案例一[背景资料]某大学图书馆进行装修改造，根据施工设计和使用功能的要求，采用大量的轻质隔墙。外墙采用建筑幕墙承揽该装修改造工程的施工单位根据《建筑装饰装修工程质量验收规范》规定，对工程细部构造施工质量的控制做了大量的工作。该施工单位在轻质隔墙施工过程中提出以下技术要求：(1)板材隔墙施工过程中如遇到门洞，应从两侧向门洞处要求依次施工；(2)石膏板安装牢固时，隔墙端部的石膏板与周围的墙、柱应留有10mm的槽口，槽口处加泛嵌缝膏，使面板与邻近表面接触紧密。(3)当轻质隔墙下端用木踢脚覆盖时，饰面板应与地面留有5～10mm缝隙；(4)石膏板的接缝缝隙应保证为8～10mm。设施工单位在施工过程中特别注重现场文明施工和现场的环境保护措施，工程竣工后，被评为优质工程。[问题] 描述板材隔墙的施工工艺流程。
案例二[背景资料]某建筑工程建筑面积205000m2，混凝土现浇结构，筏板式基础，地下三层，地上十二层，基础埋深12.4m，该项工程位于繁华市区，施工场地狭小。工程所在地区地势北高南低，地下水流从北向南。施工单位的降水方案计划在基坑南边布置单排轻型井点。基坑开挖到设计标高后，施工单位和监理单位对基坑进行验槽，并对基底进行了钎探，发现地基东南角有约350m2软土区，监理工程师随即指令施工单位进行换填处理。工程主体结构施工时，二层现浇钢筋混凝土阳台在拆模时沿阳台根部发生断裂，经检查发现是由于施工人员将受力主筋位置布置错误所造成的。事故发生后，业主立即组织了质量大检查，发现一层大厅粱柱节点处有露筋；已绑扎完成的楼板钢筋位置与设计图纸不符；施工人员对钢筋绑扎规范要求不清楚。工程进入外墙面装修阶段后，施工单位按原设计完成了965m2的外墙贴面砖工作，业主认为原设计贴面砖与周边环境不协调，要求更换为大理石贴面，施工单位按业主要求进行了更换。[问题] 施工单位和监理单位两家单位共同进行工程验槽的做法是否妥当？说明理由。
On June 15, 1991, thousands of roofs collapsed due to the wet volcanic ash deposits.
Perhaps shyness would be less of a problem if we considered it a special grace to be celebrated, rather than a disease to be cured. Shyness may even be a necessary element in developing and maintaining intimacy. And, paradoxically, maybe we can only act publicly in a vital way so long as shyness guards the sanctuary of our privacy. To offer a panacea to shyness, to sing of its virtues, may allow it to assume an honored place within the economy of emotions. Before we begin, let us eliminate certain extremes from our definition of shyness. At times of disease, tragedy, and radical transitions, most of us have flashes of rampant paranoia, when the world seems hostile, other people are strangers, and we are too vulnerable to be open to chaos. Fortunately, these moments pass, for all except those who become imprisoned within neurosis or psychosis. But momentary fear is not to be confused with its distant relative-shyness-nor can it be eliminated by any means short of lobotomy. Normal shyness is, at worst, a tendency to withdraw from contact with anything that is strange, it is rooted in feelings of inferiority and low self-esteem. But, at best, shyness may be inexperience, modesty, or reserve, an inner trembling in the face of novelty. If the social situation demands that we move toward intimacy more rapidly than is comfortable, shyness is a painful reminder of the distance between social demands and our private rhythms. All of us are shy at times, because the world is full of wonders, and we are small and relatively ignorant. To value shyness is to cherish the interior life it protects. Within each of us is a private world filled with vulnerable and savage thoughts, feelings, and dreams. It is within this inner wilderness that the uniqueness of the self dwells. Beneath the social roles we have agreed to play, beneath the personality, the essential self remains free. The will and the imagination are untamed. To be a person is to know that the sum of my behaviors is only a small part of my self. In my solitude, I may entertain thoughts as intricate as Aristotle’s or as twisted as de Sade’s, or watch a conflict between duty and desire as fierce as any civil war. We are poverty-stricken when we are conditioned to assume only an extroverted social identity and to neglect the inner life. Shyness is a natural defense of our vulnerable sanctuary of self against the intrusion of insensitive and careless strangers. Nobody but a fool keeps open house for all comers. Friendship requires time and commitment. And the barriers of shyness fall of their own accord when a relationship lengthens and deepens in trust. A look at the social and psychological imperatives in a technological culture shows why shyness has come to be considered a disease that must be cured. Technology conditions us to believe that speed, efficiency, and productivity are of prime value. Hence, we come to understand ourselves on the model of the machine: our brains are elaborate biocomputers housed in a feedback apparatus called a body. To exist in this Brave New World, we have learned to divide our time into convenient segments(40-hour weeks) for efficient management and to develop enough aggression to beat the competition. To prepare ourselves to live in a competitive world, we adopt what Erich Fromm called a"marketing orientation." We construct personalities that are stylish and conform to the demands of a market economy. The author believes which of the following is necessary to survive [A] Speed, efficiency, and productivity. [B] Intimacy and gentleness. [C] Modesty and a marketing orientation. [D] Shyness and friendship.
