the latest design trends in airbrush body painting by analyzing the design composition, color planning, blending, and expression techniques, focusing on award-winning works in the airbrush-exclusive category of internationally recognized World Bodypainting Festivals. The results are as follows. Firstly, in terms of design composition, emphasis and balance principles are primarily used. The main image is emphasized at the center of the upper body, while a balanced composition with left-right symmetry is observed in the lower body. Secondly, color planning and blending primarily utilize contrasting colors to enhance visibility. Thirdly, all major award-winning works utilize stencil and gradient techniques to accurately depict shapes and add dimension. Based on these analyses, body painting designs were planned and executed using airbrushes. Through such artwork production, the artistic utilization of airbrush body painting is aimed to be popularized, contributing to domestic research in the field of airbrush body painting.

In order to flatter the figures of average middle aged women by determining harmonious proportions for their costume forms, this study evaluates effects of varying design details of jackets(coats) with blouses and slacks using a ranking test and paired comparisons test. The result from clothing design C-2 which has the best design effect were as follows; 1. In order to look taller, the jacket(coats) is divided vertical long line and it has the emphasis point close to the face. 2. In order to make shoulder width look wider, armhole seam line attached 1-2 cm from the shoulder point. 3. In order to make chest width look slimmer, division was made up of a tailored collar with a deep V-neckline. 4. In order to make waist circumference look slimmer, the jacket has more fitted waist line than loosed it and tailored collar with a deep V-neckline. 5. In the case of the division of upper and lower garments, when the division was closer to the golden section, i.e., when the jacket hemline is hipline and slacks length is the heel excluded length of shoe heels, the overall appearance was better. 6. The V-neckline looked better, when it was cut along a long acute angle to the waist line. Because of dividing along above factors 1-6 i.e., clothing design C-2 was overall harmonious. Appropriate division of costume forms made for an aesthetic composition, which flattered the body types of middle aged women and presented harmonious, beautiful costume design effects. It made the women look taller, slim and balanced, and highlighted middle aged women's sense of beauty.

The purpose of this study are to examine the characters of the lower half body shape in the middle aged women and to make slacks patttern on the base of four difference body shapes as follows. The lower half body shapes were classified into 4 types on the basis of their lateral view silhouette, whose characters were summarized as followings. (1) "Type 1" meant the right body shape with the standard protrusion of abdomen and hips. (2) "Type 2" showed the body shape with prominent hips, which had the flat abdominal silhouette and the greatly curved hips silhouette. (3) "Type 3" was the body shape with the prominent abdomen and the flat hips, in which the frontal view silhouette of the abdomen was greatly curved and the rear view silhouette of hips is less curved. (4) "Type 4" was characterized with prominent abdomen and hips. The slaks patterns were based on the lower half body shape characters and resulted in followings. (1) In the type 1, little difference from conventional patterns was seen in experiment pattern, in which the front waist girth was W/4{\times}0.5cm+0.5cm+fold(2.5cm) and the back waist girth W/4+0.5cm-0.5cm+dart(3.5cm). The front hip girth was defined as H/4+2.0cm+0.5cm and the back hip girth as H/4+2.0cm-0.5cm due to its increased ease amount produced by abdominal fat deposition. (2) In the type 2 experimental pattern, the front and back differences of the waist girth and the hip girth were defined as 1.0cm and 2.0cm separately. Accordingly, the front waist girth was W/4+0.5cm+ 1.0cm+fold(2.0cm), the back waist girth W/4+0.5cm-1.0cm+dart(6.5cm), the front hip girth H/4+2.0cm+1.0cm and the back hip girth H/4+2.0cm-1.0cm. (3) In type 3, the front waist girth was set up as W/4+0.5cm+0.5cm+fold (4.5cm) for the increased front fold amount and the back waist girth was W/4+0.5cm+0.5cm+dart(3.0cm). The front hip girth was made as H/4+2.5cm+0.5cm and the back hip girth H/4+2.5cm-0.5cm. (4) In type 4, considered were $\circled1$ the increased fornt fold amount due to the abdonimal protrusion, $\circled2$ the increased back dart amount and the decreased back dart length owing to the hips prominent and $\circled3$ the front and back differences of waist and hip girth for the lateral view silhouette. Therefore the front waist girth was defined as W/4+0.5cm+2.0cm+flod (5.0cm), the back waist girth as W/4+0.5cm-20.cm+dart(4.0cm), the front hip girth as H/4+2.0cm+1.0cm and the back hip girth as H/4+2.0cm-1.0cm. The sensory evaluation of appearance and comfort was appeared more suitable on the experiment pattern than on the conventional pattern.

This study deals with the flow of bed rock ground water of Banyaweol Formation, which is presently cleared up as a laminar flow. The result obtained may be summarized as the following. 1) The Banyaweol Formation consists mainly of thin-bedded, green to blackish green shale, mudstone, and marl. The marl and mudstone alternatively occur with shale. The marl and mudstone form a aquifer of Banyaweol Formation. In this study, a group of aquifer is in convenience named as a aquifer zone. The aquifer occurs in lenticular form. The aquifer seems to be a type of artesian aquifer because it is covered with aquicludes, but it actually forms a unconfined aquifer because its piezometric surface stays under the lower aquiclude. The lowering of piezometric level is formed because of leakage of the ground water to the lower aquifer undersaturated. 2) The coefficient of permeability of Banyaweol Formation's ground water body (K) is derived by using Dupuit's equation as the following ${\log}K=\frac{CK^2-dK+f}{aK-b}\;\(M=1.365(2H-s)s\\M={\log}1.956s{\sqrt{H}}r\)$ here, $$a=\sum_{1}M_iG_i$$ $$b={\frac{1}{2}log{\sum_{i}}Q_i{^2}$$ $$c=2{\sum_{i}}M_i{^2}$$ $$d=loge{\sum_{i}}M_{i}Q_{i}+2{{\sum_{i}}N_{i}Q_{i}$$ $$f=loge{\sum_{i}}Q_i{^2}N_i$$ If the measured values substituted for the above equation, the coefficient of permeability of the aquifer is 4.1m/day. The coefficient of storge of the aquifer is $2.8{\times}10^{-4}$ if the measured values substituted for Theis's equation. Using the above constants, the filtration velocity of the aquifer is $2.1{\times}1O^{-1}m/day$and the daily flow quantity of the ground water is $847.38m^{3}/day$. 3) In order to understand the time necessary for a circulation of ground water body, the contents of tritum contained in the ground water are measured as 2.3 T.U. at the Korea Atomic Energy Research Institute. Before 1952, the average concentration of tritium per year in groundwater was reported as 10T. u., taking it as the standard, the groundwater of the present study 26.25 years old. Therofore, the groundwater of the Banyaweol Formation is judged as an relatively old groundwater. It is characteristic that the ground water of Banyawol Formation is laminar flow as well as unconfined aquifer and ground water flow of relatively long time. 4) The nature, means of flow, and circulation of Banyaweol Formation's ground water body make it possible set up this ground water body as a ground water system.

Background : Eight-Constitution Medicine (ECM) devides the human body into eight constitutions. Up until now, checking the pulse types is only way to classify the eight constitution. Recently we try to make a questionnaire that is based on the Eight-Constitution characters and analyze the answer from patients who were classified into one of the eight constitutions according to their pulse types and their responses to constitution-acupuncture therapy Objective : This study intends to analyze each answer of the Eight-Constitution Questionnaire with independent sample t-test. Methods: Participants of this study were outpatients in ECM clinics located in Korea. The resources were collected from 925 patients who were classified into one of the eight constitutions according to their pulse types and their responses to constitution-acupuncture therapy. SPSS 13.0 for Windows was used for independent sample t-test. Results and Conclusions: 1. The proportion of participants' constitutions is in the order of Pancreotonia (28.0%), Colonotonia (17.3%), Pulmotonia (18.1%), Hepatonia (18.1%), Vesicotonia (8.5%), Cholecystotonia (7.0%), Renotonia (2.6%) and Gastrotonia (0.4%). 2. Eight-Constitution Questionnaire consists of 5 parts; Appearance, Character, Body reaction, Physiology & Pathology and Food reaction. 3. 44 items were chosen among 128 question about Body reaction, Physiology & Pathology and Food reaction. 4. Due to the deficiency of Gastrotonia examples, useful items have to be given up. If we can gather Gastrotonia examples, we can use meaningful items more than 44.

The conventional model did not take momentum conservation into consideration when the electron absorbs and emits the photons. II-ray provides momentum conservations on any directions of the entering photons, and also the electrons have radial momentum conservations and fully elastic bouncing between two atoms, in the new atom model. Conventional atom model must be criticized on the following four points. (1) Natural motions between positive and negative entities are not circular motions but linear going and returning ones, for examples sexual motion, tidal motion, day and night etc. Because the radius of hydrogen atom's electron orbit is the order of 10$^{-11}$ m and the radia of the nucleons in the nucleus are the order of 10$^{-l4}$m and then the converging n-gamma rays to the nucleus have so great circular momentum, the electron can not have a circular motion. We can say without doubt that any elementary mass particle can have only linear motion because of the n-rays' hindrances, near the nucleus. (2) Potential energy generation was neglected when electron changes its orbit from outer one to inner one. The h v is the kinetic energy of the photo-electron. The total energy difference between orbits comprises kinetic and potential energies. (3) The structure of the space must be taken into consideration because the properties of the electron do not change during the transition from outer orbit to inner one even though it produces photon. (4) Total energy conservation law applies to the energy flow between mind and matter because we daily experiences a interconnection between mind and body. An understanding of the mechanisms responsible for the control of normal proliferation and differentiation of the various cell types which make up the human body will undoubtedly allow a greater insight into the abnormal growth of cells, A large body of biochemical evidence was eventually used to generate a receptor model with an external ligand binding domain linked through a single trans-membrane domain to the cytoplasmic tyrosine kinase and autophosphory-lation domains. The ligand induced conformational change in the external domain generates either a push-pull or rotational signal which is transduced from the outside to the inside of cell.l.ell.

A simulation using the finite-difference time-domain method to analyze the electromagnetic interactions between a cellular phone and the human body was conducted, and a synthesis of a bone-equivalent material to make a human head phantom was performed. A test model of the cellular phone was fabricated to measure its reflection coefficient and radiation pattern in the free space. Various effects of the human body on the characteristics of the phone, such as input impedance, reflection coefficient, radiation pattern, and radiation efficiency are analyzed as the distance between the head and the phone antenna varies. When the phone was operated close to the head, the resonant frequency of the antenna decreased by up to 12%. With the output power of 0.6W, as long as the distance was larger than 30mm, the 1-g averaged peak SAR was below the ANSI/IEEE safety guideline, 1.6 W/kg. To synthesize the bone-equivalent material, an epoxy with hardener and a graphite powder were used as basis ingredients, and a small amount of a conducting epoxy was added to control the conductivity of the material. A material having a relative permittivity of 18.04 and a conductivity of 0.347, which are close to those of the bone at 850 MHz, was synthesized.
