Objectives This research was performed to establish the clinical practice guideline(CPG) for Lesser Yin Symptomatology of Soeumin disease. Methods Dongeui suse bowon(sinchuk edition), textbook for Sasang constitutional medicine, Clinical guidebook for Sasang constitutional medicine, and standardization reports on Sasang constitutional medicine and papers concerning symptomatology of Soeumin Disease, especially Lesser Yin Symptomatology was collected and classified. Additionally experts' conference was held to make agreement on the conflicting issues on a regular basis. Results & Conclusions There was no concerning paper on Lesser Yin Symptomatology. Experts' agreement was needed to establish the CPG. Lesser Yin pattern can be classified into 2 groups; Lesser Yin severe pattern and Lesser Yin critical pattern. There are Lesser Yin pattern accompanied abdominal pain and bowel irritability pattern and Lesser Yin pattern accompanied green tinged watery diarrhea pattern in Lesser Yin severe pattern. There are Visceral syncope pattern and Exuberant yin repelling yang pattern in Lesser Yin critical pattern. Lesser Yin symptomatology has several symptoms like abdominal pain and diarrhea, thirst, oral discomfort, chest discomfort, whole body pain, articular pain and coldness of hands and feet. Additionally there are abdominal pain and diarrhea in Lesser Yin symptomatology accompanied abdominal pain and bowel irritability pattern, there is green tinged watery diarrhea in Lesser Yin pattern accompanied green tinged watery diarrhea pattern and if this symptoms exacerbate, delirious speech and constipation can occur. There are restlessness and coldness on hands and feet in Visceral syncope pattern and severe restlessness and coldness on hands and feet and symptom which the patient cannot drink water in Exuberant yin repelling yang.

A respiration is one of the most useful techniques for vital checking and an abnormal respiration is often the earliest sign of critical illness. Detection of respiration is based on the photo-plethysmography (PPG) with photodiode technique. Because PPG sensor using photodiode can be easily miniaturized, it is suitable for wearable devices. A system to measure respiration rate based on PPG signal is implemented and for a reliable measurement an improved algorithm in accuracy using PPG signal pattern is proposed in this paper. As results regarding to three types of respirations (regular interval, free interval, and weak respiration) the proposed algorithm showed error rate of 0.047, 0.067, and 0.122 respectively.

To query the vast amount of web pages which are available i]l the Internet, it is necessary to extract the encoded information in the web pages for converting it into structured data (e.g. relational data for SQL) or semistructured data (e.g. XML data for XQuery), In this paper, we propose a new web information extraction system, PIES, to convert web information into XML documents. PIES is based on a user-specified target schema and HTML tag pattern descriptions. The web information is extracted by the pattern descriptions and validated by the target schema. We designed a new language to describe extraction rules, and a new regular expression to describe HTML tag patterns. We implemented PIES and applied it to the US patent web site to evaluate its correctness. It successfully extracted more than thousands of US patent data and converted them into XML documents.

In discriminant analysis, we consider an intraclass correlation pattern by principal component analysis. We assume that the two populations are equally likely and the costs of misclassification are equal. In this situation, we consider two procedures, i.e., the test and proportion procedures, for selecting the principal components in classifica-tion. We compare the regular classification method and the proposed two procedures. We consider two methods for estimating error rate, i.e., the leave-one-out method and the bootstrap method.

Halftoning is very important image processing techniques in the digital printing industry which is a process of converting a continuous-tone image to bi-level tone image. In this paper we introduce a new digital halftoning method based on maze generation algorithm as a replacement algorithm of halftoning with space-filling curve. Previous error-diffusion methods based on space-filling curve suffer from regular pattern artifacts from uniform scan pattern. We use maze generation algorithm to remove this undesirable pattern of space-filling curve method.

The bluegill Lepomis macrochirus is an invasive species, not native to Korea, introduced for aquaculture. This species is ranked as a new top predator due to its massive aquatic carnivorous and herbivorous nature by acute vision and the absence of a natural enemy. The visual cells of the retina of L. macrochirus are composed of short single cones and equal double cones and long and bulky rods by light and electron microscopes. In particular, the cones show a regular square mosaic arrangement. This pattern is widely considered as a strong predator. With regard to the visual system, this mosaic pattern may closely be related to a dynamic visual acuity to track and hunt prey.

This study was designed to investigate the changing depositional pattern of inorganic enamel substances during enamel formation and maturation. For this purpose, white rat incisors which continuously grow and develop during the life, were chosen as specimens. And after treated with 20% KOH solution, outer surface of forming inorganic enamel were observed with the scanning electron microscope, dividing into 6 types according to the forming pattern from apical to cuspal direction. The observations lead to the following conclusions: 1. During the initial enamel forming stage, inorganic enamel substances were deposited with very irregular pyramidal shape on the root dentin surface. 2. During the enamel forming stage, inorganic enamel substances were deposited with relatively regular hexagonal, honey-comb appearance. 3. During the later enamel forming stage, inorganic enamel substances were deposited with very irregular and roughly amorphous appearance. 4. During the later enamel maturating stage, very small and round inorganic enamel substances were deposited densely, and made a flat enamel surface.

Tartan, the woven, checked, and wool textile considered by many to be originally from Scotland, has in fact been in use in a range of forms across numerous cultures and during various historical periods. The characteristic checked feature is due to the assembly of different coloured threads in both warp and weft directions which intersect at 90 degrees in a combination known as a sett. For well over one hundred years, different setts and thus different colour combinations have been associated closely with different geographical regions within Scotland, as well as different clans or families. Tartan-type textiles have reached popularity at various times and those have often been a predicted fashion trend suggested, for example, by contributors to fashion gatherings such as Premier Vision in Paris. Often proposed designs are best considered based on tartan combinations rather than simple reproductions. Promotional terms such as "patched checks" or "textured checks" have been common, and often these have been derived from tartan-type constructions. This paper explores novel pattern design methods by identifying the underlying grid structures and proportions exhibited by various well-known tartan setts. The possibility of pattern development from tartan grids and their manipulations is thus the focus of attention. An insight into the methodology associated with the production of original pattern designs is thus provided.

Walking is not only an essential component of the human mobility, but also is a good exercise. Inability to walk freely can reduce an individual's quality of life and independence substantially. Being a relatively low impact activity, walking is particularly good for the elderly and research has shown that regular walking in the elderly reduces the chance of fall-related injuries and mental diseases as well. In spite of the documented benefits of regular walking, it is still difficult to walk without the aid of assistive devices for the frail elderly who have lower extremity problems. Assistive walking devices(AWD), such as crutches, canes, hiking-poles, T-Poles and walkers, are often prescribed to the elderly to make their walking be safe and efficient. Many researchers have demonstrated the effects of AWDs such as reducing lower extremity loading, improved dynamic/gait stability, yet, no study has been done for gait pattern when the elderly gait with AWDs. Therefore, the purpose of this study was to examine whether T-Poles, one of the AWDs, change the elderly gait pattern. Eight community-dwelling female elderly participated in this study. Laboratory kinematics during walking with T-Poles(PW) and with out T-Poles(NPW) was assessed. PW showed significant increase in step width, stride length, gait velocity and decrease in swing time. No significances were found in lower body joint angles but meaningful trend and pattern were found. Maybe the reason was due to the participants. Our participants were healthy enough so that the effect of T-Poles was minimum. PW also showed typical gait phases which are no single support phase during a gait cycle. It indicates that walking with T-Poles may guarantee safe and confident walking to the frail elderly.

Objectives : The climate changes in the natural realm displays pheonomena of excess and deficiency due to the principle of Yiyinyiyangzhiweidao. Here, overabundant qi arises due to the works of multiplication and insultation. When this overabundant qi is in force, the retaliating qi appears without fail to create a parallel. This is the Autonomous Equilibrium Mechanism found in the natural world. Studying this mechanism is deeply significant in understanding the mechanisms of diseases. Methods : The paper is written by reviewing the texts found in Huangdineijing's Chapters of Yunqi, which are $Q{\grave{i}}jiaobiandalun$, Wuchangzhengdalun, $Liuyuanzhengj{\grave{i}}dalun$, Zhizhenyaodalun, and Suwenliuqixuanzhumiyu. Results & Conclusions : The overabundance and retaliation in Five Circuits take the form of the restrained child of the Five Circuits takes revenge on the overabundant qi on behalf of his mother. The overabundance and retaliation in Six Qi take the form of rapid healing of Benqi which was in stagnation. Traditionally, overabundant qi is the only one in existence when the Five Circuits are in excess and the year of Hai yin wu wei you xu's regular transformation. During this time, retaliating qi does not exist. When Five Circuits are in deficiency and in the year of Si shen zi chou mao chen's pattern transformation, both the overabundant and deficiency qis exist. However, regardless of regular transformation or pattern transformation, overabundant qi and retaliating qi cannot exist at the same time. This seems to be the rational conclusion. There are some regulations that overabundance and retaliation follow. First, the strong and weak, and number of days coincide. Second, overabundance qi appear during the first half of the period when the qi of controling heaven is in place. During the later half of the period when the qi of terrestrial effect is in force, retaliation qi is the one that appears. Third, overabundance and retaliation does not end with one time. Rather, they will continue to repeat appearance and disappearance without any set pattern. Fourth, the overabundance and retaliation of the guest qi and dominant qi only has overabundance and no retaliation.
