The ultrafine particle researches in the fields of new materials processing, air pollution, semiconductor manufacturing processes, and sensor manufacturing are growing rapidly. The most commonly used conventional techniques to generate ultrafine particles are the atomization of liquid with high pressure air and the evaporation and condensation processes of solid metals and salts. The atomization process can usually generate particles from several tenth of micron to several microns sizes and the size distributions are usually broad. The evaporation and condensation method can generate particles from a few nanometer to several nanometer sizes with fairly monodisperse distributions. However, this technique requires high temperature oven and rapid cooling system which makes the particles generation system bulky and hard to handle. In this study, a new ultrafine particle generation technique is investigated using electrohydrodynamic (EHD) spray method. This technique can usually generate a few nanometer size particles with high electric field. When a liquid is injected through a ca. 100μm hole a high electric field is applied between the injection hole and the ground plate, which makes very steep electrical potential gradient near the injection hole. This strong potential gradient makes the liquid surface break, consequently forming small droplets. The particle sizes are found to be in the ranges of a few tens of nanometers with bimodal distributions. It was also found that the mean sizes were increased as the atomizing liquid solution concentration increased.

渤海國의 서쪽 邊境에 관한 연구

韓圭哲 부산경남사학회 2003 역사와 경계 Vol.47 No.-

Iasserted there was the Liaohe River(遼河) in between the guard of the Parhae(渤海, Bohai, 698∼926) and the Tang(唐, 618? - 907) dynasty. Some old reports on the guard said that it was the line of the Bozhuokou(박작구) of the entrance of Aplok River(鴨綠江) and Xincheng(新城). Namely, the Liaodong(遼東) area was not included in the territory of Parhae. But based on some reasons I asserted that area was a part of the territory of Parhae. First, the establishment of the kingdom could be successful because the remainders of Koguryo live in that area, Secondly, the influence of the Andongduhufu(安東都護府) on the colonial ruling organizations of the Tang dynasty was almost absent. Thirdly, it is to be confirmed that it resulted from the war between Parhae and Tang in the eighth century, through such sea and land routes as Dengzhou(登州) and Madushan(馬都山). Fourthly and lastly, it followed the process of the war between Parhae and Kithan on the area of Liaodong in the tenth century.

정규현 진주산업대학교 1975 論文集 Vol.13 No.-

By the research on military drill subject(by free description) what students wanted was as follows: 1. Junior college students who completed military drill subject also wanted to receive the legal guarantee of shortening period of military service. 2. Students wanted to have free hair style by modern fashion. 3. As the military drill has much tendency to leaning on the part of art, they are prone to be tired and feel the sense of burden. Through the above research, (except benefit of shortening military service) in group drill or action they are inclined to make alight of “the whole” because of self-indulgence Therefore, the fundamental problem 1ies in moral education and so there must be human contact between drill instructors and students and the former must let the latter understand by personal correction and through individual and group guidance we can correct their wrong attitude, but if junior college students could receive the benefit of shortening the period of military service 1ike the college students, they would cleanse educational tone and participate in guidance wil1ingly with the sense of pride and honor as “Student”.

발해의 고구려 역사 계승 문제

한규철 한국고대사학회 2004 韓國古代史硏究 Vol.33 No.-

The Chinese argument that Parhae was not independent is based on the fact that a tribute - investiture relationship existed between Parhae and Tang Dynasty. Under this system, they argue, a king of Parhae was invested in with the title of "governor - general of Holhan Province" of the Tang Dynasty. But, even if we acknowledge the influence of the Tang Dynasty over East Asia, the investiture relationship at the time should be understood as a diplomatic formality in connection with the approval of royal successions, not as an act of governing provincial regimes of the Tang Dynasty. Also, a tributary relationship is widely regarded as a type of official trade between the dynasties. According to the New History of the Tang Dynasty, Parhae always used its "own era names" and "freely offered" posthumous titles to deceased kings without Tang's approval. Furthermore, the epitaph uncovered from the tomb of Princess Jeonghyo, the fourth daughter of third king Mun revealed that Parhae called itself an empire like China and its king was addressed as the "emperor." In fact, Parhae was so independent as to launch an attack on Tang in A.D. 732 to prevent contacts between Tang and the "Heuksu Malgal" tribe under its control. It should be acknowledged that Parhae succeeded Koguryo, because the state of Parhae was founded in the former territory of Koguryo and its population mostly consisted of Koguryo people, even though a number of Koguryo people had been forcibly relocated to other areas following the downfall of Koguryo in 668. In other words, the argument that the Malgals suddenly filled the old Koguryo territory lacks credibility. The argument that Parhae was composed of the Malgals is based on the New History of the Tang Dynasty, which describes Dae Jo - young, the founder of Parhae, as a Malgal tribesman. Another reason with which the Chinese deny the relationship between Koguryo and Parhae is that both Old History and New History of the Tang Dynasty put Koguryo in the section of "Eastern Barbarian Dynasties," while Parhae was included in the section of "Northern Barbarian Dynasties." However, the History of Sui Dynasty put Koguryo and Parhae together in the Eastern Barbarian section. In this context, we can detect the fact that the history writers since the Old History of the Tang Dynasty maintained a dynasty - centered historical perspective. Under this approach, they could not acknowledge Parhae, which was created 30 years after the fall of Koguryo, as a country that inherited Koguryo. In any case, it is an unmistakable fact that Parhae was a kingdom established in succession of Koguryo in terms of territory as well as the inhabitants. It is utterly unreasonable to argue that the Malgals suddenly replaced all Koguryo people in the old Koguryo territory or their population suddenly increased to outnumber the indigenous Koguryo people. In addition, the key to understanding the composition of Parhae inhabitants is the fact that the tribal name "Malgal (Mo - ho)" was given by outsiders, not by the Malgals themselves. It is widely known that the forbearers of Malgal were Suksin before the Qin Dynasty and Eup - ru during the Han Dynasty. These names were not used by the tribes themselves but were coined by different Chinese dynasties to refer to various "uncivilized" barbarian tribes around the periphery. It is unlikely that the Malgal people would change their own tribal name, or would they be willing to use such derogatory word as "Malgal." The term "Malgal" was coined based on the old Sino - centric and dynasty - centered historical perspective as a general term referring to ethnic minorities in the Northeastern borderland of the Tang Dynasty. It was also a derogatory name for the inhabitants living in the periphery of Koguryo. In other words, the term "Koguryo people" were used to refer to the residents in and around the capital Pyongyang and the people residing in outlying areas were called the uncivilized "Malgals." Records describe Dae Jo - young, the founder of Parhae, as "a Koguryo eccentric" or "a Sokmal Malgal." But, these descriptions of him do not mean that he could be either a Koguryo person or a Malgal person. It simply means that he was a "villager from the Songwha River in Koguryo." By the same token, it is also clear that the ethnicity of the ruling class and the ruled could not have been different. We learn from the Old History of the Tang Dynasty the fact that Parhae succeeded Koguryo. The book says that the "customs of the two dynasties were the same." Customs generally include established practices related with the ceremonies of coming - of - age, marriage, funeral and ancestor memorial, as well as the language. So, the Chinese records themselves testify to the successive relationship between the two Korean dynasties. This relationship can also be confirmed through their shared cultural heritage. There are certain lasting traditions in human societies that do not change even with the passage of time. Among them are the burial style and the heating system. For the tombs of Koguryo aristocrats, they relied mainly on masonry, such as stone chambers, stonewall and stone coffins. Parhae inherited this tomb style; a group of royal tombs in Yongcheonbu, the capital of Parhae, including the Tomb of Three Spirits (Samryeong Bun), were built in this manner. In the past, the earthen tombs in Parhae were thought to be the Malgal's typical grave pattern. Today, however, this type of tomb is known as a burial style for the commoners of Parhae, not a burial pattern of Malgal, which is a different tribe. All the commoners of Kognryo and Parhae were buried in earthen mounds and this type of burial was universal at the time. Korea is the only country in the world where people with the last name "Tae" exist, and they claim they are the descendants of Dae Jo - young, the founder of Parhae. Korea is also the only country in the world where apartment houses are equipped with "Ondol," the traditional "hot -floor" heating system. The Ondol (warm rocks) system originated from Koguryo and the Parhae people also used the system. In the Old History of the Tang Dynasty, there is a description of Ondol: "In Koguryo, lives of ordinary people are mostly poor. In winter, a long hole is dug under the floor of a room and people keep charcoal fire there to keep the room wann." The Ondol strucrures are found in the Koguryo relics in Pyongyang and Jiban (presently Jian, Jilin Province, China). They are also discovered in the royal palace site in the capital of Parhae and the kingdom's surrounding areas such as the Littoral Province. All these findings are evidence that testifies to the successive relationship between the two Korean dynasties.

Accounting priciples are the accounting theories systematized synthetically. So they are the principles to explain accounting theory and the guides of corporate accounting practices. Therefore, the establishment of accounting principles is not only an important task of accounting, but also closely related with development of industrial society indispensably. The nature of accounting principles may study various aspects of a subject as follows. 1. Accounting principles are the guide of action which must be followed in accounting practices. 2. Accounting principles have universal validity. 3. Accounting principles are normative. 4. Accounting principles have an attribute to change. 5. Accounting principles should be formed through the logical reasoning process. The study of accounting principles made active progress with it has published works relating to establishment of accounting principles by AICPA and AAA. Accounting principles established by the accounting institutions as AICPA, AAA, FASB, SEC, and IASC which had set up professional organization in order to establish accounting principles, and has study about the accounting theory. In Korea, Corporate Accounting Principles were set and published in 1958, and Accounting Standards applicable to Listed Companies in 1974, for the first time. Thereafter, they have revised in 1976 first, and in 1980 second, and it is required to apply from the opening fiscal year at January 1, 1981. The contents of revised accounting principles may classify into some main classes as General provisions, Financial Statements, Balance Sheet, Statement of Income, Valuation of Assets and Liabilities, Statement of appropriation of retained earnings, and Statement of Changes in Financial Position.

According to the enlargement of the size of business and diversification of managemetal forms owing to the development of the economic society, rationalization of management is much required. For the realization of rationalization of rationalizalion of management, establishment of a real accounting system which can be adapted to the real society is required.With this, our country has had much change and development in theories and practical affairs on accounts of business in the 70's. Moderate expression about assets of sitiuation of business and outcome of management at a definite time is very important not only to financial accounting but also to managerial accounting. For transmission of accurate accounting imformation to interest groups, proper practical affairs of accounting must be accomplished and title of accounting may be regarded as elemental unit of practical affairs of accounting. At such a point I would like to arrange with synthesis and study various problems on setting allowance. Allowance is a kind of arrangement-account which indicate reservation to assets of uncertain form a specific sum of money that, not to be paid for a spectfic purpose, is based on a definite standard as a preperation that may be a burden in pertinent year for a certain purpose. Conditions that can be an account are like following.First, a cause of expense should happen in pertinent year and a need that it be calculated as an expense in pertinent year should be acknowledged for a proper imformation of profit and loss.Second, it should not be paied in a pertinent year.Third expense will surely be expected in pertinent year. Valuation reserve means a allowance account having some qualities of valuation and allowance for depricition and allowance for bad debt are representive account and it is also be maid as cancelling account or balance account. Because it is impossible that a certain sum of money is directly subtracted from a certain account, it is a peculiar account of an art of calculation that is setting up with contrast arid with indirect subtraction form from a certain account, so.on a balance street, it shall be expressed as a form of indirect subtraction from a assets account. Liability reserve is, to have a surely expense, being the cause of happening in calculation year, an accumulation as preperation on unpaied case. In the future the happening of definite expenditure is surely expected and the cause of expenditure is already existed in a pertinent year and the sum of money of expenditure can be rationally calculated.We can appropriate as liability reserve the sum of money of expenditure that is burdened on profit and loss in that year after above lines are sufficiently satisfied .Allowance for repairs, reserve for retirement allowance are representative. Special allowance is with price fluctuation reserve and reserve for insurance, desired event being happened, the property is decreased as much or debts being happened, supplemented for the money for preperation.When it is not happened, this account moved into splus.That is to say, this account has the middle obsecure quality between surplus and liability. Reflected on policy of taxation business a series of measure like tee obtaining of foreigncurrency, reclamation of overseas markets, advancement of export, reserve of reclamation of overseas markets that is reconized as a loss are special allowance.
