The various technologies of the science and technology field were systematized to manage information, personnel and R&D activities related to S&T effectively. The resulting “National Standard Science and Technology Classification” which were composed of 19 areas, 160 divisions and 1,023 categories could contribute to establish rational S&T policy. “National Standard Science and Technology Classification” is synthetic in national level because they include all areas of S&T activities. 5 criteria, which were inclusiveness, exclusiveness, likeness, scale and universality, were used to exert every effort in including the opinion of all experts and to consider harmony between S&T areas. In addition, “National Standard Science and Technology Classification” was prepared to be interchangeable with various classification which were used in other R&D management institutes under the different ministries.

The purpose of this paper is to study logical status and meaning of '$l{\grave{e}}i$[類]' in integrated concept system of 'míng[名]'. The subordinate relationships and integrated systems between genus and species are made up 'míng[名]' in pre-Chin's logical arguments. And '$l{\grave{e}}i$[類]' is a concept that designate what kind of category in all names of sorts and kinds in early China. The logical argumentations of early Chinese philosophers reflect subordinate relationship and integrated system of 'míng[名]'. And then early Chinese philosophers use the 'míng[名]' in other to denote a general concept that totally indicate meanings of genus and species like as Confucius' '$zh{\grave{e}}ng$ míng[正名]'. However early Chinese philosophers make philosophical issues of correspondence between míng[名] and shí[實], not subordinate relationships between genus and species. And then they use the 'míng[名]' in other to denotes not a general concept but a kind of category. Therefore the concept of 'míng[名]' used as a meaning of general concept and sorted out integrated concept system of 'míng[名]' as two categories of míng[名] and shí[實] at the same time in logical argumentations of early Chinese philosophers. The '$l{\grave{e}}i$[類]' of pre-Chin difference from genus of Aristotle spontaneously and conceptually. It is not a concept that in other to compose subordinate relationships and integrated systems. It is not a kind of genus. It divide a kind of denotation that means some kind of aggregations into existence and nonexistence. And it divide a kind of connotation that means some kind of attributes into same and difference. When early Chinese philosophers make distinction and demonstration the correspondence between míng[名] and shí[實], so to speak distinction mean to divide and classify into correspondence or non-correspondence, and demonstration mean to argue about the division and classification. Therefore the concept of '$l{\grave{e}}i$[類]' is a criteria that is to divide and classify the correspondence between míng[名] and shí[實] in integrated concept system of 'míng[名]'.

In this study, investigated the possibility of quantitatively and qualitatively analyzing Korean ancient glasses via Raman Spectroscopy. We subjected four categories of Korean traditional glasses, namely, lead-BaO, lead, potash, and soda glasses (3, 3, 10, and 10 pieces, respectively), to this analytical technique. The results showed significant differences between the stretching and bending Raman vibration regions corresponding to these different Korean ancient glass types. Specifically, the stretching vibration regions corresponding to lead-BaO and lead glasses showed peaks at 1040 and 1000 cm^-1, respectively; the stretching vibration region of normal glass appears at 1100 cm^-1. The bending vibration regions corresponding to potash and soda glass showed Raman peaks at 490 and 560 cm^-1, respectively. Furthermore, the Raman spectra of the lead and lead-BaO glasses showed red shifts, which depended on the amount of PbO present. Thus, our findings highlighted the possibility of quantitatively determining the amount of PbO, a major component of lead glasses, via Raman Spectroscopy.

In recent years, there has been significant interest and research on the Comprehensive Index of Character in the Warring States Period, which has resulted in many scholarly achievements. Hence, it is necessary to comprehensively categorize and summarize these achievements. Some researchers have already done a good job in this categorizing and summarizing. However, there is still work to be done in the comprehensive collation of the seal character research of the Warring States Period. The purpose of this essay is to regionalize the "SiMaZhiXi" Seal collected by "GuXiHuiBian (古璽彙編)" 0024. The number 0024 seal is an ancient seal collected by "Guxihuibian" (古璽彙編). In general, this is a Chu seal from the Warring States Period. But some scholars think that the seal is actually from the Qi or Yan States.

In this Paper a split bandwidth wideband speech coder and its highband coding method are Proposed. The coder uses a split-band approach. where the wideband input speech signal is split into two equal frequency bands from 0-4kHz and 4-8kHz. The lowband and the highband are coded respectively by the 11.8kb/s G.729 Annex E and the proposed coding method. After the LPC analysis, the highband is divided by two modes according to the properties of signals. In stationary mode. the highband signals are compressed by the mixture excitation model; CELP algorithm and W (Matching Pursuit) algorithm. The others are coded by the only CELP algorithm. We compare the performance of the new wideband speech coder with that of G.722 48kbps SB-ADPCM and G.722.2 12.85kbps in a subjective method. The simulation results show that the Performance of the proposed wideband speech coder has better than that of 48kbps G.722 and no better than that of 12.85kbps G.722.2.

The body composition of an ancient roofing tiles excavated from Chonnam province has been investigated by X-ray diffraction, and inductively coupled plasma spectroscopy. Ancient roofing tiles were excavated at ancient mountain fortress and kiln sites. The body composition of roofing tiles was different according to the excavated sites. The mineral component of roofing tiles were grouped in the five types and chemical composition was different according to the excavated areas. It is presumed that the body of roofing tiles used low-grade raw materials containing $Fe_2O_3$ 4-10%. The trace element composition of the roofing tiles were different, and it might be all ret1ection of different geological characteristics. The characteristic element of rooting tiles was vanadium element of the analyzed 20 trace elements. By $SiO_2-V$ distribution diagram types, roofing tiles excavated from the Geomdan mountain fortress at Sunchon, kiln site in Yeochon, Gorak and Cheoksan mountain fortress at Yeosu were grouped into the same excavated site.

The Altamira Cave painting which Spain which is a world-wide cave painting will know, France Grotte de Lascaux painting, observes the France Chauvet Cave and sees and about Choungryongdo with the Sangyoungchong which are an ancient tomb mural of Korea introduces. This paper provides an overview of the rock art of the Northern Mariana Islands and particularly as the rock art discovered to date predominantly pertains to ancestor worship within the Chamorro cultural group. For centuries, the Western world has categorized the ancient Chamorro inhabitants of the Marianas Archipelago as a "prehistoric" people; a people without a written history. In addition to providing an overview of the rock art of the Northern Mariana Islands, this paper also emphasizes the fact that the ancient Chamorros did indeed have a recorded history and that this chronological record exists in the pictographs and petroglyphs that they painted and carved.

In this study the foundation methods which our ancestors, through a historical age as early as three kingdom's period, adopted for their civil structures and buildings have been reviewed by investigating the discovered relics. It is shown that they already, from about 2000 years ago, had applied various foundation techniques considering the structure types and the foundation soil conditions. The ancient foundation methods are categorized as artificially laid alternating soil and boulder layers under heavy structures, compacted soil base under wide loaded area, stone column under pillars of buildings, stacked long stone footing for special buildings such as palace buildings, and piling for bridges, They are analyzed with respect to current foundation techniques.
