The origin and structural development of Do-po have been studied with a consideration of the back piece of Do-po in this paper. This study found that Do-po was in this paper. This study found that Do-po was originally imported from China. This paper reports that an earlier record on Do-po is found in an epitaph(1564) than the record found in S njoSilnok(1607) which is conventionally known as the earliest record on Do-po. The structure of Do-po has been widely known as an“attachment of J n-sam”on slitted back piece of the outwear. However, this study shows that Do-po has been formed by inserting the gusset of the front piece into the back piece of the outwear Jik-nyung. This change can be considered as the economical and practical needs to save the cloth or by the aethetical need of simpler clothing. This study also classifies the shape of gussets largely into nine classes according to the temporal development in the shape of gussets.

This research was carried out to elucidate the impacts of dissolved oxygen (DO) concentration to phosphorus release mechanism from soil into water in lakes. $PO_4-P$ contributed to the growth of the total phosphorus (T-P). $PO_4-P$ was steadily increasing because water was accumulating $PO_4-P$. T-P was closely related to turbidity, pH, and DO. We found that DO had decreased because DO was consumed in organic matter decomposition, and that the resulting anaerobic decomposition occurred whenever water had run out of DO. We also found that pH had decreased sharply by production of organic acid by the anaerobic decomposition and that T-P decreased because a decrease in pH removed turbidity by precipitation. T-P was dissolved without microbial decomposition. This mechanism was of great importance in lakes because phosphorus is released from soil into water.

This paper aims to clarify the residential quarter organization and housing spatial form of fishing village in Jeonjang-po, Imja-do Island. The results are as follows. First, the place of residence in Jeonjang-po was located in the place having the south and the north seaside, and the road system was presented by form to connect the north and south. Second, the alley of these north and south direction has a dynamic scenery, but the alley of east-west courses has a horizontal scenery. Third, it is a characteristic that there is very more plottage than the building area of the residential quarters. The reason that plottage has a big is because inner court in the residential quarters are used as places such as the fishery works and the vegetable gardens. Finally, the fishing village house in Jeonjang-po is 4-bay type building is typical type when seeing from the front, and is to have entrance hall at the front of building.

The core of the block chain technology is solving the problem of agreement on double payment, and the PoW, PoS and DPoS algorithms used for this have been studied. PoW in-process proofs are consensus systems that require feasible efforts to prevent minor or malicious use of computing capabilities, such as sending spam e-mail or initiating denial of service (DoS) attacks. The proof of the PoS is made to solve the Nothing at stake problem as well as the energy waste of the proof of work (PoW) algorithm, and the decision of the sum of each node is decided according to the amount of money, not the calculation ability. DPoS is that a small number of authorized users maintain a trade consensus through a distributed network, whereas DPS provides consent authority to a small number of representatives, whereas PoS has consent authority to all users. If PoS is direct democracy, DPoS is indirect democracy. This study aims to contribute to the continuous development of the related field through the study of the algorithm of the block chain agreement.

Existing PoS (Point of Sale) based payment frameworks are vulnerable as the Payment Application's integrity in the smart phone and PoS are compromised, vulnerable to reverse engineering attacks. In addition to these existing PoS (Point of Sale) based payment frameworks do not perform point-to-point encryption and do not ensure communication security. We propose a Smart and Secure PoS (SSPoS) Framework which overcomes these attacks. Our proposed SSPoS framework ensures point-to-point encryption (P2PE), Application hardening and Application wrapping. SSPoS framework overcomes repackaging attacks. SSPoS framework has very less communication and computation cost. SSPoS framework also addresses Heartbleed vulnerability. SSPoS protocol is successfully verified using Burrows-Abadi-Needham (BAN) logic, so it ensures all the security properties. SSPoS is threat modeled and implemented successfully.

Sequential estimation of parameters in a compound Poisson process whose jump sizes are one-parameter exponential class random variables is discussed. Cramer-Rao type information inequality is used as an efficiency cirterion. Unbiased estimators for certain parametric functions whose variance attain the lower bound are all characterized with the corresponding sampling plans.

In order to determine the effect of iron depletion and subsequent supplementation on the muscle capacity for peroxisomal (PO) and mitochondrial(MO) $\beta$-oxidation during high fat feeding, weanling rats were fed a 44% (HF) or 2.5% (LF) fat diet with (+Fe) or without (-Fe) iron for 6 or 9 weeks. After 1 week rats fed HF+Fe or HF-Fe had 50-100% more PO and MO in heart, soleus, psoas and gastrocnemius than did rats fed low fat, but after 3 weeks rats fed HF-Fe had lower muscle PO and MO. In muscles of iron depleted rats PO and MO were not increased by supplementation with iron for 3 weeks. After 6 weeks MO and PO in skeletal muscles of rats fed HF+Fe were lower than after 3 weeks. It is concluded that adequate iron is necessary for miaximum response of muscle PO and MO to high fat feeding. However, after 6 weeks both PO and MO have returned to levels similar to those of rats fed low fat diets, hence, the elevated catalase activities seen at this time do not reflect peroxisomal $\beta$-oxidation.

This study examines the men's coats in the early $17^{th}$ century through the excavated costumes of Kim, Hwak($1572{\sim}1633$)'s tomb. Kim, Hwak was a literary man with a high government position. After the Japanese Invasion of Korea in 1592, in the early $17^{th}$ century, there were many changes with the kinds and form of men's coats. From Kim, Hwak's tomb, there excavated 8 kinds of coats; Sim-ui, Dan-ryung, Jik-ryung, Cheol-rik, Do-po, Chang-ui, Joong-chi-mack, So-chang-ui, and they are 27 items. The characteristics of $17^{th}$ century costumes are well seen from these coats. Up to that period, Cheol-rik was worn as ordinary clothes, but from Kim, Hwak's tomb, there are 5 pieces of Do-po, and 15 pieces of Joong-chi-mack. This tells us that these items were widely worn after the $mid-17^{th}$ century.

The Woo-Whang-po-Lyong-Whan has been used as one of the traditional medicines in the field of pediatrics so far since Song dynasty, and still it is widely being used nowadays. It might be considered to be a contribution to do further basic experimental studies on antipyretic, anticonvulsive and analgetic action of the Woo-Whang-po-Lyong-Whan. So it's pharmacological studies were carried out comparing to control drugs. ?Following conclusions were obtained. 1. It's antipyretic action was compared to that of aspirin by Writhing response using acetic acid-method. Mice were given one twentith, one tenth and one fifth tablets of the Woo-Whang-po-Lyong-Whan per Kg of body weight, respecitively. Writhing syndrome frequencies were noted as 38.4 in control group. and $18.0{\pm}12$, $13.17{\pm}2.28$, $7.33{\pm}12$ in above esperimental groups, respectively. In aspirin group it was $18.5{\pm}1.0$ when 2mg aspirin per body weight of mice was given. So it was recognized that antipyretic action of the Woo-Whang-Po-Lyong-Whan become remarkable by increasing amounts of the Woo-Whang-Po-Lyong-Whan. ?2. Antipyretic action in normal temperature mice group was not significant by increasing concentration of the Woo-Whang-Po-Lyong-Whan, but body temperature dropping in normal mice group was slightly noted than control. group, but less temperature dropping was noted than aminopyrin group. ?3. In fever provocated rats groups using Salmonella typhimurium, antipyretic action of the Woo-Whang-Po-Lyong-Whan was not observed significantly than control group. And slight antipyretic action was noted in aminopyrin group. So that antipyretic action of the Woo-Whang-Po-Lyong-Whan was not significant than those of general antipyretic used nowadays, but slower action was recognized. ?4. Anticonvulsive action of the Woo-Whang-Po-Lyong-Whan was studies comparing to that of phenobarbital. Action was not remarkable than phenobarbital, but was significant than control group. No significant intesifying action was noted by increasing amounts of the Woo-Whang-Po- Lyong-Whang.
