Particle size distribution of pine pollens was investigated by laser diffraction method. Size distribution pattern, surface area per volume, mean particle size were different among five pollens with different local origins. When pollen was wet particle size increased from 24% to 75% for maximum size(99% distribution) and 12-18% for mean size(50% distribution) depending on locality. These results were well consistent with light microscopic data and bulk density. Pollen size showed normal distribution with dual peak either separated or overlapped in the large size. Mean size of dry pine pollen ranged from 40 to 51㎛, minimun(10%) from 31.3 to 39.8㎛ and maximum(99%) from 59.3 to 115.9㎛. Volume surface ranged from 0.12㎡ to 0.222㎡/㎤. Bulk density was 0.25g/㎤. Particle size distribution by laser diffraction method will be useful to assess pine quality, local origin and plant origin
The Properties of L-lower Approximation Operators
김용찬 한국지능시스템학회 2014 INTERNATIONAL JOURNAL of FUZZY LOGIC and INTELLIGE Vol.14 No.1
In this paper, we investigate the properties of L-lower approximation operators as a generalizationof fuzzy rough set in complete residuated lattices. We study relations lower (upper,join meet, meet join) approximation operators and Alexandrov L-topologies. Moreover, wegive their examples as approximation operators induced by various L-fuzzy relations.
(L,e)-filters on complete residuated lattices
김용찬,고정미 한국지능시스템학회 2012 INTERNATIONAL JOURNAL of FUZZY LOGIC and INTELLIGE Vol.12 No.3
We introduce the notion of (L; e)-filters with fuzzy partially order e on complete residuated lattice L. We investigate (L; e)-filters induced by the family of (L; e)-filters and functions. In fact, we study the initial and final structures for the family of (L; e)-filters and functions. From this result, we define the product and co-product for the family of (L; e)-filters and functions.

연구 계획: 종설. 목적: 골반과 요추부 퇴행성질환 환자들의 상호 관계에 대한 최신 지견을 제시하고, 요추부 퇴행성질환 환자들의 시상면 정렬에 대한 골반의 역할을 강조하고자 한다. 선행 문헌의 요약: 골반과 요추부 퇴행성질환 환자들의 시상면 정렬간의 관계에 대해서는 논쟁의 여지가 있지만, 많은 저자들은 골반이 요추부 퇴행성 질환 환자들의 시상면 정렬에 대해서 의미 있는 영향을 미친다고 보고해 왔다. 대상 및 방법: 저자들은 골반과 요추부 퇴행성질환 환자들에 대한 참고 문헌들을 검색하였고, 지난 30년간의 문헌에 대해 꾸준히 추적 관찰하였다. 결과: 골반과 요추간의 관계는 전 인체 시상면 정렬에 영향을 미친다. 또한 골반과 요추부 퇴행성질환 환자들의 시상면 정렬간에는 매우 밀접한 상호관계가 있다. 따라서 골반과 요추는 요추골반복합체(Lumbopelvic complex)라는 하나의 개념으로 간주되어야 한다. 결론: 우리는 요천추관절(Lumbosacral joint)이 아닌 요추골반관절(Lumbopelvic joint)의 개념을, 그리고 요추전만(Lumbar lordosis)이 아닌 요추골반전만(Lumbopelvic lordosis)의 개념을 가질 필요가 있다. 또한 전 인체 시상면 정렬과 동적 균형을 평가하기 위하여 요추골반복합체를 고려해야만 한다. Study Design: Literature review. Objectives: To present updated information on the relationship of the pelvis and lumbar degenerative disease (LDD) patients and to emphasize the importance of the pelvis in sagittal alignment of LDD patients. Summary of Literature Review: Although the relationship of the pelvis and sagittal alignment of LDD patients is controversial, many authors have reported a significant impact of the pelvis on LDD sagittal alignment. Materials and Methods: The authors identified references through a literature search on the pelvis and LDD and continuous monitoring of the literature during the past 30 years. Results: The pelvis and lumbar levels were related to whole-body sagittal alignment. The pelvis is also closely related to sagittal alignment of LDD patients. Therefore, the entire area should be regarded as a lumbopelvic complex. Conclusions: We need to consider the concept of a lumbopelvic joint and lumbopelvic lordosis, not a lumbosacral joint and lumbar lordosis. We must also evaluate the lumbopelvic complex to assess whole-body sagittal alignment and dynamic balance.
