Objectives: The basis research of aged people's healthcare technology is very important, because our nation goes into an aged society rapidly. Especially in traditional medicine, pulse shapes of aged people were supposed to weak and empty pulse until now, but any objective measurement and compare research do not taken. Methods and Results: Therefore in this study we design observation study to find characteristic of pulse between younger group (age $20{\sim}30$) and elder group (age $43{\sim}80$) in Busan area. We used 3-dimensional pulse analyzer '3-D MAC' (Daeyomedi Co., Ltd.). And major parameters for comparison are 1) pulse height (h1), 2) applied pressure, 3) pulse power (energy), 4) high pressure duration (w) and 5) R-AI. Conclusions: According to analysis result, elder people's pulse has more large value in pulse height, applied pressure and pulse power than younger's that. It reveals that elder people in modernized lifestyle has Yang symptoms as well Yin symptoms. Consequently we need new method to care elder people's health, and this means more important direction than old text book. From now on verification research with objective diagnosis device like 3-D MAC, must be activated to build of evidence in traditional medicine. Cause traditional medicine's spirit of care and prevention is suitable to care elder people's cardiac and cerebral vascular disease those are have close relation with elder people.

Ilmenite mine was developed in the anorthosites which intruded Precambrian Jirisan gneiss complex in Wolheongri, Okjong-myeon, Hadong. Ti-ore bodies are confined to the intercumulated type anorthosites, where REE-bearing allanite occurred as veins. The chemistry of allanites shows relatively low in CaO (11.02~12.81 wt%), but high in ${\Sigma}R_2O_3$ (R = Ce, La, Nd) (17.21~21.58 wt%), respectively. Abnormally high radioactive detection ascribes to the presence of small particles of thorium mineral known as thorite ($ThSiO_4$). Thorite shows 65~72.78 wt% ($ThO_2$) and 5.49~12.78 wt% ($UO_2$) in composition. The radioactive prospecting could be a strong tool to find REE-bearing allanite which is closely associated with Ti-ore deposits.

The geology of the Tumbang Lapan area consists of Permian to Carboniferous metamorphic rocks, Cretaceous granitic rocks, and Permian to Tertiary sedimentary and volcanic rocks. Three faults are developed in surveyed area, and are functioned as channels of the hydrothermal solution which farmed quartz veins within tuff3. In the mineralized area, argillic and propylitic alterations are dominant. Argillic altered rocks show the alteration mineral assemblages of kaolinte+sericite+quartz+chlorite+pyrite. Mineral association in propylitic alteration is chlorite+epidote+feldspar+quartz+pyrite+ magnetite. Vein type, fracture filling, stockwork are observed in survey area. As a result of analysis of samples from quartz veins and altered rocks, some mineralized rocks showed $0.01\~4.6g/t$ of gold.

Until 2014, 14 million tonnes of Pb (metal based) and 41 million tonnes of Zn (metal based) were produced in Peru. Representative two Pb-Zn metallogenic belts were known in Peru. They are lower Cretaceous-Paleocene VMS Cu-Zn-Au metallogenic belt and Miocene epithermal, skarn, replacement & polymetallic vein metallogenic belt. If four new mining projects were launched and additional three mining projects were prepared until 2017, it seems possible to produce 0.34 million tonnes of Pb and 1.5 million tonnes of Zn additionally. In Pb-Zn metallogenic belt in Peru, potential Zn amounts range from 9 to 6000 million tonnes with 0.1 to 14% Zn and potential Pb amounts range from 5 to 2800 million tonnes with 0.04 to 5.3% Pb.

The pulse diagnosis is an important method in Oriental Medicine. Recently, there have been continuous attempts to replace the finger palpation by Oriental medical doctors (OMDs) by more objective tools based on machines, e.g., pulse analyzers. To improve the performance of the pulse analyzers, both the machine-appropriate interpretations for the pulse images appeared in the literature and the improvement in the repeatability and reproducibility of the measurement sensors are to be developed. As an attempt towards the transformation of the pulse images in terms of machine-appropriate language, in this work, we suggest an upgraded algorithm for the solid/deficient pulses, which are the two representative pulse images informing us how strong the pulse pressure is. It has been argued that one could determine the solid/deficient pulses by the maximum pulse pressure from pulse analyzers. However, by a clinical test, we found that the maximum pulse pressure alone is not sufficient to determine the solid/deficient pulses. In addition to the maximum pulse pressure, the mean pulse pressure averaged over for five different hold-down pressures(3-D MAC) is needed to improve the agreement with the OMD's decision for the solid/deficient pulse. We found that, among the data diagnosed with having either the solid pulse or deficient pulse by OMDs, the novel algorithm showed 86.0% diagnosis rate and 81.6% concordance rate.

In this work, we report the diagnostic relations among some primary pulse conditions such as the floating/sunken, deficient/forceful, large/fine, and the long/short pulses. For this purpose, we carried out a clinical test, in which 11 Oriental medical doctors had participated to diagnose the pulses for 1566 healthy subjects. The subjects were divided into 11 subgroups and each subgroup was allocated to an individual doctor. It resulted in that, for 847 subjects (54%), two or more than two pulse conditions were felt simultaneously, for which we counted the frequency of the pairs of the pulse conditions. For the statistical analysis, we used a Chi-square test. As a result, at high frequency, the forceful, large, and the long pulses were diagnosed in pairs or in their triplet, and a similar close relation was found between the deficient, fine, and the short pulses. The pairwise diagnoses of the pulse conditions between the forceful, large, and the long pulses, and between the deficient, fine, and the short pulses imply their close relatedness in clinics. This result is supported by the theory of deficiency/excess syndromes. Moreover, we show that the close relatedness among the pulse conditions can be understood in terms of the geometric features of the radial artery near the prominent bone. This is the first work which reports the relatedness between the primary pulses by an objective clinical test.

Ilmenite deposits are developed along the Precambrian intercumulated anorthosite body in Jikjeon-Ri, Bukcheon-Myeon, Hadong, Korea. Both detailed geological survey and drilling prospecting data for seven boreholes can be used to do resource estimation with GOCAD S/W. 3D modeling using geostatistics is applied to predict the shape and size of Ti ore bodies. As a result, 5 Ti ore veins occurred along N-S direction and average grade of Ti and ilmenite resources are calculated as 2.98 wt% Ti and 7,494,303 metric tons ilmenite ore reserves (Ti 223,330 t). This 3D modeling will be applied to the whole ilmenite deposits in Hadong-Sancheong area to predict the exact distribution and resources estimations of Ti ores.

The geology of the Apdong Nb-Ta deposit, is hosted by alkali metasomatites, consist of Upper Proterozoic sedimentary rocks, alkali syenites(Hoamsan intrusive) of Phyonggang Complex(late Paleozoic to early Mesozoic), Jurassic granite and Quaternary basalt. Alkali syenites are distinguished as alkali amphibole-pyroxene syenite, alkali amphibole-biotite syenite, biotite-nepheline syenite, biotite syenite, and quartz-alkali amphibole-pyroxene syenite. Alkali metasomatites are the products of intense post-magnatic metasomatism, and form the Nb-Ta ore bodies as the belt, irregular vein and lenticular types in the southern part of Hoamsan intrusive. The ore mineralization is characterized by the occurrence of pyrochlore, zircon, and small amounts of columbite, fergusonite. magnetite, fluorite, molybdenite, ilmenite, titanite, apatite, and monazite. Pyrochlore is one of the niobium/tantalum oxides and contains substantial amounts of rare earths and radioactive elements. The compositional varieties of pyrochlore can be defined: (1) enriched in tantalum, uranium and cerium, (2) substantially tantalum- and fluorine-poor, and (3) enriched in thorium or barium. The geochemical characteristics, ore textures and mineral occurrences indicate that alkali metasomatism of the mineralizing fluid was the dominant ore-forming process.

The examination of pulse, which is a typical palpation technique in the oriental medicine, has been used conventional analog system for discrimination of 28 pulses. However, the clipping phenomenon in the pulses, which used same feature extraction technique with ECG signals, has been occurred in analog system due to feature extraction method and over amplification from the input signals. It caused inaccurate to analyze the pulse signals. In this paper, we propose a digital filter design technique based on Prony's method for signal modeling and C-spline interpolation for feature extraction from pulse signal to compensate analog pulse detection system. In addition, we suggest a compensated electronic pulse detection system comprising new pulse analyzing algorithm and shape analysis technique for pulses, which were difficult to use in analog system. The feasibility for new proposed system has been confirmed comparing output signals between electronic pulse detection system having proposed filter design techniques with pulse analyzing algorithm and conventional analog system.
