摘要In this note, we show that a proposed secure broadcasting scheme is insecure. We also present a modified scheme to overcome this weakness. The modified scheme has the extra advantage that each participant can derive his group keys from group identities without the need of knowing other information.

摘要社會進步加上醫療環境的巨變,對於醫院的經營管理產生極大的衝擊,因此醫管專業也越來越受重視,而我國醫管人才的培育管道從專科到研究所都有,尤其在近幾年面臨教育制度的改革,許多原本以培育醫管人力的專科學校,紛紛升格為技術學院,從人力素質層面而言,可使專科畢業生多了一個選擇進修的機會,對整體素質的提升有其正面的意義,但從人力應用層面而言,專科學生畢業後多數選擇繼續升學的傾向,也影響到學校的課程內容與設計,甚至扭曲了醫管專科以培養醫院中基層實務專業人員的教育目標。此外,就技專校院設立的宗旨,在於培養專業技術及管理人才以符合產業及工作所需的目的來看,設有醫管科系所的學校其所開設的醫管相關專業課程,是否能滿足醫療相關工作的需要,便是本研究主要探討的目的。本研究主要針對衛生署在84至86年評鑑合格的區域級以上醫院及各級衛生機關(包括衛生署、衛生局、中央健康保險局總局及各分局)首長,進行郵寄問卷調查,研究結果顯示有高達93.5%的醫院內有進用醫管人力,而衛生機關則僅有50%有進用醫管人力,對於未來醫管人力的培育方式而言,多數醫院院長建議以大學(含二技及四技)以上最適當,而衛生機關首長則建議以研究所方式為宜。此外,醫院院長也建議醫管人力應加強醫療行銷管理、醫療品質管理、醫療財務管理、醫療資訊管理及保險申報實務等學科的訓練,而衛生機關首長則建議應加強其衛生行政與醫療政策、流行病學、醫療保險制度、醫療相關法規及醫療品質管理等學科的訓練。

類別期刊論文
摘要We assume $(R,+,\cdot)$ is a ring with unit. Let $\cu (R)$ denote the set of invertible elements and suppose $\Phi$ is a subgroup of $\cu (R)$ with $-1\in\Phi$. Define an equivalence relation $\sim$ on $R^* R \setminus \{0\}$ by $s_1 \sim s_2$ if there is $b \in \Phi$ such that $bs_1 s_2$. Let $s_1, s_2, \dots ,s_{m}$ be representatives of the distinct equivalence classes. Define $A_i\{\{x,y\}\mid (y-x)\sim s_i\}$ for $i1,2,\dots,m$. We prove that $(R, \ca)$ is an association scheme, where $\ca \{A_i\mid i 1, 2,\dots, m\}$. Next suppose $R$ is finite and let $S$ be a proper subset of $R$ with $|S|\geq 2$. Define $\cb \{bS+a\mid b\in\Phi,\,a\in R\}$. Then $(R,\cb,\ca)$ is a PBIBD\,(partially balanced incomplete block design). Moreover, if $S$ satisfies $S\ne -S+a$ for any $a$, then the above PBIBD can be partitioned into two isomorphic PBIBDs. The application of PBIBDs to constant weight codes is introduced.

類別期刊論文
摘要Planar nearrings, like most of the subjects in finite geometries, can be applied for the construction of block designs. In this article we introduce the ideas of constructing simple BIBDs (balanced incomplete block designs) from field-generated (or nearfield-generated) planar nearrings. Further investigation reveals that there are strong connections between these kinds of constructions and the action of a sharply $2$-transitive group on a set. We next explore the structures of the constructions. The theory is derived from finite fields directly. The main point is on finding a subset $S$ (called generating block) of the field $F$ with respect to the given stabilizer $Stab_{F^*}(S)$. A big portion of simple BIBDs with various parameters can be obtained in this way; many simple BIBDs with the same parameters appear. We classify the constructed BIBDs according to the types of the respective generating blocks.

名稱More Results on the Existence of Simple BIBDs with Number of Elements a Prime Power

類別期刊論文
摘要We study the existence of simple (q,k,λ) BIBDs when the number of elements is a prime power q and {c1,c2 }∩{1,2} is not empty, where c1gcd(k,q−1) and c2gcd(k−1,q−1). We show that in many situations the necessary conditions λ(q−1)≡0 mod (k−1), λq(q−1)≡0 mod k(k−1), and λ≤C(q−2,k−2) are also sufficient for the existence of a simple (q,k,λ) BIBD. These new results improve the valid range of simple BIBDs.
